Study On Coastal Wetland Regional Coordinative Development Of Resource, Environment, Economic And Society

Due to human's unconscionable exploitation and utilization, such as inning, red tide, seawater breed, wantonly draining sewage of industry and living, constructing coastal project, coastal corrosion, resources of coastal wetland in our country are suffering seriously destroy. Therefor, coordinative development of economy, society, resource, and environment of coastal wetland region is studied in this thesis.System analysis, qualitative and quantitative analysis and games theory are used to study coastal wetland regional coordinative development of economy, society, resource, and environment. The main contents are followed:(1) Introduction. Introducing the background of study, presenting framework of the thesis;(2) Theory study. After analyzing related theory including eco-carrying-capacity theory, sustainable development theory and eco-system theory, view of scientific development is put forward, which would guide coastal wetland region's coordinative development of economic, society, resource and environment;(3) System analysis. From system angle, characteristics and intrinsic coordinative mechanism of economic, society, resource and environment are analyzed, DPSIR framework and system dynamics model of coordinative development of coastal wetland region are constructed, and simple approach of improving coastal wetland regional eco-system is also advised;(4) Conflicts analysis. Including the relation of market and government to collocation resource and environment of coastal wetland region, equity among and in generations in collocating resource and environment of coastal wetland region, conflict and cooperate of multi-benefit-part in coastal wetland region, the strategies are presented accordingly;(5) Modeling. In this part, RBF-ANN model for generally estimating eco-carrying capacity of coastal wetland region is presented. What's more, set pair theory is used to gained economic, society development state degree and resource, environment damage state degree. Further, coordinative development degree of economic, society, resource and environment is calculated using improved Logistic curve;(6) Instance. Eco-carrying capacity and coordinative development degree of Yancheng coastal wetland region is assessed. The result indicates that during 1998-2002 five years, eco-carrying capacity stays middle-level, while coordinative development degree stays weakly coordinative stage, which all accord with the real situation of Yancheng;(7) Policy analysis. Policy is discussed which coastal wetland region should adopt for regional coordinative development.(8) Conclusion and prospect. In this part, the conclusion and innovation are concluded. However, there is insufficiency in this thesis, which would be solved in future study, so the prospect is put forward in the end of the thesis.
