Testo completoAbstract (sommario):
Meat processing industries produce large volumes of high strength wastewater.
Conventional technologies used in Australia and similar countries for treatment of
effluent from meat processing and similar industries, such as wineries and processed
food industry, are treatment ponds with or without a mechanical treatment system.
A properly designed activated sludge treatment system would be capable of biological
removal of phosphorus and nitrogen in addition to BOD5. These systems, however,
require substantial electrical power, skilled operational support and produce large
quantities of biosolids or sludge which require further on-site treatment or off site
disposal. Application of sub-surface flow constructed wetland (SSF-CW) systems could
provide a sustainable solution for treatment of meat processing industry effluent and
other similar high strength wastewaters. There are, however, only very limited studies
on application of SSF-CW for secondary treatment of high strength wastewaters.
Although there have been a number of cases where SSF-CW have been used as the
secondary treatment unit for municipal wastewater, this technology has not still become
a common practice for the same purpose in Australia. Most of the applications are for
either polishing of secondary or tertiary treated municipal wastewater or for greywater
treatment.
This research was funded by National Meat Industry Advisory Council (MINTRAC).
Sustainable wastewater treatment has been taken up as a very important issue by meat
industry. The industry provides Ph.D research scholarships through MINTRAC to
develop new technologies for wastewater treatment and nutrient removal from meat
processing effluent.
The main objective of the research was to develop process engineering design
parameters for sub-surface flow constructed wetland (SSF-CW) with Monto vetiver
(Vetiveria zizanioides recently reclassified as Chrysopogon zizanioides) as the emergent
vegetation for treatment of high strength, nutrient rich wastewater. The study also
investigated the phosphorus retention properties of pea gravel for use in SSF-CW
system as bed media or as an external phosphorus removal system for meat processing
industry effluent. In addition, chemical methods for phosphorus removal from meat
processing industry effluent were also investigated.
The thesis is based on experimental research. The research consisted of three types of
experimental set up; a) using two laboratory experimental SSF-CW reactors (one with
vetiver grass and the other reactor with no vegetation) in a greenhouse with batch
feeding of artificial wastewater that simulates meat industry effluent, b) experiment with
pea gravel of different particle sizes and solutions of different phosphorus (P)
concentrations in a constant temperature room, c) laboratory experiment using actual
meat processing industry effluent with alum and sodium aluminate for P removal.
The structure of the thesis is as follows. Following the Introduction is the section of
Literature Review, then sections on the experiments that follow a journal paper format,
followed by a General Discussion, Conclusions and Recommendations. A list of
references is provided at the end of the thesis.
The literature review section has four chapters (Chapter 2 to Chapter 5). Chapter 2
describes a review of meat processing industry effluent characteristics and current
treatment technologies. Chapter 3 is a critical review of current literature on COD
removal using sub-surface flow constructed wetlands (SSF-CW). Chapter 4 and 5
describe a review of various processes and models on the fate of nitrogen and
phosphorus in SSF-CW system respectively.
Chapters 6 to 10 deal with experimental research part of the thesis. Chapters, 6, 7 and 8
share a common methodology section which is described in Chapter 6. Results of the
batch experiments with the laboratory SSF-CW systems on COD removal, nitrogen
removal and phosphorus retention are discussed in Chapters 6, 7 and 8 respectively.
Chapter 9 explains a detailed experimental study on phosphorus adsorption dynamics of
pea gravel. Chapter 10 discusses the results on experiments using sodium aluminate and
aluminium sulphate for P removal from meat processing industry effluent as an alternate
P removal method for such effluent.
An overview of the major results of the experimental section is discussed in chapter 11,
in the General Discussion section. Conclusions and Recommendations of the research
are provided in Chapter 12.
In this study, it was observed that Monto vetiver grass performed better during
nitrification than in denitrification, where the plant did not survive. Ammonium N
removal followed a first order decay in both vegetated and un-vegetated experimental
SSF-CW system with average removal ranging from 40 to 60 % of the influent.
Denitrification was found to be the pathway for nitrate removal. As long as the carbon
source was available, the denitrification followed a first order exponential decay, with
over 80% of nitrate was removed in 48 hours. Vetiver grass sustained elevated
ammonium levels of approximately 200 mg/L or more, however it was under stress
during denitrification and it eventually died.
The experimental SSF-CW systems with pea gravel as bed media could effectively
retain soluble reactive phosphorus (SRP) in the wetland cells during experiments of
COD reduction and nitrification (with ammonia and high COD input). However, during
denitrification study, both experimental SSF-CW cells did not show significant removal
of SRP from wastewater. The vegetated cell removed nearly 50% of the input SRP,
however, the un-vegetated cell did not show any trend for SRP removal, and in some
cases the effluent SRP was nearly 90% of the input value.
The role of Monto vetiver grass for N and P removal was found to be very minor and
this study concluded that nutrient removal (N & P) by plant uptake could be neglected
in the design of SSF-CW system with Monto vetiver grass.
Adsorption is the major mechanism for P removal from the experimental SSF-CW
systems, where pea gravel was used as bed media. The P adsorption capacity of pea
gravel increased with decrease in particle size. For 16 to 18 mm, the Langmuir
adsorption maximum was 99 mg/kg, whereas for very fine pea gravel powder (<150
ìm) the maximum adsorption observed experimentally was 3950 mg/kg. In a typical
wetland with pea gravel as bed media for meat processing industry, the media would be
capable of P retention for about 2 to 3 years of operation. Supplementary chemical
removal method is needed for sustainable P removal once the adsorption maximum of
wetland cell is reached.
A chemical P removal system using liquid alum and NaOH for pH stabilisation is more
appropriate than sodium aluminate. Application of sodium aluminate for P removal for
meat processing industry effluent is found to be less effective as it would need higher
dosage, longer settling period, coloured supernatant, acid addition for pH adjustment.
Liquid alum application rate is recommended to be between a molar ratio of Al: P of 3
for TP value of <1 mg/L in the treated effluent.
This research study concludes that horizontal flow SSF-CW system with Monto vetiver
grass is suitable for COD removal and nitrification from high strength wastewater.
Current design equation of horizontal flow SSF-CW system is mostly plug flow
exponential decay method, but in this study, it has been concluded that retarded first
order rate constant is the most appropriate design method for horizontal flow SSF-CW
system for COD removal.

