On Evolution Of Rural Spatial Structure In Western Area Under The Background Of Urbanization

All the theoretical research serves to the practical development. According to the process of urbanization, with every step into a new stage, the evolution of regional special structure experienced a unstable state, either from diffusing to centralizing or from centralizing to diffusing, exist in every aspect of the space. Along with the advancement of urbanization, the rural spatial structure evolution of the western China is experiencing a similar adjustment process, but due to lack of study in the western region of rural spatial structure evolution theory, so the rural spatial structure evolution of the western region is still in a relatively disorder, chaos and non-equilibrium state.This article focus on the rural spatial structure evolution in western area on the background of urbanization,On the basis of regional spatial structure evolution theory, based on the practice in the western region, in view of the urbanization process in the Midwest rural problems of spatial structure evolution, put forward the geographic space distance and small towns to scale the near, middle and far spatial structure optimization model of three kinds of village.Then introduce Krugman’s space economic thought, to build the western region rural spatial structure evolution of theoretical model, to explore the Midwest rural urbanization characteristics, trend and mechanism of the spatial structure evolution, finally it is concluded that the urbanization process in the central and western regions of rural spatial structure will evolve from disequilibrium to equilibrium, small city- town- the center village three level structure.Center village will become the focus in the western region rural spatial structure evolutionfrom the unbalanced to balanced, and finally on the basis of the spatial structure to put forward to promote the western region rural equilibrium evolution policy Suggestions.This paper divides into five parts:The introduction part involves the research background, research significance, research method and research framework of this thesis.The second part maintains the theory analysis, and defines relate concepts, the spatial structure and the spatial structure evolution theory, the village and town spatial structure evolution theory, provides the theory support to the following rural spatial structure evolution analysis and the rural spatial structure optimization.The third part is about the situation of rural spatial structure evolution in the western region on the background of urbanization. It analyze the rural spatial structure evolution of the western China from three aspects. Include the influence of urbanization of rural spatial structure evolution, the problems existing in the rural spatial structure evolution and the pattern in the evolution of spatial structure in the western region.The fourth part is about the construction of rural economic spatial structure evolution model under the urbanization perspective. Based on the regional spatial structure evolution of micro main body, the thorough analysis of the rural economy microscopic dynamics and evolution mechanism of spatial structure evolution, and on this basis, the construction of rural economy spatial structure evolution of the model.The fifth part is recommendations about rural spatial structure optimization. Finally on the basis of above research results, put forward the Rural spatial structure optimization Suggestions.The conclusion part forecasts the further evolution trend of rural spatial structure on the basis of summarizing research attainment.
