Study On Harnessing The Water Pollution In Chaohu Basin

The essay is based on the situation of the water environment pollution and its protection in the Chaohu basin. We could research some problems in these fields:1 The situation and the historic reason of the water environment pollution in the Chaohu basin. 2.The analysis on the institution of the water environment protection in the Chaohu basin. 3.The analysis on the participants in the water environment protection in the Chaohu basin. 4.The analysis on the technology in the water environment protection in the Chaohu basin. 5. The difficulties and the solutions in the water environment protection in the Chaohu basin when the economic institutions are transforming. 6. One tool:the DSS (Decision support system) for the water environment protection in the Chaohu basin.The research has two objects. One object is to find the institution reason and the institution selection with the method of the neoclassic economics and the new-institution economics,to find how the allocation of the property right exert the influence on the allocation of the water resource,to research the participants" action mechanism,to analyze the elements of the deficiency in exchange of the management technology,to analyze the mechanism of the technology innovation,to analyze the difficulties of the water environment protection and to give some suggestion. Another object is to research the construction of the DSS for the water environment protection with the support of the computer technology,to analyze the whole structure,to find the hardware structure and the software structure,and to find the scheme of building the structure of the WEBGIS.In the first part,we present the feature in the Chaohu basin and analyze the water quality of the Dongpu reservoir and the 9 rivers in the Chaohu basin,toanalyze the historic reason of the water pollution:the surface flow in relation with agriculture,the loss of water and soil,the industry and domestic sewage,the Chaohu Floodgate,the lack of the enough preventive measures.In the second part,we try to analyze the water environment institution with the method of neoclassic economics and new institution economics. We analyze the institutional reason in the problem of the water pollution (The direct reason is the failure of the market method while the indirect reason is the failure of the government method),and we compare each water environment institution (or in other word,the protective method),among which the focus is the Pigou method,one of the economic institutions. So are the definition of property right related to water environment and the exchange of the right of pollution,which can be regarded as one of the Koase methods. We also presume that the water environment quality is not a sort of pure public product but a sort of public product belonged to some regions. With this presumption we analyze the benefit relation in the protection of the water environment and the selection of the water environment institutions. After presenting the history of the water environment institution in the Chaohu basin,we seek the interaction between the institutional transformation and the protection of the water environment.In the third part,we analyze the action mechanism of the participants in the protection of the water environment. Firstly,we research the mixed strategy equilibrium between the governments. Secondly,we research the characteristic of the action played by firms and peasants. Thirdly,we deduce the interact effect:the failure of the government method.In the fourth part,firstly,we discuss the management technology used in the protection of the water environment and the management technology included inthe governments' plan in which the main method is to decrease the water pollutions brought by some sources,such as agriculture loss. P-bearing detergent in the sewage,etc. Then we analyze why the exchange of management technology is deficient. In the end,we analyze the mechanism of the management technology innovation in the protection of water environment.In the fifth part,we analyze t...
