Xue, Chaoyang. „Les sources de HONO atmosphérique rural et leur impact sur la qualité de l'air régional dans la Plaine de Chine du Nord“. Electronic Thesis or Diss., Orléans, 2020. http://www.theses.fr/2020ORLE3107.
Der volle Inhalt der QuelleAir pollution is still an environmental problem that urgently needs to be solved in the North China Plain (NCP). With the aim to explore nitrous acid (HONO) formation and its impact on regional air quality in the NCP, the development and systematic assessment of instruments to measure atmospheric HONO concentration and soil HONO emission flux were realized. Based on field measurements, a 3D chemistry-transport model (the Community Multiscale Air Quality Modeling System, CMAQ) and a box (0D) model (Master Chemical Mechanism, MCM) were used to explore the HONO budget and its impact on regional air pollution, e.g., summer ozone (O3) pollution and winter haze pollution. We found that agricultural soil was an important HONO source with a significant impact on regional O3 pollution in the summertime. A new soil HONO emission mechanism related to nitrification was proposed. HONO also plays an important role in atmospheric oxidizing capacity and deteriorating regional air quality in the wintertime

Der volle Inhalt der QuelleThis Ph. D. Traces the creation and the development of modern water supply in the city of Tianjin and analyses the impact of demography and economic growth on the water resources. The creation of a modem water supply in Tianjin follows the arrival and the settlement of Foreigners in Tianjin at the end the 19th Century. The first Waterworks is created in 1897 in the British Concession. A second Waterworks is founded in 1903 that supplies the Chinese city and the other Foreign Concessions. Both companies' activity growths during the 1900s and up untill the 1930s, at a lower rate, however, during the 20s and 30s because of the warfare that raged Tannin region during that period. The Japanese occupation and the GMD's control of the tow and the civil from 19461eave the city modem water supply in a state of neglect and ineffectiveness
Allès, Élisabeth. „Des chinois musulmans dans la plaine centrale : une approche anthropologique des hui du henan“. Paris, EHESS, 1998. http://www.theses.fr/1998EHESA030.
Der volle Inhalt der QuelleWhat means today being a hui ? what are the relations between han and hui. How do the hui conceive themselves and the others? what are the social practices of this double identity, both muslim and chinese ? what is here the role of religion, and what are we think of that islam which accepts within itself women's mosques ? many interpretations of this hui identity have been proposed. Are the hui a group confronted with the dilemna between assimilation and antagonism ? or are we to talk about syncretism ? any description which would immobilize individuals and groups into a fixed identity would prevent us from understanding realities which are much more instable. We have concentrated our investigations on the henan where the hui, though a minority, are nearly one million. Fieldwork made over a long period and at various points of time provides the materials for our reflexion. In our inquiries, whether about doctrine or about ritual, we never met anything corresponding to the classical definition of syncretism. There is never mixing, but always juxtaposition, and in the people's mind, the latter doesn't seem to make any difficulty : where observers from abroad would expect to find tensions, coexistence of dissimilar elements seems altogether natural. As happens in other contexts or regions, for instance in nepal or india, the double cultural reference is used in different ways according to situations. As to the place the hui hold within chinese society, here is a community which has always been a minority group and has during its whole history put up with that status. Moreover, they always considered themselves as an integral part of chinese society and knew how to bind their cause to that of those movements which agitated it in its depth

Der volle Inhalt der QuelleThe Tibetan Plateau is a classical example of a continental collision, but the geodynamical processes that led to its formation and that govern its present day evolution remain unclear. Several conflicting concepts, involving various deformation mechanisms, have been proposed. In 1998, a network of seismic stations, essentially designed to record long distance earthquakes, was deployed across the Northeastern margin of the plateau. This region is assumed to be the part where present-day growth of the plateau takes place; it is thus the right place to understand the mechanisms that led to the formation of the plateau as a whole. We applied two complementary seismic methods, teleseismic tomography and receiver functions analysis, to the data recorded during this experiment. This joined approach helps us to better image the crust and the mantle of this area. The lithosphere, and especially the crustal part, exhibits important lateral variations in both structure and composition, whereas the asthenospheric mantle is relatively homogeneous. The crust thickens towards the centre of the plateau by successive "steps" of the crust-mantle interface, located near reactivated Mesozoic sutures. The seismic velocity ratio VP/VS indicates variations in the crustal composition depending on the considered geological unit. But these values are not in favour of widespread partial melted zones in the crust. Finally, several observations indicate that the Kunlun fault extends through the whole crust and concentrates most of the deformation. This large strike-slip fault seems also to be associated with ongoing subduction of the North Kunlun block toward the south. This inducing probably partial melt in the mantle and intrusion of magma into the crust. Our results can be seen as an indication of buried plate tectonics inside the Tibetan Plateau

Der volle Inhalt der QuelleSettlement spatial organization in China has yet to be intensively investigated for the critical transition between the end of the Neolithic to the beginning of the Bronze Age, two periods which usually constitute separate fields in Chinese academia. In order to conduct a thorough study of this transition, this dissertation synthesizes the vast and growing corpus of excavation and mapping data of archaeological sites in order to highlight variations of spatial occupation and changes of population dynamics. This includes a comprehensive definition of the chronological and geographical parameters of these periods that integrates previous research with a systematic GIS database. A statistical and spatial analysis of settlement distribution within the entire Central Plains shows the exchanges network that structured the human occupation. A subsequent regional-scale analysis allows us to analyze spatial occupation density and demographic evolution. These analyses help to build new paradigms for understanding multi-rhythm temporality in early China and redefine the main characteristics of the significant transition period between the end of the Neolithic and the Early Bronze Age

