Study On The Ecological Function Regionalization Of Jin Cheng

To coordinate contradiction between the development and ecological protection, safeguard the sustainable development of regional economic, on the basis of analyse the space distribution disciplinarian of the regional ecological environment, divide it into many different part, revealed the characteristics of each region, provide scientific basis for the regional environmental protection and construction, reasonal use of resources and rational distribution of industrial and agricultural production, provide technical means for environmental management departments. This study has a positive and practical significance and a theory guiding significance.The object of this study is the complex ecosystem of Jincheng of Shanxi Province , use the idea of systerm engineering to established the ideological line of technology. According to specific questions, use statistical methods, DEM model processing, interpretation of remote sensing and GIS technology, from analyze the status of the ecological environment, environmental sensitivity and importance of ecosystem services,to comprehensive evaluate the features and problems of the regional ecological environment, make the technical method of research systematism. Form a technical method system of ecological function regionalization. According to the different ecological environment sensitivity and importance of ecosystem services of the different regions, Jincheng will be divided into five stair regions, eight twain regions and 18 third class regions, and give a simple analyse to the ecological construction and environmental management countermeasures.In allusion to the actual situation of Jincheng, in this study,it add evaluation of soil resources, mineral resources assessment and evaluation of solid waste to the evaluation of status quo of the ecological environment. In the evaluation of ecological environment sensitivity,we evaluate the sensitivity of the geological disasters of Jincheng ,this evaluation is different from the geological disasters in coastal cities, it mainly refers to the surface subsidence caused by mining issues. This study presents a new method of evaluation to geological disasters sensitivity, it is different from anyothers in select evaluation factor and classification standards, it is more suited to some inland areas where mining industry is developed such as Jincheng.This study make a more systematic analysis of the ecological environment of the Jincheng, and the results provide a scientific basis for guiding to the regional ecological environmental protection and construction, as well as give a scientific basis for management to the environmental department. In addition, municipal ecological function regionalization has just started, the method is not adequate, this study can provide some theoretical reference to other cities.
