The Study Of Urban Greenspace Spatial Pattern Rationality

City is the living for citizen. This living space must include urban greenspace,which satisfies the demand of citizen. The spatial Pattern of urban greenspace system has an important relation with living condition of citizen. As decision making of urban greenspace planning is based on single index and subjective judgment,this study tries to set up a comprehensive appraisal system of greenspace spatial pattern through scientific analysis. The study also provides scientific policy recommendations from the view of planning professional,to persuade governments to invest the limited funding and favoring policy on the districts of great demand in order to improve the urban park system spatial pattern step by step.Through the study of concept and function of urban greenspace,this study unveils the facts that the development of society demand drives the function of urban park evolutes and expands. Due to participating on different phase of resolving social issues,urban park system is having more and more important role in the society and at the meantime its spatial pattern is facing more constraints and influences. The study reciews and summarizes a lot of related literature to set the theoretical foundation that is supporting by the location theory of public facilities,the theory of landcape ecology,and the theory of image of the city. With the direction of citizen's demand satisfaction,the study conclude all the affecting factors into three main aspects,namely public facilities provision sub-system,landscape ecological pattern subsystem,and the image of city sub-system. All these will form the comprehensive appraisal index system of urban greenspace pattern system.In the finality, the study concludes the major research outcomes,limitation of research and the suggests the directions of future research.