yesUser-generated reviews of visitor attractions, on publicly available websites, such as Tripadvisor, are frequently used in tourism research but feature less often in published cultural heritage research. In this paper, we describe a qualitative analysis of the text from user-generated reviews of three peatland heritage landscapes in the United Kingdom – Ilkley Moor, Thorne and Hatfield Moors, and Shapwick Heath – to better understand the role tangible and intangible cultural heritage play in visitor perceptions and narratives of these sites. Our analysis indicates that visitors tend to emphasise natural over cultural heritage of peatland landscapes and hold plural, highly contextual and sometimes dissonant perceptions; there is no single story of peatlands. This presents both challenges and opportunities for building public appreciation of peatland cultural heritage. User-generated reviews offer, as-yet under-explored, potential data for use by heritage researchers and managers who seek to explore how visitors understand and use sites, and may also contribute to the emerging intangible heritage of heritage landscapes.

Este trabalho trata da elaboração e encaminhamento de uma proposta de reestruturação do sistema de tratamento de esgoto da comunidade do Marujá PEIC SP. A comunidade caracteriza-se pela tradicional cultura caiçara, atividades de pesca artesanal e ecoturismo como fonte de renda, entre outros aspectos. A iniciativa do trabalho partiu da solicitação pelos próprios moradores, por meio da Associação de Moradores do Marujá (AMOMAR), e pela direção do parque, da realização de estudos que viabilizassem a solução de problemas advindos das estações de tratamento de esgoto existentes na comunidade. Sendo um assunto multidisciplinar, o trabalho envolveu etapas com diferentes enfoques para atingir seu objetivo. Foi realizado um diagnóstico para identificação dos problemas existentes nas pequenas estações de tratamento através de análises laboratoriais, entrevistas com moradores e levantamento do histórico de implantação destes sistemas. A partir disso foram pesquisadas alternativas de tratamento de esgoto condizentes com a realidade local com base em parâmetros para projeto previamente estabelecidos. Chegou-se a conclusão de que sistemas combinados de alagados construídos compõem a alternativa mais indicada para o local. Foi feito um breve estudo de caso sobre a utilização desta técnica na Comunidade de Serviços Emaús-Ubatuba/SP, que apresenta características semelhantes a comunidade do Marujá. Durante todo o trabalho foram feitas discussões com moradores locais do Marujá e membros de instituições governamentais e não governamentais a fim de consolidar o envolvimento de diferentes grupos na resolução do problema. Finalmente, foi elaborado um projeto, com fins de encaminhamento para uma instituição financiadora, prevendo atividades de implantação de um novo sistema de tratamento e de envolvimento comunitário em todas as etapas do projeto, visando sua auto-sustentabilidadeThis essay is about the elaboration of a proposal for restructuring the sewage system treatment in the comunity of Marujá, State Park Ilha do Cardoso (PEIC) - São Paulo. The comunity is known by its traditional caiçara culture, fishing handmade and ecoturism as income and they are part of an association of local residents (AMOMAR). The initiative of the proposal was from the local residents together with the direction of the park in order to study the possibilities of adopting solutions for the problems originated in sewage treatment stations which already existed in the comunity. As it is part of a multidisciplinary topic, the work deals with different focuses and phases to reach its objective. A diagnosis was made to identify the problems in the small treatment stations through laboratorial analyses, interviews with the comunity and a historical research on the implement of those systems. Then, a search for alternative sewage tretment was done, adequate to the local reality of the population, stabilishing parameters for the project. It was concluded that the combined system of constructed wetlands are the most adequate alternative for the area. So, a brief study was made about the technique implemented on the Service Comunity Emaús/Ubatuba/SP. During the project, discussions were carried on with the local residents and members of governamental institutions and ONGs, looking for a better participation of different groups in the solution of the problems. Finally, a project was elaborated to be sent to a financial institution, foreseeing activities to implement a new system of treatment with the involvement of the comunity in all the phases

Testo completoAbstract (sommario):
The complexity of interactions that inform policy-making poses several challenges to evaluating the impact of policy research. Two key obstacles to policy-oriented research impact assessment (PORIA) are determining the degree of influence that can be claimed by a knowledge-generating entity and quantifying the impact of a policy-oriented research program. This thesis builds upon prior PORIA efforts to develop a framework for the evaluation of the impact of the Sustainable Wetlands Adaptation and Mitigation Program (SWAMP), an environmentally-focused, policy-oriented research project led by the Center for International Forestry Research (CIFOR). We examine a case study of the Indonesian Forest Moratorium policy to determine the policy's impact on emissions from peat deforestation. Results indicate that the policy has been largely ineffective in decreasing deforestation to date and has in fact been associated with increased deforestation above business-as-usual trends. Nevertheless, our analysis shows that if the moratorium were to achieve full protection, Indonesia could avoid the release of 10 - 20 million tons of carbon dioxide over the next 15 years, which corresponds to a mean social value of $402 - 805 million using a $40/ton social cost of carbon. With SWAMP's timely knowledge generation on tropical wetland carbon dynamics we estimate that $4.03 - 40.26 million of these social benefits can be attributed to CIFOR. Furthermore, through its involvement in the IPCC Wetlands Supplement and the Blue Carbon Initiative, SWAMP stands to positively influence outcomes of the 45 billion tons of carbon stored in non-Indonesian tropical peatlands and the global extent of mangroves, further increasing the impact of CIFOR.Master of Science