Der volle Inhalt der QuelleEight mechanical boreholes carried out in the extreme western (French) part of the Flemish coastal plain were variously analysed together with descriptions from 1000 cores obtained between 1974 and 2005 with the aim of contributing to a better understanding of the Holocene deposits, processes and sea-level history. The analysis of the mechanical boreholes has essentially involved determination of bedding, grain-size changes and foraminiferal assemblages. Additional analyses of quartz grain surface features under the scanning electron microscope and of the geochemistry of these deposits were also carried out. A total of 56 radiocarbon ages were obtained from various sites and depths throughout the study area. The global stratigraphy of the deposits consists of four units overlying the Pleistocene substratum. Unit 1 above the Pleistocene substratum corresponds to a widespread basal freshwater peat. Unit 2 comprises interbeds of peat and organic horizons with clayey tidal flat sediments and is capped by a relatively thick intermediate (to surface) peat that represents the widespread development of freshwater marshes. Unit 3 corresponds to a new phase of tidal flat sedimentation consisting of silt and/or clay overlying the surface peat. This unit represents the end phase of tidal plain infill which also comprises sandy or finer-grained tidal channel fill deposits. Unit 4 corresponds to dune, beach, and shoreface deposits marking the development of barrier formations that finally closed off the tidal plain from the sea. Phases of development of this unit, a full subject in its own right, are not considered in this thesis. The radiocarbon ages obtained from the peat beds in this part of the coastal plain have enabled the construction of a sea-level curve covering much of the Holocene from about 8000 cal BP. The sea-level history established from these ages and from more detailed studies in the Belgian part of the plain clearly show that the older interpretation of these deposits in terms of late Holocene transgressions and regressions is not valid and should be completely discarded. The sedimentary environments show strong spatio-temporal variability hinged on several parameters. These include the rate of sea-level rise relative to sediment supply (accommodation space), the morphology of the Pleistocene substratum, the proximity of fluvial and tidal channels, and of the sea. Among these parameters, the only one of regional extent is sea-level rise. Sedimentation has undoubtelly involved constant adjustements between accommodation space created by sea-level rise, sediment supply which infilled this space and the behaviour of tides, notably variations in tidal range and asymmetry and their influence on tidal channel morphology and hydrodynamics, and sediment compaction. The behaviour of intercalated beds, notably peat beds, had a strongly local character, thus imprinting marked spatio-temporal stratigraphic diversity. At the base, infill of irregularities in the Pleistocene surface is discontinuous over time. The proximity of the sea (base level) created conditions of impeded terrestrial drainage favourable to the widespread development of freshwater marshes and subsequent peat. The sandy/silty sedimentation that followed occurred under tidally dominated conditions associated with sea-level rise. The marked slow down in sea-level towards 5500 cal BP, especially well documented by the Belgian studies, enabled anew phase of (surface) peat development. At this stage, as a result of the very slow rate of sea-level, control of tidal flat sedimentation was relinquished to other parameters, notably morphodynamic, dominated essentially by changes in tides and tidal channel activity and by compaction of deposits, especially peat

