Research On The Change Of Industrial Structure Of Chaohu Basin And Its Eco-environmental Effect

Mutual influence and evaluation mechanism of human activities and ecological environment, is the ecology, geography and environmental science disciplines common research focus in the current. When the micro-effects of environmental pollution control been constrained, people turned glance turned to adjust the industrial structure. But the industrial structure as a link between human activities and the ecological environment is an important link, there is significant interaction between its type, the ratio of each other, regional resources and the environment, consumption of resources and the effect on the ecological environment is decided by the different types of industrial structure. Therefore, for the industrial structure and the regional environmental impact assessment, analyze and recommend sustainable development to guide lake-basin has some theoretical and practical value.This paper take the Chaohu lake basin one area of《Water Pollution Control in Key River Valleys "Eleventh Five-Year Plan"》, established by the state environmental protection administration for example, analysis environmental effects of industrial evolution of river basin, construct different industry types of ecological environment influence coefficient, make a quantitative evaluation on the response of natural ecological of structure evolution of Chaohu lake basin, The results show that the industrial structure of three cities occurred a great change in basin in during the research period, impact Index of eco-environmental of industrial structure changes in volatility, but overall high, pressure on regional ecological environment is greater, watershed municipalities need to further adjust and optimize the industrial structure. The main steps are as follows:first, from the theoretical analyze the mechanism of industrial structure impact on environmental, and then analyzed the evolution of Chaohu Lake basin cities'industrial structure and their environmental conditions; we have analyzed the impact on the environment(atmospheric environment, water environment and solid environment) of industrial structure's three times evolution, the third step, we carry out further empirical analyze subdivision environmental effects of industrial structure evolution, from those we can get the ecological environment's impact index of Chaohu Lake Basin Structure, then comprise its numerical difference at different times and quantitative composite evaluate the environmental effects of regional industrial structure change; The fourth step, based on the empirical analysis, we propose how to adjust and optimize industrial structure and realize harmonious development of resources, environment, economic and social.