The CO2 flux of two peatlands in northern Alberta was examind during the 2004 growing season using eddy covariance measurements of net ecosystem exchange (NEE), chamber measurements of total ecosystem respiration, and empirical models driven by meteorological inputs. The two ecosystems, a poor fen and an extreme-rich fen, differed significantly in plant species composition, leaf area index, aboveground biomass and surface water chemistry. The mean diurnal pattern of NEE at the peak of the season was similar between the sites, however, the extreme-rich fen had a higher photosynthetic and respiratory capacity than the poor fen. Over the 6 month study, the poor fen was shown to accumulate between 2 to 3 times more carbon than the extreme-rich fen despite having a lower photosynthetic capacity. The evergreen nature of the poor fen site allowed for a longer season of net CO2 uptake than the deciduous species that dominated the extreme-rich fen.xii, 126 leaves : ill. (some col.) ; 29 cm.

Outplanting field trials were conducted to identify native wetland plant species that would be useful to coastal wetland restoration on Oʻahu. The effects of soil salinity and soil temperature, initial planting density, and removal of competition on survival and growth of outplanted species were examined. Germination response of four native wetland sedges to different water, salinity and temperature regimes was also investigated. Final survival exceeded 70 percent in four of the seven outplanted species. Soil salinity and soil temperature were negatively correlated with survival in only one species. Planting density and removal of competition had little effect on final survival and growth of outplanted species. Germination under experimental conditions exceeded 25 percent in only two of the four sedge species studied. Overall, seeds germinated to a higher percentage under lower temperatures and salinities than under higher temperatures and salinity levels.

Testo completoAbstract (sommario):
Invasive plant species can alter natural communities and degrade ecosystem function, yet the factors influencing species invasion are poorly understood. Understanding how environmental factors affect plant invasion on compensatory wetland mitigation sites would allow wetland managers to approach invasive species management using a proactive approach (prior to invasion), thus minimizing the likelihood of invasive plants colonizing the system and degrading ecosystem function. In Chapter 1, I introduce the concepts and relevant literature used repeatedly in my project. In Chapter 2, I examine which key environmental factors are associated with altered plant community structure and invasive species prevalence on compensatory wetland mitigation sites. In Chapter 3, I look further into the plant community assemblage at each of my study sites and examine differences in the plant community at varying levels of invasive plant prevalence. For this study, Arthraxon hispidus (small carpet grass), Microstegium vimineum (Japanese stilt grass), and Typha spp. (cattail) were selected as representative invasive plants due to their abundance on non-tidal wetland mitigation sites, as well as their relative differences in ecological tolerance for environmental conditions (e.g., light availability or flooding). Within populations of these species, transects consisting of five 4m2 plots were established on 34 wetland mitigation sites within the Coastal Plain and Piedmont physiographic provinces in Virginia. Along transects, plots were randomly assigned to locations that captured the gradient from completely invaded (invasive species dominant) to uninvaded (invasive species absent or nearly so). For each plot, vegetation abundance data, soil samples, and canopy imagery were obtained for analysis. In Chapter 2, Canonical Correspondence Analysis (CCA) reveals iron, phosphorus, calcium, carbon:nitrogen ratio, canopy cover, and hydrology as correlates with variation in plant community composition across the invasion gradient. In Chapter 3, Spearman rank correlation results show no significant relationship between native species richness and invasive species abundance for any of the three species examined. Further analysis using Sørensen indices of similarity and species accumulation curves corroborate this result. Further study is required to determine causality in the relationships between invasive species and environmental variables, but results demonstrate the need for function-based criteria regarding invasive species management on compensatory wetland mitigation sites. Current standards encourage the use of non-specific herbicides, which may increase the risk of damaging native plant communities and perpetuating the cycle of disturbance and re-invasion on wetland mitigation sites.

Testo completoAbstract (sommario):
In New Zealand, there are many published guidelines about the management of riparian areas. The question needs to be asked, are these guides useful? This research thesis investigates the extent to which riparian management guides meet the needs of the users. This research also considers the importance of riparian management (with regards to the appropriateness of educational guides) in assisting practitioners and the interested public in the management of riparian areas. The main way of investigating this topic was with the help of discussion groups. Discussion groups were held with interested organisations. These groups fell into three categories; Urban groups, Rural groups and Interest groups. The groups were asked to define what would make a guide most useful and desirable to them under three major categories: 1) what the guide looked like, 2) what information was contained, and 3) how was the information accessed. An opportunity was also provided for any further comments. This information was used to create a list of the most popular criteria that existing guides and further publications could be examined against. Eleven criteria were identified as follows: Information should be available online; Have pictures; Include diagrams; Is simple and easy to understand; Contains how to and appropriate methods; Has a plant list; Considers maintenance issues; Identifies where to locate further information; How to contact experts; Is available in libraries; Is in booklet form. The availability of existing information was investigated and its suitability assessed against the criteria. A list of all regional, territorial and unitary councils as well as 'other organisations' that were regarded as sources of environmental knowledge were investigated to see how many had produced information on riparian and wetland management issues. In terms of sources of information, 'other organisations' produce the greatest rate of riparian management information, followed by regional/unitary authorities. Two guides from Canterbury best meet the criteria identified by the interested parties, for the Canterbury region. Each scored 10/11 and failed on different criteria. This led to the conclusion that riparian management guides in Canterbury, while obviously still having room for improvement, are very close to meeting what interested parties feel is most important. Finally, a prototype (model) based on the research is provided for anyone who might be considering preparing a riparian management guide.

