Zoning Ecological Functions Based On Ecological Sensitivity Evaluation

With the speeding up of urbanization in our country, development of urban economy at thesame time, a lot of ecological problems have emerged, such as deterioration of ecologicallandscape, location benefit of the land is greatly reduced and the city pollution is increasinglyserious, seriously affected the people’s health and the construction and development of theeconomy. So, how will based on the nature and ecological efficiency for the natural environmentand regional energy, establish suitable strategy for urban or regional development and ecologicalenvironment protection, bring about the sustainable development for the urban or regional ofeconomic social, it has become an important subject faced by the government and the scientificcommunity in our country.On a basis of Chongyi country as the research target, collection and sorting the basic data,the current situation for the present ecological environment as a starting point, on the analysis forthe ecological problems of Chongyi country at the same time, conduct the ecological environmentsensitivity evaluation for the Chongyi county, on the basis of full analysis and evaluation,Conducted to ecological function division work for Chongyi country, shows the different spatialdistribution rule of ecological environment system for the Chongyi country. Mainly divided intothree steps:(1) Before confirm the index system, through read a large amount of relevantinformation, conduct the collection of basis data, then select five aspects with hydrology, soils,habitat, geological disasters, and farmland coercive conduct ecological environmental sensitivity.(2) Using the ArcGIS software for factor analysis, according to the results of the analysis, usingthe method of spatial superimposed for single factor, obtained the sensitivity of thecomprehensive evaluation index, based on this conduct with ecological function zoning.(3)Described the characteristics of each functional area, showing the ecological status andenvironmental issues of the various functional areas, to give scientific management measures andprotection recommendations for achievement sustainable development of Chongyi country.Finally, on the basis of the above study, According to the reality of Chongyi County,proceed from the relationship of coordination ecological environment and economic construction,offer countermeasures and suggestions To explore reasonable and effective land utilization typefor point of view. Guiding ecological protection and construction planning for regional, guidingthe development and utilization of resources and industrial layout within the regional. Stand outthe position of the ecological environment in the social-economy development, develop strongpoints and avoid weakness to full play regional advantages, to achieve optimal location ofresources. Provide reference for the establishment of ecological compensation mechanism forChongyi country and achievement social-economic-ecological sustainable development of the three.
