Evaluation And Planning Of Green Space System In Mining City

Green space system is important part of urban ecological system, playing a decisive role in the improvement of urban ecological environment. Because of its special history with established as mining activities, mining cities were lack of long-term effective planning in urban construction, with crowded buildings, few green space and serious environmental pollution. Currently,many mining cities in china爱are facing resource-exhausted,Eagerly have entred into economic-transition. The deteriorative ecological environment of mining city not only affects people's daily lives and physic-mental health but also becomes pertinacious illness to economic-transition and development of the city.The present status of mining city's green space system has been evaluated and analyzed in this paper. Based on Jiaozuo evaluation,a new planning of Jiaozuo City's green space system is made. The major elements are as follows:(1) Based on the theoretical analysis, combining with the particularcase of mining City, the theory and method of evaluation and planning for green space system of mining city are discussed.(2) It has been analyzed environmental pressure influencing factors of mining city's green space system, to set up environmental pressure evaluation index system of mining city with analytic hierarchy process (AHP), and applied to evaluation and analysis of Jiaozuo City's green space system.(3) It has been classified mining city's green space, according to the feature of mining city's green space system, selecting diversity, fragmentation, dominance, corridor density, connectivity etc. as landscape ecological indexes for mining city's green space system. Through interpretation and on-the-spot investigation to latest remote-sensing image of Jiaozuo,it evaluated and analyzed Jiaozuo City's green space patten.(4) On the basis of disaster prevention and evacuation function of mining city's different types green space analysis, it has been defined the effective disaster prevention space. Through extracting patches which have emergency shelter function in Jiaozuo city's green space,It analyze and evaluate emergency shelter spaces'pattern and function in Jiaozuo city.(5) Based on sufficient analysis to Jiaozuo City's green space system,considering Jiaozuo City's need to green space in future urban development,a new planning of Jiaozuo City's green space system is gotten by applying landscape-ecology theory.