The purpose of this study was to utilize structural modeling approach to explore the relationships among recreation settings, visitors’ recreation experiences, satisfaction, and behavioral intention of Kaohsiung wetlands. The visitors of two recreation areas in Kaohsiung wetlands were selected as subjects. The survey questionnaire was constructed according to a structural cause-effect model. The recreation settings and recreation experiences were set as the antecedents; visitor satisfaction was the mediated variable, and the behavior intentions were the effect variable. The findings indicate that the structural cause-effect model is significant; four factors of recreation experience have significant and positive effects on visitors’ satisfaction. The ranking order of positive effects factor on visitors’ satisfaction by comparison with their efficiency values is: the physical environment, service attitude, learning and achievement, and pleasure and relax. Besides, this study also found that the visitors’ satisfaction has significant and high positive effects on visitors’ revisit intentions. The concrete and strategic suggestions and references are offered to related administration agencies according to the research outcome.

The water treatment type constructed wetlands (WT-CWs) are the artificial wetland system mainly constructed for wastewater treatment. Its design principle is to construct a wetland that mimics the function of natural wetlands by ecological methods. The management and restoration of the existing CWs are based on the experience. The quantitative evaluation of health conditions for WT-CWs, however, have not yet been fully established. The comprehensive indicators simultaneously considering the hydraulic efficiency and ecological richness to describe the health levels of WT-CWs have not developed yet. In this study we conducted the Index of Wetland Condition (IWC), which is commonly used to assess the health condition of natural wetlands, to evaluate the conditions of WT-CWs and improve the effectiveness of the management. The study region was Lujau Creek Constructed Wetland in New Taipei City, where the wetland condition was claimed necessary for restoring. We conducted SRH-2D to simulate the water area and water depth and analyzed the hydraulic retention time of it. Comparison between the original and the current conditions of the hydraulic retention time of each treatment unit it demonstrated that the treatment function of this wetland is degraded. Moreover, the IWC with 27 sub-indicators was evaluated with data measured from 2014 to 2016. The results show that the IWC does not reflect the health status of the Lujau Creek Constructed Wetland. The sensitivity analysis of IWC was also conducted. According to these results, bird diversity and bird abundance were not the most sensitive indicators, even though they should be important indicator in wetland conditions. This study tried to modify the IWC soring system with the method to change the weight and lengend range. The modified IWC (MIWC) showed that it can correctly reflect the health status of the Lujau Creek Constructed Wetland. The sensitivity analysis of MIWC, on the other hand, showed that the indication of the bird diversity was improved. MIWC again was applied to the Shuimokeng Stream Constructed Wetland in the Guandu Nature Park, where the wetland condition is stable. It porved that MIWC can also reflect Shuimokeng Stream Constructed Wetland with the health status. This study shows that the consideration of IWC are general and versatile; and suitable to be modified for Water Treatment Type Constructed Wetlands as the specific index. With this proposed MIWC as the indicator, the wetland can be quantitatively managed. Moreover, based on the case studys we showed that MIWC could increase the sensitivity of waterfront vegetation diversity sub-indicators and bird diversity sub-indicators.

The purpose of this research document was to determine a relevant, responsible and appropriate architecture for the design of an Environmental Research Facility for the iSimangaliso Wetland Park World Heritage Site in Northern KwaZulu Natal, South Africa. The nature of this architecture was generated through the investigation of current literature, case and precedent studies and personally conducted interviews with a number of informed professionals. The reason for these recommendations was ultimately the design of the facility for research and education, the goal was always the eventual application of the findings into a design. Ultimately, an appropriate architecture for an Environmental Research Facility for iSimangaliso Wetland Park, a UNESCO World Heritage Site, is one which is accountable and responsible regarding the social, economic and environmental aspects of its design. These three rubrics of sustainability were then unpacked and investigated in order to clarify how this would be most effectively be achieved in the eventual design.Thesis (M.Arch)-University of KwaZulu-Natal, Durban, 2008.

"Testing aquatic macroinvertebrate and plant techniques for the biological assessment of wetlands : a consideration of the effects of errors and implications for sampling design". 2006. http://handle.uws.edu.au:8081/1959.7/18015.
Testo completoAbstract (sommario):
Rapid bioassessment techniques used for aquatic macroinvertebrate and plants in wetlands were tested in New South Wales, Australia. Wetlands surveyed ranged from coastal wetlands in the North and Central parts of the State, to tableland wetlands west of Sydney. Wetlands varied in dominant vegetation, hydrology, substrate and level of human impairment. Different options for sampling (mesh size, live-picking times, quadrat size, number of samples or quadrats) and analysis (taxonomic resolution, transformations, biotic indices, multivariate and univariate analyses) are compared to determine optimal sampling effort and evaluate the effects of errors or variability. Results show that, for wetlands of New South Wales, sampling procedures developed and tested in streams and other regions of Australia may not be the most efficient. Using the data from 21 wetlands in New South Wales, a number of analytical techniques were evaluated for the effects of errors. Results show that species-level multivariate analysis is more sensitive in detecting less obvious differences between wetlands (i.e., small effect sizes), while family-level analyses are more appropriate for large effect sizes. A modified waterplant index was developed that is simpler and has a wider application than the other Australian options available. Inherent problems in each index tested were addressed. The results show that the process of summarising a large amount of information into a single value will result in the loss of both information and variability between samples and this cumulative effect of error may effect the assessment of wetland condition. The practical outcome of this thesis is a set of standardised steps to assess wetland quality using biological assemblages. The results show that protocols and indices for rivers are not directly transferable to palustrine, vegetation dominated wetlands. I present protocols that are more appropriate to wetlands and recognise that each protocol would need to be adapted for each wetland type. Despite the need for flexible protocols, I promote the need for a standard approach to wetland sampling and the need for consideration of the effects of errors in sampling designs. This study highlights the need for more research on the response of specific stressors to wetlands flora and fauna. The results from this study also show that wetland macroinvertebrates and plant communities can be used as surrogates in multivariate analyses for detecting large differences between wetlands (wetland types) but that impact assessment requires more detailed investigations including species identification and careful consideration of the choice of reference and control sites. In conclusion I emphasise the need for scientific rigour in the use of biological indicators and consideration of the effects of errors and implications to sampling designs.Doctor of Philosophy (PhD)