Der volle Inhalt der QuelleWang, Bo. „Evolution géodynamique du Bloc de Yili(nord-ouest Chine) au Paléozoïque“. Phd thesis, Université d'Orléans, 2006. http://tel.archives-ouvertes.fr/tel-00140948.
Der volle Inhalt der QuelleChinois occidental. Il est considéré comme un micro-continent avec un substratum précambrien
qui se prolonge vers l'Ouest au Kazakhstan, mais ses limites ne sont pas claires. Le Bloc de Yili
est important pour comprendre l'évolution géodynamique du Tianshan Paléozoïque qui résulte de
processus de subduction et collision polyphasés. Classiquement, la chaîne du Tianshan est divisée
en trois domaines: le Tianshan Nord, le Tianshan Central et le Tianshan Sud. Mais nos travaux
structuraux, géochimiques et paléomagnétiques suggèrent que ces domaines et leurs limites
doivent être redéfinis.
Le bloc de Yili était auparavant considéré comme l'extension vers l'Ouest du Tianshan
Central. En fait, il s'agit d'un arc magmatique Dévonien-Carbonifère situé sur un socle continental
protérozoïque et une plate-forme sédimentaire du Paléozoïque inférieur. Des roches volcaniques
d'âge Carbonifère sont très répandues sur les bordures du bloc de Yili. Leurs caractéristiques
pétrologiques et géochimiques montrent 1) qu'il s'agit surtout d'andésites, de rhyolites et plus
rarement de basaltes appartenant à la série calco-alcaline, 2) que les importantes anomalies en Nb
et Ta s'accordent avec des magmas liés à une subduction, 3) que les dicriminations fondées sur les
HFSE placent ces roches dans le champ des arcs continentaux. Les études isotopiques Rb-Sr et
Sm-Nd indiquent que ces roches magmatiques sont issues d'un réservoir magmatique situé dans le
manteau appauvri. En considérant les formations sédimentaires de faible profondeur associées au
magmatisme, on suggère que les roches magmatiques carbonifères se sont formées sur une marge
continentale active. Des datations, par ICP-MS ablation laser, de zircons issus de roches
volcaniques et granitiques de l'ensemble du bloc de Yili, indiquent des âges compris entre 389 et
310 Ma, c'est à dire fini Dévonien moyen à Carbonifère supérieur.
La limite Nord du Bloc de Yili est représentée par les turbidites du Carbonifère supérieur et le
mélange ophiolitique de Bayingou-Motuogou qui constituent le Tianshan Nord. Les données
pétrologiques et géochimiques suggèrent que les turbidites et le mélange ophiolitique représentent
un complexe de subduction. Le mélange ophiolitique résulterait d'une tectonique intraocéanique
suivie de resédimentation et de déformation pendant la subduction du bassin océanique du
Nord-Tianshan qui existait au moins depuis le Dévonien supérieur-Carbonifère inférieur d'après
les faunes de radiolaires des cherts ophiolitiques. Les données structurales, pétrologiques,
géochimiques et géochronologiques sur le mélange ophiolitique et les turbidites sont en faveur
d'une subduction du bassin océanique de Nord-Tianshan vers le Sud, est responsable de la
formation de l'arc magmatique de Yili. Comme ce complexe de subduction a été redéformé et
charrié vers le Nord sur le bassin Cénozoïque du Junggar, la véritable suture du Nord Tianshan est
cachée par les chevauchements cénozoïques. La prolongation orientale du Nord Tianshan se
trouve dans l'arc de Bogda qui est composé de sédiments carbonifères, de volcanites et de
granitoides. De nouvelles données géochimiques dans la région de Houxia indiquent que les
dolérites, andésites et dacites rhyolitiques sont des volcanites d'arc d'affinité calco-alcaline. La
cohérence temporelle et la corrélation spatiale entre le complexe de subduction du Tianshan Nord et l'arc de Bogda suggèrent que la suture du Tianshan Nord se prolonge vers l'est, où elle serait
cachée sous l'arc de Bogda par le chevauchement tertiaire.
La limite sud du bloc de Yili est une zone complexe polydéformée qui contient des roches
métamorphiques de haute-pression (HP), des mélanges ophiolitiques, un socle fait de roches
métamorphiques crustales et de roches sédimentaires de plate-forme, le tout affecté par des
décrochements. L'étude géologique détaillée le long de la rivière Kekesu révèle l'existence d'une
déformation ductile à faible pendage et dirigée vers le nord qui affecte des roches océaniques
métamorphisées dans des faciès de HP (schistes bleus et éclogite) et des roches continentales
interprétées comme la bordure méridionale du bloc de Yili. Des preuves d'une déformation ductile
extensive dans le faciès schiste vert sont également rencontrées le long de la Rivière Kekesu. Des
datations Ar/Ar par sonde laser de micas blancs dans des métapélites issues de schistes bleus
rétromorphosés et de quartzites dans le faciès schiste verts donnent des âges compris entre 330 et
315 Ma qui sont interprétés comme l'âge de la fin de l'exhumation des roches de HP. La formation
des roches de HP a été interprétée comme associée à une subduction vers le nord de l'océan du
Tianshan, également responsable du magmatisme d'arc de la partie sud de Yili. Cependant,
comme le magmatisme d'arc du bloc de Yili est significativement plus jeune que le pic du
métamorphisme prograde (antérieur à 350 Ma) et même que la rétromorphose, et que l'analyse
cinématique indique un mouvement vers le Nord, cette interprétation n'est pas étayée par nos
données. Par ailleurs, la structure de la rivière Kekesu est en accord avec les données cinématiques
vers le nord observées dans la région de Mishigou et Gangou, plus à l'Est. Cette dernière
correspond à la suture entre le Tianshan Nord et Central. Dans le Tianshan Central, au sud du
complexe métamorphique de HP, il n'existe pas d'arc magmatique Carbonifère, mais un arc
Ordovicien -Silurien et des turbidites du même âge. Des calcaires et des grès du Carbonifère
inférieur recouvrent en discordance l'arc d'âge Paléozoïque inférieur. Des roches métamorphiques
protérozoïques représentent le substratum de cet arc.
Dans les régions de Aheqi, Wushi, Heiyingshan, sur le versant sud du Tianshan, on rencontre
un mélange ophiolitique contenant des blocs de gabbros datés à 390 Ma avec une signature
géochimique de bassin d'arrière arc. Par ailleurs, l'évolution de la plate-forme carbonatée du
Tianshan Central vers des roches siliceuses (cherts rubanés et pélites siliceuses) suggère un
approfondissement de cette marge continentale pendant le Dévonien. Ces données s'accordent
avec l'existence d'un bassin marginal entre le Tianshan Central et le Tarim. Les observations de
terrain suggèrent que le mélange est charrié du Sud vers le Nord sur les séries carbonatées
dévoniennes du Tianshan Central. Cette déformation ductile s'est produite avant le dépôt des
séries terrigènes et carbonatées du Carbonifère inférieur-moyen qui recouvrent en discordance le
mélange ophiolitique et son substratum tectonique. Il faut cependant remarquer que les séries
carbonifères sont déformées par des plis, parfois synschisteux, à vergence Sud. Mais l'âge de cette
déformation n'est pas établi avec certitude. Il est peut-être Cénozoïque, mais des âges compris
entre le Permien et le Paléocène ne peuvent pas être définitivement écartés. Ces observations sont
en bon accord avec celles de la région de Kulehu et de Kumux-Yushugou. Ce mélange
ophiolitique correspond au Tianshan sud, il a été souvent interprété comme des klippes déplacées
du Nord vers le Sud. Dans notre interprétation, il est au contraire issu d'une suture méridionale qui
sépare le Tianshan du Tarim.
Les deux limites nord et sud du bloc de Yili ont été redéformées par les décrochements
permiens. Les turbidites du Tianshan Nord sont affectées par une foliation verticale et une linéation horizontale associée à une cinématique dextre. Nos datations Ar/Ar sur roche totale
indiquent un âge de 270 Ma qui correspond au mouvement de la faille du Tianshan Nord. Ceci
s'accorde avec les données disponibles sur la Faille Principale du Tianshan (MTSF) où les
datations se distribuent entre 280 et 250Ma. Les failles de Nalati et de Qinbulak recoupent la
limite entre les blocs de Yili et du Tianshan Central. Nos observations en plusieurs points entre
Kekesu, Laerdun, Sanghuyanzi confirment la cinématique dextre. Ces mouvements coulissants
sont associés à un magmatisme intraplaque, représenté par des granites alcalins, des basaltes
tholéiitiques continentaux, et des roches volcaniques acides. Les décrochements permiens
apparaissent comme complètement indépendants de la tectonique de convergence N-S du
Paléozoïque pré-permien. Ces coulissements jouent un grand rôle dans l'architecture finale du
Tianshan.
Afin de mieux contraindre les mouvements coulissants d'âge Permien, des données
paléomagnétiques ont été acquises sur des roches d'âge Ordovicien, Carbonifère et Permien dans
le bloc de Yili et les régions voisines. Plus de 500 échantillons de roches volcaniques et
sédimentaires ont été prélevés sur 61 sites. Les études magnétiques (minéralogie, démagnétisation,
etc...) montrent que les porteurs de l'aimantation sont la magnétite et l'hématite. Après une étude
soignée des caractéristiques de l'aimantation rémanente dans la région de Zhaosu, Xinyuan et
Gongliu, deux pôles pour le Carbonifère supérieur (C2) et Permien supérieur (P2) sont calculés
pour le bloc de Yili. La comparaison de ces pôles C2 et P2 avec ceux du même âge disponibles
pour le Tarim, le Junggar et la Sibérie indique 1) qu'il n'y a pas de mouvement différentiel
significatif entre le Bloc de Yili et le Junggar depuis le Carbonifère terminal ; 2) qu'il n'y a pas de
mouvement latitudinal significatif entre ces blocs depuis le Carbonifère supérieur ; 3) qu'il existe
des rotations anti-horaires d'environ 46± 15° et 32±15° entre l'ensemble Yili-Junggar par rapport
au Tarim et à la Sibérie entre C2 et P2. Ces rotations sont accommodées par les décrochements
dextres le long des failles bordières nord et sud du bloc de Yili et par le décrochement senestre de
l'Irtish dans l'Altaï. Il en résulte un mouvement relatif d'environ 1000 et 600 km sur ces deux
failles.
Finalement, en tenant compte des déformations Cénozoïques liées à la collision Inde-Asie, un
modèle simple de l'évolution du bloc de Yili et de l'ouest du Tianshan chinois est proposé.
Pendant l'Ordovicien et le Silurien inférieur, un bassin océanique appelé l'Océan Tianshan existait
entre le Tianshan Central et le Bloc de Yili. Cet océan a commencé à se fermer par subduction vers
le Sud pendant l'Ordovicien supérieur et le Silurien inférieur en produisant l'arc du Tianshan
Central. Entre le Silurien moyen et le Dévonien moyen, l'Océan Tianshan continue de se fermer.
La subduction océanique est suivie par la subduction continentale du Bloc de Yili sous le Tianshan
Central qui est responsable de la formation des roches métamorphiques de HP. Simultanément à la
fermeture de l'Océan Tianshan, une mer marginale s'ouvre au sud du Tianshan Central pendant le
Dévonien inférieur à moyen. Pendant le Paléozoïque inférieur, les dépôts de grès et de calcaires
suggèrent que la marge nord du bloc de Yili était une marge passive. Entre le Dévonien moyen et
le Carbonifère inférieur, à cause de la fermeture de l'Océan Tianshan, les blocs de Yili et du
Tianshan Central sont soudés pour former une seule masse continentale. A ce moment là, les
roches de HP sont exhumées. La fermeture du bassin d'arrière arc est associée au charriage du
mélange ophiolitique du Tianshan Sud. Simultanément, la subduction vers le sud d'un bassin
océanique, appelé océan Nord Tianshan est responsable de la formation de l'arc magmatique de
Yili et du complexe de subduction du Tianshan Nord. La subduction de l'Océan Nord Tianshan s'achève au Carbonifère supérieur quand se produit la collision entre le Bloc de Yili et le Junggar.
A la fin du Carbonifère, la convergence sub-méridienne (par rapport aux coordonnées actuelles)
est achevée. Tous les blocs continentaux sont alors soudés. Au Permien, les décrochements dextres
d'ampleur plurikilométrique perturbent la géométrie initiale. Par exemple, la continuité de l'arc du
Tianshan Nord-Bogda est détruite.

