Study On Optimization Of Spatial Structure Of The Three Major Urban Agglomerations In The Middle Reaches Of The Yangtze River Area

The development progress of the city clusters in the world expresses that urban agglomeration has become the most active areas in global economic life, and made great contribution to the economic growth of the country. As an advanced regional spatial form, it’s a basic regional element in the course of globalization and region integration. The development of city clusters always goes with the change of spatial structures of city clusters, in the same time, the optimization of the spatial structure will improve the whole function. In-depth study of the spatial structure of the city clusters, you can better promote the development of urban agglomerations.Wuhan city circle, the Changsha-Zhuzhou-Xiangtan city cluster and the Poyang Lake Ecological Economic Zone of the middle reaches of the Yangtze River area consisting of a relatively complete middle reaches of the Yangtze River City Cluster, This paper take three major urban agglomerations in the middle reaches of the Yangtze River region as research object, and the spatial structure as the starting point, integrating theory with practice. The spatial structure situation and the formation mechanism of the three major urban agglomerations are analyzed. From the angles of time and space to predict the future trend of the urban agglomeration. Through the integration planning, the three major urban agglomerations in the future will be the inter-provincial domain, multi-center, network, and the eco-city cluster, This puts forward a concrete optimization measures in order to achieve integration, by multi-improvement and perfect measures from the form, industries, transport and ecological development.This article is divided into three parts:prologue, text and epilogue. The first chapter is an introduction, As the opening badge, the first chapter mainly introduces the background and significance of selecting the topic, introduces the current domestic and international spatial structure of urban agglomeration, and reviewed research content and key issues. The main body contains three chapters, The second chapter discusses spatial structure situation of the three major urban agglomerations, studying the evolution processes and evolution character, And space evolution pattern of the three city groups were analyzed. The third chapter points out the dynamic formation mechanism, which conations regional interactive development, spatial cooperation and competition, urban and rural interaction, environmental constraints. The fourth chapter analyzes the development trend of the spatial structure of urban agglomeration, the three city groups will become multi-polar collaboration, network development, eco-city cluster. Chapter five is the focus of this article, there are four aspects to optimize the space structure which conations form space, industrial space, traffic space and ecological space to guide the strategy. The third part of the conclusion points out the future of this research, introduced the innovation of this paper and inadequacies...