This study uses Chinglou and Caiyuan Wetlands of Penghu County as the research plot to establish the fauna basic information of decapod crustacean. The results show that, in terms of Decapoda fauna, there are 67 species in 20 families of Chinglou Wetland; include 13 species in 3 families of Macrura, 11 species in 4 families of Anomura, and 43 species in 13 families of Brachyura. Among these, Ocypodidae of Brachyura has the largest proportion with 12 species, while Amphidromous has 6 species in 4 families. In Caiyuan Wetland there are 49 species in 16 families; include 11 species in 3 families of Macrura, 6 species in 4 families of Anomura, and 32 species in 9 families of Brachyura. Among these, Portunidae of Brachyura has the largest proportion with 10 species, while Amphidromous has 6 species in 3 families. The two wetlands have a total of 22 families with 80 species for decapod crustacean, and 6 families with 9 species for amphidromous. In terms of distribution, Chinglou Wetland has the most species in coral fragments habitat type with 34 species in 10 families, and while Caiyuan Wetland has the most species in mangrove habitat type with 13 families and 31 species. For the distribution of indicator species, Chinglou Wetland has two species of Cardisoma carnifex in Gecarcinidae and Uca splendid in Ocypadidae, they are mainly distributed in the mangrove restoration area; Caiyuan Wetland has Helice formosensis in Grapsidae which is mainly distributed in the mangrove planting areas within fish ponds. This research also finds that both Chinglou and Caiyuan Wetlands have many coastal projects that can impact the habitat and the ecological path between the land and sea ecosystems. Therefore, this report also provides recommendation in hopes of making the wetland of Penghu and the related ecosystem further improved.

This study mainly hopes that through the "environmental art", the crystallization project of art and science, it is possible to explore whether it is really influential for the fishing villages with partial resources and seemingly insufficient resources. And its impact on the community's cohesion, emotion, economic, environmental awareness, art, tourism and other directions, whether there are any specific changes. This study intends to adopt literature review methods, field surveys, qualitative in-depth interviews, etc., and the research objectives achieved are: First, discover the characteristics that must be possessed by environmental art. Second, through the promotion of environmental art, explore how people, communities and the environment have changed. In the end, the environmental and natural materials of local materials are combined, and the international experience in the field of vision is combined with the characteristics of environmental art such as educational significance. Environmental art has also changed the emotional connection between ChengLong villagers, the attitude towards environmental attitudes, and the ability of residents to create their own creations; art is the way, and environment and community are the goals, through the ChengLong Wetlands International Environmental Art Project, The power to unite the community has also led to ecological education.

The wetland is the most important eco-system on earth but it was rapidly disappeared because of economic development and people unknown its value. The artificial wetland is designed to improve the water environment, but there are many functions such as ecological conservation, the scenic establishment, environmental education and leisure. This study is aimed at finding the evaluative indicators of ecotourism development of the artificial wetlands. The Fuzzy Delphi method was used to find out the evaluative indicators and its weight. Through the questionnaire of 17 experts and scholars in three times, there are five parts in the evaluated framework include the eco-resources, eco-environment, management, location and the travel development and within the total of 22 indicators. Furthermore, the indicators were applying to evaluate the constructed wetlands in Da-peng Bay and found it has the grade of “good level” to be the ecotourism site (the evaluate score is 66.8). The travel development got the highest score among the five parts, which means the artificial wetlands in Da-peng Bay are suited to develop ecotourism. But the management got the lowest score, because there are not travel activities held in the artificial wetlands of Da-Peng Bay now and the interpretation and environmental education are under planning. As the result of research, the study case will strengthen the following work to develop ecotourism in the future: (1) Eco-environment and eco-resource: to strengthen the diversity of habitat, species of resource and the feature of each wetland. (2) Management: Establish the educational center of environment and design environmental educational courses for different eco-travelers. (3) Location: to strengthen the bikeway facilities between the wetlands, such as shelter, route. (4) Travel development: cooperate with the local community and train the resident to monitor the environment and manage the artificial wetlands, also to provide the work opportunities and increase benefit for the local communities.