Der volle Inhalt der QuelleThis thesis focuses on the development of industrial cities in the northeast China: economic recession, urban renewal, etc. It aims to focus on the links between the economy and the development of cities, the obstacles during development in order to find the universality of industrial cities in this region. The thesis consists of four parts: 1. Review the history of China's industrialization and urbanization, and then summarize the resources, the evolution of industrialization and urbanization of northeast China. Through the description and analysis of Northeast phenomenon, we sum up the historical reasons and background reasons which result in its irrational industrial structure; 2. By analyzing the decline of the old industrial cities of the Northeast region, we aim to illustrate its plight and urgent problems; 3. By combining with the general theoretical basis of industrial land adjustment, the policy of the revival of northeast China put forward and implemented by the Chinese government and the current situation of industrial cities of northeast China, the thesis analyzes and proposes the development strategy of industrial land which is suitable for old industrial areas, old industrial cities and new industrial agglomerations; 4. Through the analysis of other developed industrial city, methods of updates and rehabilitation of industrial zones, the outcome after the reform measures, we try to sum up some common law by analyzing the various regions; Comparative research methods have also been taken, such as the comparison of data analysis and so on. By summing up Shanghai’experiences on the modification of industrial land and other regions’experiences, the thesis aims to put forward the appropriate proposals for the northeast industrial cities

Der volle Inhalt der QuelleLike many mediterranean regions, the plain of al-hoceima, which is overpopulated, is inhabited by sedentary country people, who hang on to their small fields. The farming of cereals and the limited rearing of animals do not satisfy the subsistance of the inhabitants. Natural factors impose a poor economy, which is based on traditional agriculture resulting in low and irregular crops. To maintain an average level of living for the inhabitants so as to limit rural exodus on the one hand and to carry out some substructure changes on the other, the government tried to help the country men by building the dam of "abdelkrim khettabi" and by developing the plain of al-hoceima, which presents the principal changes taking in this area. An examination of the new rural situation shows that government contributions consist essentially of technical things, while agrarian problems are almost ignored ; hence, the predominence of fallow lands in the plain has led to the failure of the project of rural modernisation in the plain. However we managed to solve the problem of drinking water

Der volle Inhalt der QuelleIn China, the phenomenon of new construction is increasing since the end of 1990s and it raises the question of the implications and the consequences of urban modernization, on the life of people. Questioning locally this process, this research is mainly the result of an investigation conducted in the city of Harbin, which is located in the northeast of China (Heilongjiang Province). Then this is a comprehensive ethnography of a community who lives in the “Guxiang“district, in the western part of the city. The renovation of the district activated anxiety and fear in the community and, in this context, conflicts and negotiations between residents and authorities had appeared. Their eviction and of the dwellers movement have follow the destruction of the houses. After that emerged nostalgia and mourning and it express the symbolic character of the transformation which strikes their lifestyle. So, when they come back, the residents try to re-appropriate the new houses and the redrawn space with the need to operate the synthesis between their past and their future on this territory
Lefort, Julie. „Contact de langues dans le Nord-Ouest de la Chine : le cas de Dongxiang“. Paris, EHESS, 2012. http://www.theses.fr/2012EHES0113.
Der volle Inhalt der QuelleDongxiang language is spoken by about 300 000 people mainly living in Dongxiang Autonomous District in Gansu Province, situated in Nord-West China. This language is surrounded by other languages which are originally from different linguistic groups (namely Chinese, Tibetan, Turk and Mongolic). All those languages have highly influenced each other, and the dongxiang language has particularly been influenced by the Linxia Chinese dialect. The geographic isolation of the population and their will to stay away from none Muslims communities has led to exclusive contact between those two languages for a very long period of time. This stable sociolinguistic situation is now destabilized by the new economic development occurring in whole China for nearly twenty years, and therefore, new population and language contacts are occurring today. In this study, I have explained the nature of those changes through sociolinguistic analysis and linguistic description. I have started by analyzing the balance of languages in this particular sociolinguistic situation which has led us to conclude that the community of Dongxiang was not in a situation of diglossia. Through the description of those sociolinguistic changes, I have shown that the dongxiang language has been influenced by Chinese dialects in two phases. During the first phase, it has been exclusively influenced by the Chinese dialect of Linxia and then, other Northern dialects such as Lanzhou’s dialect and Putonghua have started to influence it as well. In the linguistic description part, I have analyzed phonological and lexical elements that have been influenced by Linxia’s dialect. I have then tried to describe how northern Chinese dialects are influencing the dongxiang language through the development of calques and in particular resultative and directional verbal structures. Then I have described the use of Chinese particles and markers de ???? which has appeared in very recent years and are more or less integrated in the language. We have concluded that the Chinese Northern dialect of this recent period have influenced and is still influencing the dongxiang language on a syntactic level, therefore, this kind of influence suggests that more changes will occur under the growing influence of those newly introduced varieties

Der volle Inhalt der QuelleBeyond the conventional historiography which has viewed the relationships between the communist movement (modern revolution) and the secret societies (traditional rebellions) in terms of continuity or discontinuity, this study contextualizes the question of these relations in a compared micro-historic perspective centred on two regions showing sharp contrasts as regards social-rural patterns, the structures of the secret organizations and the activities of the Communists before the early 1940s. In the Shaan-Gan-Ning region, the Gelaohui (Brothers and Elders) play an important part from the first phase of Communist implantation before the Long March (mid 1930s). In the following years, they are politicized by the party center and integrated into the territorialized Communist system. In spite of multiple frictions, party power supervises their activities instead of forbidding them. On the other hand, the Xiaodaohui (Small Swords) in Northern Jiangsu do not respond to Communist mobilization attempts either before the collapse of the First United Front (1927) or later. They appear as local self-defense groups which confront the central Guomindang government during the 1930s, the Japanese occupation forces and the Communist armies during the 1940s. As a result, CCP guerrilla initiatives rely on military factors. As CCP power becomes stronger in the late 1940s, the Small Sword groups are suppressed in spite of many local rebellions. The dissertation thus illustrates the diversity and variations both in time and space of the relations between the secret societies and the Communists. In line with several recent works, it also emphasizes the fact that Communist policies did not stop developing and adjusting locally all along the revolutionary process, although a similar logic of inclusion and exclusion of various social forces was at play in what comes to light as a well engineered state building process

