Abstract:
In addition to agriculture, the water–land nexus (WLN) also profoundly affects the sustainable development of industry and residents’ lives. However, little research has been designed to assess the water–land nexus from the perspective of industry development and people’s quality of life. In the current paper, Wi, a regional industrial water–land nexus matching index, and Wd, a matching index of the domestic water–land nexus, were proposed for evaluating the water–land nexus from the industry development and quality of life perspectives separately in the current paper. Furthermore, climate change and human activities have significant impacts on the water–land nexus. The WLNs were assessed spatially and temporally for the first time based on these two indexes in 128 municipalities in the Huang-Huai-Hai River Basin of China from 1951 to 2017 to analyze the impacts of the changing environment on them. The impact of changing environment was explored based on changes of some climate factors and land use. The value of Wi are higher in the eastern and southern cities than the western and northern cities, while Zhenjiang city in Jiangsu Province has the highest Wi. For Wd, there are two low Wd zones across the basin, while the minimum values occurred in Linxia Hui Autonomous Region (Wd = 35.34 mm). Wi and Wd in most cities in the basin showed a significant downward trend, and some cities in the southwest of the basin have the fastest-decreasing of Wd. Wt and Wa were also calculated to assess the total and agricultural water–land nexus separately based on existing research. The Wt for the Huang-Huai-Hai River Basin gradually increases from northwest to southeast, and its spatial distribution characteristics are similar to precipitation in the river basin. In addition, the government should simultaneously implement water transfer plans to reduce the agricultural water pressure in Ningxia and Gansu provinces. Dynamic driving factors of change of the four assessment indexes (Wt, Wa, Wi, Wd) are briefly analyzed in the end of the paper.

Abstract:
Dynamic change of groundwater storage is one of the most important topics in the sustainable management of groundwater resources. Groundwater storage variations are firstly isolated from the terrestrial water storage change using the Global Land Data Assimilation System (GLDAS). Two datasets are used: (1) annual groundwater resources and (2) groundwater storage changes estimated from point-based groundwater level data in observation wells. Results show that the match between the GRACE-derived groundwater storage variations and annual water resources variation is not good in six river basins of Northern China. However, it is relatively good between yearly GRACE-derived groundwater storage data and groundwater storage change dataset in Huang-Huai-Hai Plain and the Song-Liao Plain. The mean annual depletion rate of groundwater storage in the Northern China was approximately 1.70 billion m3 yr−1 from 2003 to 2012. In terms of provinces, the yearly depletion rate is higher in Jing-Jin-Ji (Beijing, Tianjin, and Hebei province) and lowest in Henan province from 2003 to 2012, with the rate of 0.70 and 0.21 cm yr−1 Equivalent Water Height (EWH), respectively. Different land surface models suggest that the patterns from different models almost remain the same, and soil moisture variations are generally bigger than snow water equivalent variations.

Doan Nguyen Tuan, nick name Hai Ong, Hai Yen village, Quynh Coi district (now known as Hai An village, Quynh Nguyen commune, Quynh Phu district), Thai Binh province. He had Huong sewer following the Le Dynasty but did not work as mandarins, with Vu Huy Tan, Phan Huy Ich, Ngo Thi Nham..., he followed Tay Son. By the concept of flexible museum, Doan Nguyen Tuan pursued and persevered the path of religious practice in the disordered social condition. With more than 200 Han poems still left, Doan Nguyen Tuan had the opportunity to show quite clearly the important aspects of the content of the thought of his practice. Thus, it can be affirmed that he is one of the authors of fictional literature in the second half of the eighteenth century in particular, of Vietnamese literature in general. This is the main content we set out and solved in this article.

Abstract:
SUMMARYIn order to study pollen-mediated gene flow in transgenic maize (Zea mays L.) in the Huang-huai-hai region of China, field trials were conducted in Jinan, Shandong Province in 2006 and 2007. The frequencies of gene flow from the donor plots, planted with transgenic maize as a pollen source, to the receptor plots, planted with non-transgenic maize, under different temporal or spatial separations were evaluated. The results showed that the frequency of pollen-mediated gene flow of the als gene from transgenic maize to non-transgenic maize decreased significantly with increasing distance. No gene flow was detected at 300 m. At a distance of 30 m, delaying the planting date of the transgenic maize by 1 week decreased the frequency of gene flow by 70%. A delay of 2 weeks decreased the gene flow frequency by more than 90%, while no gene flow was seen when the sowing date was delayed by 3 weeks. The results suggest that an appropriate isolation distance of 300 m or a temporal separation of 3 weeks could prevent gene flow from transgenic maize to non-transgenic maize in the Huang-huai-hai region.