All of these characteristics attract a number of tourists from Taiwan and abroad to visit Kinmen. In order to develop tourism industry in the market of Kinmen, the authors conducted the study. The objective of the study was to explore service marketing through empirical research into the in-depth context of tourism including tourist satisfaction, management and operation, on-site illustration service, and tourist experience. Further, the study aimed at enhancing service quality of exhibition halls as well as increasing tourist revisiting willingness. To carry out this research, a self-administered questionnaire survey was conducted between February and April in 2009. There were 468 effective questionnaires, representing a rate of 78%. The results of the study were as follows: (1) On-site illustration service affects tourist satisfaction. (2) Whilst after-visit experiences of the tourists were divided into four factors of characteristics－content and quality of service facilities, security of recreational facilities, convenience of public facilities, and characteristic of local ecology, the results indicated that all of the factors have positive significant relationship with tourist overall satisfaction. More specifically, “characteristic of local ecology” affects the degree of tourist satisfaction the most. (3) The quality of environment facilities affects tourist satisfaction physically and visually. (4) Tourist overall satisfaction has positive correlation with tourist willingness of revisiting and recommendation. In other words, the more tourist satisfaction with Kinmen, the more tourist willingness of recommendation to visit Kinmen. Keywords: services satisfaction, tourist experience, willingness of revisiting

Abstract At Tou-chian River of Hsin-chu county, the area of 1st and 2nd stages of constructed wetland is 1.9 hectare. It includes 16 different pounds from A to P. During the period of research, Sep. of 2007 to Aug. of 2008, the plants spatial heterogeneity had reach the highest percentage of 39% in Jan.2008, and the lowest of 22% in Aug. 2008. The percentage under maintenance control was between 20 to 40%. Plant species proportion in maintenance plots appears a well mix status, the species in the vegetation succession environment plots are mainly Bidens pilosa L.radiata（B1.）Sherff. The species in maintenance plots are much more divers than the vegetation succession environment plots. Plant species proportion in vegetation succession environment plots was gradually becoming even, the proportion of plant species was in an average status. From the observation of the plants’ formation of the wetlands surrounding, suppose in the undisturbed natural succession, it will eventually become a low altitude river basin vegetation structure of Taiwan. Melia azedarach L. and Trema orientalis (L.) Bl. will become the main members of this plants composition. There are 20 family and 166 species of water plants recorded in the survey of Aug. 2008. It has 4 fmaily and 7 species more than the record of Dec. 2004 when the construction was finished. Nuphar shimadai Hayata, Bacopa monnieri（L.）Wettst. and Polygonum orientale L., these three species did not have record during the survey period. During the research period, the on land plants appeared the most in spring, total 61 family and 166 species. The least in the winter, 57 family and 149 species were recorded. However, there are 26 family, 50 genus, and 64 species more than the survey record of wetland planning in May 2004. Among the wetlands region, there are average 63% of native species in all seasons. Creating more chances for the native plants to survive by maintenance, the native plants increase 36 species in compare to the record of 2004. Ammonia Nitrogen removed treatment was 71% in Aug.2008, had not reached the design standard. Excluding this month, all other months had exceeded the standard. It even reach 98% percent in Sept. 2007. The annual treatment average had reached 86%. However, the suspended solid (SS) treatment is not very effective, it might be caused by the lack of plants in the pond, therefore did not meet the design standard. BOD5 and NH3-N concentration in monthly average had reached the designed standard. Suspended solid (SS) concentration did not meet the standard in Sept., Oct. of 2007 and Apr., Mar., Jun. of 2008. The monthly average of water quality out concentration is above the expectation of design standard. After the relative analysis of the plants spatial heterogeneity and NH3-N removed treatment in every pond, the reliability analysis result of the Cronbach’s α coefficient is 0.83. In pond A,H and J, the analysis result shows the changing of plant spatial coverage is highly related to the NH3-N removed treatment, and pond A had the most remarkable result. From the results of analyzing the plant diversity, pond A also had the most different and divers plants in all seasons. Therefore, we conjectured that the diversity of plants might also be close related to the NH3-N removed treatment. The P value in pond D is 0.096. However, it does not mean that the greater area of plant spatial heterogeneity is the better of NH3-N removed treatment would be.

Taiwan passed its Wetland Conservation Act in 2013. It is a great improvement on conserving and wisely using wetland resources in Taiwan. This new Act adopted the mechanisms of wise use, avoiding, compensation mitigation and offset to prevent, minimize and mitigate the adverse impacts causing by developing of the wetland resources. Taiwan is an island country and rugged mountain occupied long strip from North to South, which limits the space and development of wetlands. Therefore, the utilization of wetland resources shall be careful and follow the wise use concept properly to avoid, minimize and compensate the mitigation of wetlands. Under the pressure of rapid economic development, the first mission of the legislators is taking the measures of wetland compensatory mitigation to replace the lost aquatic resource function and acreage. Although Taiwan is not member of the Ramsar Convention, it is one of the most imperative spots for the migrate species. His determination and efforts to protect the wetland ecosystem could not be ignored. In the new Wetland Conservation Act, the legislators adopted the wetland mitigation sequence from the U.S Clean Water Act but failed to formulate the implementation on compensatory mitigation comprehensively. Once we admitted the wetland compensatory mitigation measures could contribute to the protection of wetland ecosystem. The recognition on the types and size of wetlands in Taiwan are totally different from the U.S. is important. Therefore, this article introduces the dilemma and provides applicable suggestions on suitable and feasible rules on wetland compensatory mitigation, inter alia, mitigation banking into the future modification on Wetland Act. How to mitigate the adverse impacts is worth to encourage in our own wetland management policy. This article will also provide effective and feasible recommendations to our government for conserving and sustainable developing the precious wetland resources in Taiwan.

