The Study Of Chang Zhou Green Space System Planning Based On GIS

With the rapid development of China's economy and the acceleration of urbanization process, the function of urban green space in people's production and livelihood has been given much consideration. The request and goal about"Harmony between human being and nature"has been proposed. From per capital ratio of green space to garden city, from the production of nature resource to ecological garden city, from garden in city to city in garden, all show that people have great expectation for the green space system. At the same time, it sets out a higher level requirement for the planners and designers of green space system. Under this background, Comprehensive analysis by GIS has become a new trend in green space system .Based on the traditional green space system planning, this research introduces the Remote Sensing(RS), the Analytical Hierarchy Process (AHP) and Geographic Information System(GIS). By use of real-time remote image and interpretation technique, providing a great deal of original data. It takes the unique advantages of the multi-factor decision-making while combining the qualitative and quantitative analysis of AHP, combines with the strong spatial analysis functions of geographic information systems, and brings a new attempt to the traditional method of green space planning system. In the green space planning system of Changzhou city, we selected 10 factors, established a weight table of these 10 factors; adopted the analysis of overlay topology of space of the geographic information system, space buffer zone analysis, space network analysis, and other functions. Thus, we made a distributing map of the ecologically sensitive area and green space distribution of Changzhou city, which provided us a scientific basis of green space planning system for Changzhou city.