Der volle Inhalt der QuelleThe region of Annaba, situated in the North East of Algeria, contains in its underground water resources that represent a significant enough interest to feed people, water for agriculture and industry. This site is currently undergoing a gradual anthropogenic pressure becomes worrisome. Indeed, the continuous operation of the water has caused deterioration of water quality and negatively influenced the hydrodynamic equilibrium of the aquifer. It has also ensured the emergence of salt wedges even threatening in the short term and exploitation of the water and the proper functioning of wetlands.Based on the analytical results obtained for series of samples of more or less regular intervals, performed on the main measurement networks, we tried to identify key factors influencing the evolution of the physico-chemical water and delineate the advancing salt wedge. In this research, simulation models have proved to be very powerful tools to understand the hydrodynamic functioning of aquifers in the region of Annaba, situated north east of Algeria, taking into account the heterogeneity of environments. They have also highlighted a vulnerability of aquifers in coastal areas where there is inflow of the sea and stream chloride concentration large enough. The negative impacts on groundwater and ecosystems can become catastrophic if nothing is done to curb the problem.Models based on artificial neural networks have emerged as a powerful way to develop predictive relations between the different indicators of the management of water resources in the region. In this context of strong demand for water, only an integrated approach offers the possibility to manage these resources while respecting the natural environment, citizens' interests and those of economic actors. The research meets this need for integration, since the location and evaluation of groundwater resources, to protect their quality, but while evaluating the potential adverse effects. In this research, a new model of integrated management of water has been developed based on the relation of cause and effect addressing the entire cycle of water. Hydrological variables were developed and classified into five categories which are socio-economic constraints of pollution, water quality, impact of human activity and management of urban space and agriculture. The relevant variables were characterized using artificial neural networks, risk assessment on human health and the expert opinion. It has been demonstrated that a combination of practical measures necessary to ensure the sustainable management of water

