Research On Metropolitan Cluster Space Mechanism And Structure Model In Big Cities

With the urban regionalization and regional urbanization, cluster space type, a newurban spatial structure appears in some metropolitan area. This new urban space can becalled Metropolitan Cluster Space based on the theory of urban planning and urbangeography. The paper chooses the word Cluster to explicate the new development ofmetropolitan spatial structure, and explore the mechanism and model of the MetropolitanCluster Spatial Structure. In a specific phase in China, it is an attempt to analyze themetropolitan spatial development.This paper chooses the cases of Wuhan, Nanjing and Changsha as a basic researchplatform from the positive analysis, to summarize the process characteristics of themetropolitan spatial expansion, and to interpret the mechanism of the Metropolitan ClusterSpace. Meanwhile, the elements features of Metropolitan Cluster Spatial Structure can beconcluded. Based on the above, the model of Metropolitan Cluster Spatial Structure comesto a conclusion.This thesis includes the following four parts:The first part is to analyze the process characters of metropolitan cluster spatialdevelopment. Starting from the cases of Wuhan, Nanjing and Changsha, the articledescribes the objective process of metropolitan cluster spatial development since1990s,and summarizes the process features from the stage, the mode of spatial development andthe development of function space respectielyThe second part is to research on the growth mechanism of Metropolitan ClusterSpace. In this part, the framework including basic level and social level, to explain themechanism of metropolitan spatial development, is proposed in the view of sructuralism.So the particularity on the growthing of Metropolitan Cluster Space can be reached.The third part is to summarize the elements features of Metropolitan Cluster SpatialStructure. The features of cluster-style space can be summarized by analyzing theelements, which includes the layout of public service building, the network of transportsystem, along with the green and ecologic framework and urban land use framework.The last part is to research on the model and application of Metropolitan Cluster Spatial Structure. Based on the analysis above, the concept, the basic model and the types,the characteristics, the measures of Metropolitan Cluster Spatial Structure are explained.At the end of this article, the optimizing measures of Metropolitan Cluster SpatialStructure are proposed.
