On Evolution of Rural Spatial Structure in Western Area under the Background of Urbanization

Under the background of China's balancing urban and rural development and vigorously promoting urbanization,analysis on the evolution of rural spatial structure is conducive to grasp the general characteristics of evolution of rural spatial structure,and to make better planning for the spatial pattern of countryside.Based on Krugman's spatial economic thought,also considering the actual situation of the western region in China,the research analyzes the three levels of differentiation evolution model on the different geographic space distance in the western region of rural spatial structure under the background of urbanization,and builds a theoretical model of rural spatial structure evolution to provide a theoretical basis for the rural spatial structure evolution in western areas.And the model shows that rural spatial structure evolution on appropriate geographic space distance can effectively avoid rural hollowing out and disorderly construction,and eliminate the gap between urban and rural areas,which will better promote the new rural construction in China.