Der volle Inhalt der QuelleThe postmodern urban condition cannot be approached today without addressing the question of nature in its broader sense and more specifically with regards to contemporary urbanity. It seems in fact that the object, the nature and the content of these concepts of urbanity and nature are being relaxed and enlarged to give birth to new ways of life combining the qualities of the city and the countryside. The progressive elimination of distinction between city and countryside which took place during the second half of the twentieth century led our massively urban post-industrial societies to construct a new relationship with the surrounding environment. From urban nature to new forms of countryside urbanities, from environment to patrimonial nature, the question of urban sprawl as weil as new ways of conceptualizing the city in a durable fashion is at the heart of fundamental social debates. Three civilizations are approached here within their identity and historical perspectives, both contemporary and future, with regards to this relationship between nature and urbanity. These three societies, the European, the North American and the Chinese, were chosen in their capacity as well-known references when it comes to landscape, especially with respect to the city. Our analysis is comparative to European and North American traits. With China, it is also enriched with a look from a distance, in order to enlarge the analysis of the urban postmodern condition in the West with the effect of a detour. Beyond the territorial question, a social question is asked today in an exacerbated manner which touches on the very foundations of our modern civilizations
Li, Jun. „Détection de la transition démographique agricole en Chine : sur le plateau de Lœss et dans la plaine du fleuve Yangszé“. Thesis, Paris, EPHE, 2015. http://www.theses.fr/2015EPHE3029/document.
Der volle Inhalt der QuelleIn this thesis, we study the process of the demographic change during the transition from the hunters-gatherers to the farmers on the Loess Plateau, which is the region of the origin of the cultivated millet, and in the Yangtze Plain, which is the region of the origin of the cultivated rice, in China. By collecting and analyzing the paleoanthropological data from the cemeteries of prehistorical hunters-gatherers and farmers of these two regions in China, we detect a similar signal of the ADT. This signal is also confirmed by the archaeological data, such as the density of the archaeological sites and the density of the radiocarbon dates. We represent the environmental context of the signal demographic in the following study, including the climatic change and the variation of le landscape. The improvement of the natural environment during the demographic transition is obvious, but it seems that this improvement is not a factor decisive of the ADT. Then we represent the change of subsistence strategy of the population from upper Paleolithic to Neolithic in the two regions, and its relationship of reciprocal causation with the demographic transition. The archaeological data indicate that the demographic transition and the change of the subsistence strategy were evidently followed by the modification of the habitation, and the arrangement of the villages have also varied overtime. These information probably suggest that the augmentation of the size of population is one of the main causes of the social evolution
Shi, Xiao. „Fossil plants and environmental changes during the Permian-Triassic transition in Northwest China“. Thesis, Paris 6, 2016. http://www.theses.fr/2016PA066588/document.
Der volle Inhalt der QuellePermian-Triassic transition is an important period in the Earth’s history. The end-Permian mass extinction is the Earth's most severe known extinction event. Previous studies mainly focused on the biotic events in the ocean. Recently more and more researches on the terrestrial events during the Permian-Triassic transition attracted many attentions. The Junggar and Turpan basins of Northwest China command a unique and significant position in the study of terrestrial Permian-Triassic boundary (PTB) events as it contains well and continuously exposed PTB sections. The lithostratigraphy, biostratigraphy, and cyclostratigraphy have been well established in the two basins. The problem we are trying to solve, based on paleobotanical studies associated with sedimentological analyses, is the environmental changes during the Permian-Triassic transition in the research area.The terrestrial facies in the Dalongkou section on the south flank of Junggar Basin and the Taoshuyuan section on the north flank of Turpan Basin have been selected as the researching ones for this thesis. The Permian-Triassic transition strata have been included in the “Wutonggou”, “Guodikeng” and “Jiucaiyuan” formations. Abundant fossil woods and plant impressions have been discovered and collected in these sections. Detailed sedimentary logs of the sections were drawn. The approach that we adopt to recognize the environmental changes is the fossil wood and plant impression species, growth-ring pattern, and sedimentary facies analysis.Five genera and six species of fossil woods were discovered. We establish three new genera: Junggaropitys, Xinjiangoxylon and a new genus (submitted for publication). The CSDM (Cumulative Sum of the Deviation from Mean diameter) curve was used to analyse the growth rings to determine the intraseasonal conditions and leaf longevity patterns of the trees. We recognise that Junggaropitys dalongkouensis is evergreen, and the leaf longevity may be 3–6 years; XTT-C-4 gen. et sp. nov. is evergreen too, and the leaf longevity may be 3 to 15 years. Septomedullopitys, Junggaropitys, Xinjiangoxylon and XTT-C-4 gen. nov. all show a Protophyllocladoxylon-type secondary xylem. According to palaeobiogeographic analysis, the Protophyllocladoxylon-type woods distributed mainly in the cool temperate climate zone of the southern hemisphere, various climate zones of the northern hemisphere and equatorial zone during the Late Paleozoic. The results of fossil woods analysis obtained in this research shows the climate in the Junggar terrane around the PTB was warm and humid and the temperature and precipitation remained relatively stable. It did not exist a heavy dryness in the earliest Triassic. Meanwhile, the Palaeo-Tethys megamonsoons did not influence the Junggar terrane along the east coast of mid-latitude Pangaea. Combined with the previously reported fossil woods, it shows that the climate had no prominent change from the Middle Permian to earliest Triassic.Plant fossil analysis show that the numbers of plant genera and species gradually decreased from 26 genera and 53 species in the Wuchiapingian, to 10 genera and 15 species in the Changhsingian, and only 6 genera and 7 species in the Induan. The trend in the plant assemblage reduction in the Junggar and Turpan basins appears to be indicative of a long, protracted extinction process that may have started well before the Permian-Triassic boundary. During the plant recovery period, the lycopsids (Annalepis) and ferns (Neocalamites and Pecopteris) played roles of pioneer species during the plant recovery period
二叠-三叠纪之交是地球历史上的关键时期。发生在二叠纪末期的大灭绝事件是最严重的生物灭绝事件。前人对此次灭绝事件的研究主要集中于海洋生物的变化,近年来越来越多的研究开始关注于这一时期陆地生态系统的变化。 位于中国西北部的准噶尔盆地和吐鲁番盆地出露了完整的陆相二叠-三叠系界线附近地层,因此在这一研究方面具有独特的优势。前期研究中在这一个地区建立了良好的岩石地层,生物地层和旋回地层格架。本文将集中解决二叠-三叠纪之交研究区的环境变化问题。我们选择了位于准噶尔盆地南缘的大龙口剖面和吐鲁番盆地北缘的桃树园剖面,两个陆相地层剖面作为论文的研究对象。在这一区域,二叠-三叠系之交地层是由梧桐沟组,锅底坑组和韭菜园组组成。我们在大龙口剖面和桃树园剖面二叠-三叠系地层中发现了大量木化石和植物印模化石,对剖面绘制了详细的地层柱状图。我们鉴定了木化石和植物印模化石种属,木化石年轮类型,分析了沉积相变化,进而用来识别研究区的环境变化。 我们对所采集到的130块木化石进行了切片,通过生物显微镜对其解剖结构进行研究,共发现了木化石5属6种,包括建立的三个新属:Junggaropitys,Xinjiangoxylon和 XTT-C-4 gen. nov.(还在审稿中)。这三个属均具有内始式的初生木质部和Protophyllocladoxylon 型次生木质部,其中Junggaropitys具有同质但异细胞的髓部;Xinjiangoxylon拥有具薄壁细胞和分泌管的髓部;XTT-C-4 gen. nov.的髓部中具有独特的板状支撑结构。我们应用CSDM曲线(平均值偏差累计曲线)分析木化石的年轮用以识别其生长季的条件和叶的寿命。CSDM曲线分析表明Junggaropitys dalongkouensis为一种常绿植物,叶的寿命为3-6年;XTT-C-4 gen. et sp. nov.也为常绿植物,叶的寿命3-15年。Septomedullopitys, Junggaropitys, Xinjiangoxylon和XTT-C-4 gen. nov.四个属的木化石均展示出Protophyllocladoxylon型次生木质部。我们对晚古生代全球发现的具有Protophyllocladoxylon型次生木质部的木化石进行了生物古地理分析,我们发现,在晚古生代,具有Protophyllocladoxylon型次生木质部植物,在南半球仅分布在冷温带地区;而在北半球和赤道地区,其分布在不同的气候带。对木化石的分析显示准噶尔地块在二叠-三叠系界线附近古气候温暖湿润,温度和降雨量相对稳定;古特提斯洋巨季风没有影响到东岸的泛大陆中纬度地区。结合前人对这一地区其他木化石研究,我们认为研究区的古气候自中二叠世至早三叠世早期没有显著的变化。植物化石分析显示,植物种属由吴家坪期的26属53种逐渐减少到长兴期的10属15种再到早三叠世印度期的6属7种。在准噶尔盆地和吐鲁番盆地,二叠-三叠系之交,植物显示了一个长时间的逐渐灭绝的过程。通过对比白垩纪-第三纪植物灭绝事件和现代恶劣环境下植物恢复的实例,我们发现石松类(脊囊属)和蕨类(新芦木属和栉羊齿属)在植物复苏阶段扮演着先驱分子的角色。我们对大龙口剖面,桃树园A和C剖面进行了沉积相分析。在大龙口剖面我们识别出4个主要的沉积相。梧桐沟组上部主要由辫状河相,短暂的河流系统或湖和冲积平原相组成。锅底坑组为湖(或池塘)相和洪泛平原相沉积。韭菜园组主要由冲积平原和湖(或池塘)相沉积组成。在桃树园地区,梧桐沟组上部至锅底坑组底部的一套地层主要是湖(或池塘)相和洪泛平原相沉积。锅底坑组下部为一套辫状河沉积。而锅底坑组上部为冲积平原和湖(或池塘)相沉积。韭菜园组主要为辫状河和洪泛平原沉积。对碎屑岩的样品岩相学分析显示跨越二叠-三叠系界线,沉积物物源一致。其中火山碎屑物来源于多个火山源。大龙口剖面和桃树园剖面在界线附近沉积物的物源保持一致,这说明,这两个剖面在二叠-三叠系之交时期处于同一个盆地,而博格达山隆起晚于这一时间。灰岩样品指示了湖泊环境的沉积。二叠纪末期的植物灭绝降低了河岸的强度,增加了坡地的沉积物的提供,进而增加了河道中沉积物的卸载。这导致了研究区在吴家坪期和长兴期界线附近和早三叠世的两次沉积相的改变。

A regional synthesis is proposed for an area including the southern half of the rhine "graben" and the north of the french historical province franche-comte. After a reapraisal of the chronological frame, the different cultures are examines under the points of view of settlement system, settlement, funera practices and communications networks as revealed by the circulation of some prestige goods. In the part concerned with early neolithic, a chapter is devoted to the non linear components with meridional affinities (limbourg and hoguette ceramics). The local evolution is then confronted with the general evolution in the danubian sphere, with particular insistance on the problem of social organisation

Der volle Inhalt der QuelleAny language in the world evolves according to internal and external mechanisms which are specific to each language. Our work focuses on these factors, and particularly on the effects of contact between different languages. Researchers have highlighted these linguistic interactions and showed that all kinds of linguistic elements can be transferred from one language to another. The Altaic language family in China includes languages of the three main branches (Tungus-Manchu, Mongolian, and Turk), which have been more or less in contact with Chinese. In this work, we study Khorchin (qorcin, ch. keerqin), an Eastern Mongolian dialect that has been in contact with Chinese significantly in time and space. Linguists from Inner Mongolia have noted the phenomena of " language mixing" in Khorchin, revealing a considerable amount of loan words from Chinese. This work attempts to show, through a phonological, morphological and syntactic description, some linguistic phenomena that are specific to this dialect. To understand the mechanisms involved and identify internal and / or external factors, this description relies on a comparison between the Khorchin and other Mongolian dialects, and in particular Oirat.