Constructed wetland has the function of purifying the wetlands and ecological protection. After natural disasters and man-made damage situation, those successful cases are encouraging while the failures of the cases are questionable. The topic whether a wetland should based on purifying the water quality and be ecological preservation-oriented or should based on ecological preservation with purifying the water quality as oriented is still debatable. In addition, we should fully consider how to become compatible with the local environment. Although the study of constructed wetlands starts late in Taiwan, so far we still lack of document that aims on the research of assessment factor after the completion of constructed wetlands and assessment methods. The method of this study is divided into three main stages. The first stage is to use the Modified Delphi Method questionnaire to come up with the important assessment factors in constructed wetlands. The second stage is to use the Analytic Hierarchy Process (AHP) questionnaire to obtain a reasonable ratio about the assessment factors, and use it as the basis of statistical analysis in the next stage. The use of this questionnaire is to quantify the assessment factors and analyze the percentage of each factor. Finally, we use the Grey decision-making analysis on the third stage to assess the best site to exemplify and become a basic reference for the future plan of the constructed wetlands considered water reclamation.

This thesis is to study Taiwan wetland planning and design which is to explore how a proposed detention wetland system work to solve flooded Southern Taiwan Dapeng Bay. A wetland system is composed of a variety of disciplines such as geography, hydrology and landscape architecture and ecology. It also includes engineering, civil engineering, social education and environmental protection. Due to rapid climate changes, this thesis is to study the design and planning based on the assumption of increased frequency of storm water instantly, and on the upgrade or more duration and detention. This study is to study based on soil and water conservation technical specifications. That is, dimensionless formula to calculate the amount of water set within the design area of each return period, and is 24 hours storm water detention facilities. The study area of this thesis is about 155 hectares. According to the relevant regulations and codes, this study laid down provisions for a 10-year recurrence period. A 10-year recurrence or storm return period is based on the studies of soil and water conservation technical specifications by Taiwan Government regulations of dimensionless- equation. The total amount of water is to obtain a 24 hour- of 10,117,000 cubic meters, which requires a detention depth of about 6.5 meters. Another estimate of a 50-year return period, 24 hours of total amount of runoff and storm water is about 12,658,000 cubic meters. The said detention depth is estimated about a 8.2 meter-depth for design and planning. A 50-year return period for the design of detention capacity is thus the designed runoff and storm water volume for this thesis. In the end, this study is to design a detention pond with a depth of 8.2 meters according to the studied data. The original terrain elevation is about 1.8 meters high, so depending on the depth of 50-year return period of detention from approximately -8 meters. Reproduce the detention period can meet the functional distance in 50 years. In this paper, so the design of detention amount to the total initial configuration and detail design, was a case study. And so may recommend further research and in the future.

A wetland, land-based area often merged by flood or tide, offers the most diversified ecological environment. It is also one of the alternatives for water quality improvement considering locality. The artificial wetland has been not been widely implemented because it is still yes undergoing further development. The outcome of ecological rehabilitation using wetland is disputable as water quality control indicators are not well-defined. The success of wetland in water pollution control requires vigorous investigation on several key factors. The Grey Relation is often used to describe a dynamic, quantitative measure identifying the trends and discrepancies among decisive issues. It is crucial for decision makers in system control understanding the details and reliability of information resulting from the wetland. This research is based on a case study conducted at the Tao-Chian Creek Ecological Park located in the Chu-Dong municipality in Hsin Chu County The information such as：Suspended Solid (SS), Biological Oxygen Demand (BOD),ammonia nitrogen content, local climate, water temperature, sunlight exposure, and nitrate nitrogen content are collected and analyzed for a certain period of time. There are the few environmental aspects taken into account in the study. The relationships between the water quality improvements with respect to each factor are characterized using the Grey Relations. It is hopeful to be implemented as the base for constructing artificial wetland rehabilitation in water purification in the future.

Taiwan is a beautiful island with rich and diversified species and varied landscape scenery. However previous main consideration of economical development has resulted damage of resources, and large scale land development also has decreased, split, and fragmented important ecological habitats. In order to ensure Taiwan’s environmental resources, this research uses Guandu Nature Park as an example, and uses Habitat Evaluation Procedure to study the relationship between bird habitat and environmental factors enabling to fulfill wetland development in three principles preservation, restoration and education. This research uses existing data to establish biological suitability index for water quality factors - such as salinity, PH, dissolved oxygen and conductivity, as well as general habitat suitability index. It also analyzes and investigates species, richness and indicator species. The research results show the more sample quantities, the more representative on habitat models. Then it uses diversity analysis additionally to establish habitat model, and discovers certain correlation in between. Previous ecological investigation only analyzed biological indicators richness index, diversity index and equitability index; without further analyzing correlation between these indexes and environmental factors. Therefore, this research can be a good reference to other biological habitat environmental evaluation and environment management in some other area. We also suggest engineer participate in this kind of research in future to have further investigation on correlation between species and habitats.

Taiwan's coastline is narrow and the mountains fall away steeply and the torrential flow from the steep slopes often forms alluvial plain at estuary mouth such as Zhuan wetland of Toucheng Township in Yilan County. Zhuan wetland creates some coastal wetlands that nurture enormous biodiversity including Egretta eulophotes. Zhuan wetland has been categorized as local-level important wetland since the Wetland Conservation Act begins the implementation of the Act on 2nd February 2015. Several key causes of wetland protection project termination in 2016 including the unfair expropriation compensation process with the announced land values that land owners repudiates, the restricted land use that with low land value, as well as the insufficient funds from the Yilan county government. To solve the situations that superior natural resources cannot be effectively protected, and ecological conservation work has not promoted, this study aims at restarting the wetland preservation plan and proposes an effective method to establish the business model of the wetland conservation company. Hoping to solve the economic problems that many wetlands is facing, achieving the purposes of autonomous sustainable operation in ecological reservations, landscape maintenance, and economy. The study integrates the benefits of power economy such as energy and wind energy with the promotion of agriculture and fishery technology, taking roots in conservation education. Eventually, to fully manage the wetland effectively with economic benefits.