Abstract:
The Northern key economic region, which includes Hanoi, Vinh Phuc, Bac Ninh, Quang Ninh, Hai Duong and Hung Yen, is the main centers of Vietnamese politics, economics, culture and science and technology. This region has many advantages in terms of economic exchange and international integration. In the period of 2010 - 2018, the region has really become a reliable destination for domestic and foreign investors, attracting increasing investment capital, especially foreign direct investment (FDI) in the manufacturing industries. Thanks to FDI in industry, the growth rate of gross output is the highest among 4 key economic regions; changing industrial structure (emerging electronics, informatics, manufacture mechanics ...); ownership structure (the FDI sector ranks first with 4 key economic regions) and territorial structure (industrial production value of Bac Ninh province has surpassed that of Hanoi city, leading the whole Northern key economic region). The paper focuses on analyzing FDI in industrial development and its role in socio-economic development of the Northern key economic region in the period of 2010-2018.

Abstract:
Leptobrachella shiwandashanensis was originally described from the evergreen forest of Mount Shiwandashan, Guangxi province, China. We herein record this species for the first time from Vietnam based on a new amphibian collection from Quang Son commune, Hai Ha district, Quang Ninh province. Morphological characteristics of the specimens from Quang Ninh province, Vietnam resemble those of the type series from China in the following characteristics: small size; head wider than long; pale brown dorsal surfaces, with distinct dark brown inverse-triangle-shaped marking between eyes; flanks with irregular black spots; ventral surface creamy white with brown spots on lateral margin; throat and chest nearly immaculate creamy white; fingers and toes free of webbing; dermal fringes on sides of fingers and toes absent; tibio-tarsal articulation reaching to posterior of the eye; iris bicolored, upper half brownish-red, transitioning to silver in the lower half. However, the specimens from Vietnam slightly differ from the type series from China by having a smaller size in males and a somewhat different dorsal colour pattern in the female. Genetic divergences between sequences of the Vietnamese specimens and those of L. shiwandashanensis from China are approximate 1.7–1.9% (16S gene). In addition to our morphological and molecular comparisons, we provide first natural history notes of L. shiwandashanensis from Vietnam.

Abstract:
A research on zoobenthos biodiversity was carried out from September 2004 to September 2006 at the Ca river (the length of Nghe An and Ha Tinh provinces) showed a species composition consisted of 154 species, 115 genera, 72 families, 32 orders and 5 phyla, including Mollusca, Annelida, Arthropoda, Echinodermata and Sipuncula. The results showed that a decreasing trend in the number of zoobenthos species from the fresh water area to the estuary of the Ca River. The largest number of species was shown in route 1 (Cua Hoi) with 89 species (nearly 44.7%). The lowest value of species number was seen at route 5 with 31 species (15.5%). The Crustacea group was the most predominant group, including 47 species. The H' and d indexes indicated a decreasing biodiversity level from route 5 (Hung Lam, H' = 0.9 and d = 0.75) to route 1 (Cua Hoi, H' = 2.32 and d = 1.96). The average number of zoobenthos density was 149 individuals per m2. The average value in dry season was higher than that in rainy season (151 individuals per m2 compared to 146 individuals per m2, respectively). In the dry season, the biological indexes changed mainly according to salinity and turbidity factors. Meanwhile, in rainy season, the variation of zoobenthos species related essentially to other factors, DO and salinity.