Djamouri "Language contact and language change: the case of Chinese and Altaic languages", and by Ms. Dan Xu, "Do languages and genes correlate? - A case study in Northwestern China "

Der volle Inhalt der QuelleChina’s “energy diplomacy” has been the subject of much debate and controversy ever since the country became a net oil importer in 1993. Observers and analysts watched with unease as Beijing appeared to be unleashing its National Oil companies (NOCs) to compete for global oil resources and lock them up for China’s own use. China’s diplomacy has been said to be put to the service of its energy needs and ever since 1993 and oil supply security was deemed to be the utmost objective of foreign and strategic policy. This dissertation aims to challenge that view and to provide a new way of analysing the interactions between energy and diplomacy in China. It posits that the country’s overseas energy activities in the early 1990s were not the outcome of a comprehensive, rational plan devised in Beijing but rather the result of a series of incremental and disjointed policy steps taken by different actors, each pursuing their own goals and interests. It is the aim of this study to analyse how this energy diplomacy evolved by looking at the actors shaping it and the interactions between them: how did China’s overseas energy activities come about? What were their implications for China’s diplomatic strategy in the Middle East? How, and when, did oil security reach the top of the policy making agenda and what have been the main features of the policy process, from agenda setting to implementation? Is there a “Chinese grand strategy” for locking up oil? What are the tensions underlying China’s oil diplomacy?

Der volle Inhalt der QuelleOur aim is mapping palaeochannels on the archaeological site of Aquileia. A multicriteria approach based on bio-morphosedimentary data and imagery analysis allowed us to draw the map of the hydrographical network during Roman antiquity. In the plain of Aquileia, several alluvial ridges were reconstructed from the interpretation of a DTM and a Landsat false colour composition. On the archaeological site, riverbeds were extracted from a composition Landsat of 3 neo-canals elaborated with a NDVI algorithm, which sorts out various degrees of soil moisture. Then palaeo-riverbeds were validated by a high-resolution laser DTM, by tomographic data and by sedimentological and palaeontological analyses of deep cores. Un the end, we retrieved the Isonzo paleoridges which spread out on its megafan and its ramifications increase with each floodplain break slope. One of them reaches Aquileia, but the antique harbour was crossed by the Torre alone. The river and its tributary had indeed undergone a diachronic evolution versus east. On the harbour itself, the chronostratigraphic datas showed that the River was active until II c. AD. Then it turned into a small river, the Natissa. In order to going on with the traffic, Romas performed the narrowing of the channel. The area is now abandoned till the II c AD

Der volle Inhalt der QuelleOver the past decade, the Little Bahamas Bank (LBB) in the Caribbean has been at the heart of oceanographic cruises Carambar (2010), Caramba 1.5 (2014) and Carambar 2 (2016-2017). These scientific expeditions were carried out with the aim of improving our knowledge of the processes tha controlled sediment export during the Quaternary in this tropical setting. Thus, bathymetric datacovering some 24,270 km² of seabed, high-resolution seismic lines running over 6,398 km and 42sediment cores ranging from 177 to 4,873 m water depth were collected in the upper slope through tothe abyssal plane of the LBB system.This study focusses on those sediment cores retrieved in the upper (Carambar 1.5) and lower slope ofthe LBB and those from the Great Canyon (Carambar 2) which is connected to the abyssal plane. These results are complementary to previous studies led on the middle and lower northern slope of the LBB (Tournadour, 2015; Chabaud, 2016).A highstand accretion wedge, currently dated to the Holocene, expands at water depths of 177-360 m. Sediment deposition in the prism is mainly the result of hurricanes and density cascading. Its initiation is dated at 13. 6 ± 3.5 ka cal BP, following Meltwater Pulse 1A. Melwater Pulses led to the formationof shallow terraces that enhanced carbonate production and ultimately supplied the prism with sediment through the export of said carbonate. The height of the development of the prism occurred at 6.56 ± 0.9ka cal BP when the sea level reached the shelf-break.Sedimentation in the lower slope is indicative of more pelagic processes, since currents play a greater part in the deposition of sediment than the shelf. Variability in the facies of theses deposits are thus the result of climatic variations (e.g strengthening of currents, influxes of Arctic water). Sediments in this are a share similarities with those in Blake Outer Ridge, 400 km north of the LLB. At water depth of1,300-4,800 m, the slope is scored by a giant canyon, namely the Great Abaco. The morphology of this canyon attests to a structural control of sediment supply: rather than the head of the canyon, tributaries appear to supply the majority of sediment within this system

Der volle Inhalt der QuelleThis research concerns the emergence and the decline of the “escort-masters”, biaoshi 镖师, as well as the evolution of their practices in relation to the trading world of Northern China (18th early 20th). The escort-masters were organised around private societies called “escort companies”, biaoju 镖局. They were responsible for the transport of goods (for ex. money (tael), salt, silk, tea). They were also in charge of protecting the traders, who were victims of plunder from brigands during their journeys. These traders came from Shanxi Province and are called Jinshang 晋商. The escort companies were structured around the transmission of clannish alchemical, ritual and martial traditions still transmitted and practised in present-day. For this reason, these practices are, in my dissertation, the subject of an in-depth study. One of the main lineages involved in the biaoju was the tradition xingyiquan 形意拳 (“Form-Mind [combat] Techniques”) created by Shanxi escort groups in the second part of the 19th c. The description of the interactional logic between the groups concerned may reveal new fields of understanding about the phenomenon of escort companies. In addition, it may reveal how the evolution from caravan convoys into guarding residences activities has played a key role in the process of transforming techniques and modes of transmission. The combination of the ethnographic method (testimonies), archival research, as well as an analysis of primary and secondary textual sources (including narratives), gives this study a historical and social depth, which should help shed new light on the relationship between Shanxi local ritual and martial traditions, brigandage and trade

Der volle Inhalt der QuelleThe enactment of the 3 October 1965 Immigration Law has triggered off new Chinese migrations to America based on skill and family reunification. The flows of Chinese students between the Chinese world and the United States underscore the challenge that education and the training of skills mean in the context of a globalized knowledge-economy at the dawn of the 21st century. The brain drain to the United States and the brain gain of the Chinese world has produced a win-win process encouraged by both the American and Chinese leaders within the framework of a technopolitan “archipelagoes” economy during the 1965-2005 period in the “relational age”. The new Chinese immigration wave numbered some 200 000 doctoral-level people at the beginning of the 21st century. In addition to the new immigrants scientific skills one has to consider their professional and social networks in Asia as well as in America. Thus about a third of Silicon Valley businesses originated in Chinese or Indian immigrant entrepreneurship in 2005. Indeed northern California has looked attractive to the new Chinese immigrants, owing to its network of universities, culture of innovation, start-ups incubators, tireless search for new markets around the Pacific Rim, and the fact that more than half of Chinese-American families lived on the West coast according to the 2000 Census. This new Chinese immigration is tempted by two logics: the universal concept of “Cultural China,” which spawns a diasporic Chinese identity, and Americanization, which tends to American Assimilation