ABSTRACT The study on implementing the ecological art creation of “Wetlands: a perfect place for a date” aims to understand the interaction between the natural environment and the related development of art. Since the 1960s, according to the literature, the importance of preserving the ecological environment, among the many environmental issues, has been deeply accepted by all social levels from each corner. Artists who interact closely with the environment have created many works related to ecological issues. After the 1970s, artists keenly concerned about the environment have used various art forms to express their love and passion for the land. Due to the influence of western trends concerning art and the environmental transition, many artists who possess a profound environmental appreciation, have produced works full of love and care in the 1980s related to this issue. It is hoped that effective recognition and active implementation can be carried out in relation to caring for the environment and that the process and value of art catering to this issue can also be better understood by analyzing literature on experiencing ecological art exhibitions. Chapter I is the introduction; Chapter II offers literature analysis and discussion on ecological art development and evolution; Chapter III is the case study of “Wetlands: a perfect place for a date”, in terms of ecological art planning; Chapter IV is the implementation status; and Chapter V provides the conclusion and proposals. The conclusions resulting from an analysis of the relevant literature are as follows: (1) There is a close relation between ecological art development and the natural environment (2) The roles that artwork plays in relation to the natural environment continue to evolve; for instance, the themes include: nature worship, creative elements, environmental transition, topical subjects and environmental issues, etc. (3) Many Taiwanese artists have focused on environmental issues and their art forms try to awaken a concern and passion for the land. (4) The development of interdisciplinary art in Taiwan is flourishing. The conclusions resulting from the “Wetlands: a perfect place for a date”: (1) The purposes and performances in interdisciplinary art design can be achieved following integration. (2) Due to current ecological issues, environmental protection is the underlying concern in many constructions and design projects. No technology that damages the environment is used. (3) Ecological art is referred to in each part of the construction. No consideration is made solely in regard to art, but for the overall environmental health and beauty. All forms of pollution are rigorously avoided. (4) The goal of ecological art creation is mainly to enhance the public’s introspection, to elicit their attention and concern by examining art planning and implementation. The study aims to evoke a concern for the ecological issues by displaying art creation on the wetlands. While setting up the driftwood by crane, the researcher noticed the importance of the art in harmony with the environment. Introspection on how artificial design and nature can be well integrated is of greater critical importance than art creation alone, or aspects of traditional appraisal.

This study has employed the theory of planned behavior (TPB) to establish a model of environmental behavior of ecotourists in Chouchai Wetland Park. The variables of the model include Environmental Concern (EC), Normative Beliefs (NB), Behavioral Beliefs (BB), Control Beliefs (CB), Subjective Norm (SN), Attitude (AT), Perceived Behavioral Control (PBC), Behavioral Intention (BI), and Behavior (B). Structural Equation Modeling (SEM) would be applied to validate the environmental behavior model of ecotourists. The data collected from the closed questionnaire. Total of 370 questionnaires were collected and used SPSS l3.0 for Windows and AMOS 5.0 for Windows as analysis instruments. The results were summarized as follows: =332.160, P-value<0.01, the P-value was significant. It was resulted in too many samples. So adopting other fit index, the proposed model is well fit the environmental behavior model of eco-tourists (NFI＝0.894, NNFI=0.929, CFI=0.941, RMSEA=0.055, PNFI=0.744, /df=2.102). After checking for the effects of the situation-specific TPB constructs, environmental concern has significant direct effects on the attitude, normative beliefs, behavioral beliefs, and control beliefs; attitude and behavioral control have significant direct on behavioral intention as the subjective norm has no significant. Behavioral intention has significant direct effect on behavior itself. Furthermore, behavioral intention of the high NEP score subgroup can be 63 % explained by subjective norm, attitude and perceived behavioral control whereas behavioral intention of the low NEP score subgroup can be 73 % explained. The behavioral intention of the high NEP score subgroup is mainly determined by attitude, and perceived behavioral control is the second influence. And then the behavioral intention of the low NEP score subgroup is mainly determined by attitude. In both subgroups, behavioral intention has strongly significant direct on actual behavior. However subjective norm has no significant direct on behavioral intention.

A wetland was constructed on the Puzi river flood plains in this research. Several aquatic plants were grown on this wetland. By the interaction among plants, soil, and microorganisms, which is the natural autonomous purification measure, a certain section of Puzi River in Chiayi County was purified to improve the water quality and the utility. The sewage treatment by using constructed wetlands has been widely used in both international and domestic area and has concrete effects. It，s advantage is low capital investment cost, easy to operation and maintenance, low utility requirement and energy conservation, enhancement of the natural landscape, and the rechargement of underground water…etc. This research was conducted on the flood plain near Puzi River. The total measure of area about 4.41 ha. Where Ipomoea aquatica, Pistia stratiotes L., and Eichhornia crassipes(Mart.) Solms…etc were planted. There are take the water from Puzi River to this constructed wetlands. The flow rate was about 3,000 CMD. The purpose of this research was to compare the capability among two-stage （FWS and SSF）constructed wetlands above to purify the water quality of a seriously polluted river, and the water quality of which was improved. The result has shown that two-stage constructed wetlands have obvious effect to purify the water quality of a polluted river. However, the constructed wetlands is easily influenced by climate, especially typhoons. The facility will be totally ruined by typhoon because of no artificial protection. The selection of location, therefore, needs to be considered carefully. The results of this study could be used as a reference for developing constructed wetlands to purify the water quality of a river.
