City Fringe Area Space Succession And Mechanism Research In Westlake District Of Hangzhou

With the rapid development of urbanization, urban function spillovers, the space to the suburbs spread, the city fringe area of urban and rural as a transition function region, the urban spatial expansion influence the most sensitive areas. Due to the city center and the fringe area of land use in different ways, different benefit main body, the formation and development mechanism difference, marginal zone in the complicated relationship between the space form constantly changing, its present problems more and more complicated. The edge for the city spatial expansion process and mechanism as well as the fringe area to explore the root of the problem, has become the focus of research at present scholars. The Hangzhou Xihu district of Hangzhou city as an important part of the urbanization and urban spatial expansion in recent years to speed up, to the edge of the city the research result is useful to the realization of rural and urban areas and the "five one", promote the coordinated development of urban and rural areas.Based on a large number of literature reading, on the basis of domestic and foreign cities in the edge of the definition, decision method, space types and spatial evolution theory were summarized, clear the definition of the edge area research subject and the main fringe area definition and the advantages and disadvantages of the method, which is elements edge area spatial decision method to provide support. Then introduces in detail based on factor analysis of the edge area spatial decision method, and this method to the edge of the city of space scope definition. Then in the fringe area based on the results of determination, from the edge area of city space evolution characteristics, the urban fringe area space types and the edge area spatial prediction three aspects, the spatial pattern of evolution were analyzed. Finally from the power mechanism, the support mechanism and coordination mechanism in three aspects, summarizes the Hangzhou city fringe area in2000-2010and spatial evolution mechanism.