Der volle Inhalt der QuelleL'objectif des travaux présentés dans ce mémoire est, par une approche sédimentologique, de reconstituer les conditions environnementales, tant sur les continents que sur les plates-formes, ayant conduit aux dépôts étudiés. Sur cette base, nous avons entrepris des études sur des dépôts du Pléistocène en mer du Nord ainsi que dans les mers de Chine de l'Est et du Sud. Cette époque, par sa proximité, permet des études à très haute résolution temporelle tandis qu'elle est caractérisée par des oscillations climatiques et eustatiques importantes et rapides. De plus, les dépôts les plus récents portent la trace de l'Homme.
Sur la plate-forme, l'étude des grands corps sableux, bancs et très grandes dunes, a permis de préciser les mécanismes de leur mise en place. A court terme, même dans les environnements dominés par la marée, l'importance de phénomènes sporadiques tels que les houles de tempêtes, a été démontrée. Ils impriment aux formes et à la structure des fonds marins leur marque tandis que les agents tidaux sont les pourvoyeurs du matériel sédimentaire. A plus long terme, ce ne sont plus les agents dynamiques qui conditionnent la préservation des corps sédimentaires mais la création d'espace disponible et l'importance des apports sédimentaires. Au niveau de l'estuaire de l'Authie, des séries de carottages nous ont aidé à mesurer les conséquences du mouvement vers le nord des divers ensembles sédimentaires sur le type de sédiment rencontré ainsi que sur les modifications d'un espace naturel convoité par l'Homme.
Dans les bassins profonds, en mer de Chine du Sud, nos études ont permis de préciser les sources du matériel sédimentaire et son transport en faisant la part des contributions éolienne, fluviatile et marine. L'étude des caractères sédimentologiques de la fraction détritique a permis également d'étudier la balance ntre l'érosion et l'altération sur les zones émergées ainsi que de voir quelle est la réponse des marqueurs détritiques aux changements climatiques globaux depuis 2 millions d'années.

Der volle Inhalt der QuelleThis study is performed to investigate the question of bone industry in the North-West of China. Basically, it has been forgotten by researchers for a while. Likewise, the aim of the study is to make it clear for researchers in who are interested. The content of Gansu, Qinghai and Ningxia, is emphatically implement principal periods of Neolithic later to Bronze Age early time transformation, which is equivalent to somewhere between 3100 BC and 1600 BC. Also, it attempts to highlight the choices of the raw material, the manufacture methods, the evolution, the distribution, and the diffusion of the objects Majiayao and Qijia Culture. Basically, the approach is to find the interactions among the human beings, tools and the cultures. Firstly, the aim is to deal with the techniques of manufacture and the morphology as for bone industry. Initially, we will present the archaeological contexts in the North-West of China, and then classify the parts according to their functions in three categories: production equipments (hunting, fishing, breeding and agriculture), tools for daily or domestic use, and ornaments. Afterward, we will try to analyze the characteristics of the objects as well as their contribution for the knowledge of the prehistoric economy. Finally, we will concentrate on regional specificities starting from some sets of themes, the arrowheads, the shovels, the objects composite, the "cover", the plates, and the arm-bands. We will have the results obtained from the archaeological points of view regarded as the starting point of a wider reflection

Der volle Inhalt der QuelleThe aim of this study is to reconstruct late Quaternary environmental changes in the northern South China Sea by applying multi-disciplinary proxies of land-sea interaction, East Asian monsoon, and oceanic circulation. Investigations of clay and magnetic mineralogy, major element composition, and grain size were performed on marine sediment Core MD12-3432 retrieved from the continental slope of the northern South China Sea. The core covers the last 400 ka with a sedimentation rate varying between 4.5 and 24 cm/ka. We examined the accuracy of existing calibration methods on major element composition obtained by XRF core-scanning, because downcore variations in interstitial water content should strongly affect scanned element contents. We proposed a quadratic polynomial correction to account for this effect and implemented it in the calibration methods. Data from Core MD12-3432 show that the improved calibration process now correctly converts XRF core-scanning data into major element concentrations. Our results on high-resolution major element composition, clay and magnetic mineralogy, and grain size data indicate that low-latitude climate changes influence various terrigenous fractions in different ways. In bulk sediment, K₂O/Al₂O₃ ratio mainly reflects the relative contribution of detrital supply from Taiwan, and its variation exhibits eccentricity cycles. The ratio increases during interglacials, showing that strong precipitation and denudation are induced by enhanced East Asian summer monsoon. In clay fractions, smectite/(illite+chlorite) ratio presents both eccentricity and precession periodicities, in phase with the northern hemisphere summer insolation changes and therefore with the East Asian summer monsoon evolution. Based on the knowledge of sediment provenances, these results suggest that high smectite/(illite+chlorite) ratios illustrate contemporaneous chemical weathering intensity in Luzon. It supports the understanding that East Asian summer monsoon is enhanced during interglacial periods and when the boreal summer insolation is strong. Therefore, these two ratios are appropriate sedimentary tracers for East Asian summer monsoon evolution in the South China Sea. The magnetic fraction yields complementary information about environmental changes in the South China Sea. The magnetic mineral assemblage of Core MD12-3432 is mainly composed of magnetite, sulphide, and hematite, and the relative contributions of all these magnetic mineral contents change with time. Variations on precessional band related to the low latitude East Asian monsoon are observed in magnetic properties and grain size values. High magnetic inputs with high hematite proportion, which is part of fine-grain sediment, are observed during the precession minima. These events occurring during arid periods may illustrate enhanced eolian inputs caused by changes in intensity and/or winds pathway of winds, probably related to enhanced winter monsoon. Besides the low-latitude climate changes, global climate and tectonic activity also influence the terrigenous composition at the studied site at different timescales. A long-term increase in pyrrhotite content with respect to magnetite and hematite and in illite/chlorite contents indicates an increasing contribution of fine grained sediments from Taiwan. This is most likely related to the intensification of Taiwanese orogeny over the last 400 ka. On glacial-interglacial scale, coeval increases observed in sedimentation rate, magnetite/pyrrhotite content, kaolinite content, and grain size during glacial periods are attributed to sea-level changes. Low sea-level during glacial periods exposes the vast shelf and allows the Pearl River to deliver more and coarser terrigenous sediments to our site