Abstract:
Vuong Huu Quang 王有光, with courtesy name Dung Hoi用晦 and poetic name Te Trai 濟齋, was a high-ranked mandarin of the Nguyen Dynasty. He was born in Tan Duc Village, Tan Long District, Phien An Town, Gia Dinh Province, Southern Vietnam, into a family of the Ming-Dynasty immigrants who originated from CangZhou County, Fujian Province. Vuong Huu Quang held many important positions in the imperial court across various localities and traveled to China for diplomatic mission twice in the fifth year of Thieu Tri Emperor (1845) and from the seventh year of Thieu Tri (1847) to the first year of Tu Duc Emperor (1848). His name, however, is unfamiliar to Vietnamese modern readers due to his limited written legacy, most of which was lost in history. Researchers have known of only two steles poems he left in China, one engraved on a stele in Wuxi and the other in the Yue Fei Temple. Upon reading the old collection Viet Nam Han van Yen hanh van hien tap thanh 越南漢文燕行文獻集成, I discovered that Vuong Huu Quang and his co-worker Pham Chi Huong enjoyed writing and responding in poetic form during their diplomatic trips to China. This article introduces several more poems of Vuong Huu Quang to expand our understanding of another Southern Vietnamese poet who have been mostly covered by time, and provides a brief analysis on the poetic style that Vuong Huu Quang and Pham Chi Huong applied in portraying historical figures.

Abstract:
The Yangtze River Delta, located in East China, is an important passage on the eastern pathway of the northward migration of fall armyworm Spodoptera frugiperda (Smith) in China, connecting China’s year-round breeding area and the Huang-Huai-Hai summer maize area. Clarifying the migration dynamics of S. frugiperda in the Yangtze River Delta is of great significance for the scientific control and prevention of S. frugiperda in the Yangtze River Delta, even in the Huang-Huai-Hai region and Northeast China. This study is based on the pest investigation data of S. frugiperda in the Yangtze River Delta from 2019 to 2021, combining it with the migration trajectory simulation approach and the synoptic weather analysis. The result showed that S. frugiperda migrated to the Yangtze River Delta in March or April at the earliest, and mainly migrated to the south of the Yangtze River in May, which can be migrated from Guangdong, Guangxi, Fujian, Jiangxi, Hunan and other places. In May and June, S. frugiperda migrated further into the Jiang–Huai region, and its source areas were mainly distributed in Jiangxi, Hunan, Zhejiang, Jiangsu, Anhui and Hubei provinces. In July, it mainly migrated to the north of Huai River, and the source areas of the insects were mainly distributed in Jiangsu, Anhui, Hunan, Hubei and Henan. From the south of the Yangtze River to the north of the Huai River, the source areas of S. frugiperda were constantly moving north. After breeding locally, S. frugiperda can not only migrate to other regions of the Yangtze River Delta, but also to its surrounding provinces of Jiangxi, Hunan, Hubei, Henan, Shandong and Hebei, and even cross the Shandong Peninsula into Northeast China such as Liaoning and Jilin provinces. Trajectory simulation showed that the emigrants of S. frugiperda from the Yangtze River Delta moved northward, westward and eastward as wind direction was quite diverse in June–August. This paper analyzes the migration dynamics of S. frugiperda in the Yangtze River Delta, which has important guiding significance for the monitoring, early warning and the development of scientific prevention and control strategies for whole country.

Abstract:
Between 1961 and 1976 Häi Hung province -- present day Häi Duong and Hung Yên -- lost the equivalent of two entire districts of agricultural land. How could so much land be abandoned under a collectivised agriculture system? And what role did poor water control infrastructure play in creating such a situation?¶ I answer these questions by examining the historical patterns of hydraulic development in northern Vietnam from the beginning of the 19th century until the introduction of the Production Contract system in 1981. Underlying both the French colonial and communist visions of modernity and economic development was a belief that improving agricultural productivity, of which large-scale hydraulic infrastructure was an important component, could catalyse growth in the rural economy, which could then finance industrialisation. I argue throughout this thesis that developing large-scale hydraulic infrastructure in the Red River delta has relied upon the creation of a hydraulic bargain between the state and water users. This is in contrast to Wittfogel's theory of the hydraulic state, insofar as developing hydraulic infrastructure has depended upon the active political and economic participation and support of water users, and not the absolute power of the state. The political economic history of the hydraulic bargain highlights the relative power of peasants to influence the direction of large-scale hydraulic development and, as such, the shape of the Red River delta's wet-rice economy.
