Study On The Ecologieal Funetion Regionalization Of Liangzihu Destrict

To coordinate contradiction between the development and ecological Protection and safeguard the sustainable development of regional economic, on the basis of analysis the space distribution disciplinarian of the regional ecological environmental, the paper defines the structure, course and character of space distribution of type of the eco-system in Liangzihu Destrict,and forwards the main eco-enviromental problems, reasons and its space distribution pattern accordingly. At the same time, the paper also analyse the change of ecological footprint and ecological capacity of Liangzihu Destrict from the year of2007to2011and its effect on regional social economic development and environmental protection, moreover the paper proposal of eco-function regionalization, eco-environment of different eco-function areas and its social economics function, direction of development and management measures. Finally, the paper has built up a space and geographic frame for Liangzihu Destrict on general management of construction of eco-city, optimized setup and rationalization of resources and economic development, and protection of eco-environment.The main content includes the following aspects.(1) The object of this study is the complex ecosystem of Liangzihu Destrict, and using the method of system engineering to establish the ideological line of technology. In the meantime the research analysis its natural landscape pattern and difference through the topography, climate, resources, vegetation, population, GDP and other Index terms, in addition, organized the data of Economic development and social development.(2) This thesis uses the revised ecological footprint and ecological capacity model to analysis Liangzihu Destrict’s ecological footprint and ecological capacity of dynamic change trend around five years which is based on a new index system, and also have a quantitative evaluation of the its ecological footprint and ecological capacity of supply and demand development status in those years. (3) Based on GIS technique and SPSS statistical technique, and through the cluster analysis of some elements, Liangzihu Destrict was divided into4function sections, and the future development guide has been advanced. Furthermore, according to eco-function regionalization we divided land space into four function zones, including prohibited development zone, ecosystem restoration area and optimized development zone, which is the best way to protect the environment and put forward the corresponding control countermeasures and guideline.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, the county level ecological function regionalization has just started, the method is not adequate, this study can provide some theoretical reference to other cities.
