COMPARATIVE STUDY ON SPATIAL STRUCTURE CHARACTERISTICS OF CHINESE TEN TOP URBAN AGGLOMERATION
运用地理软件和空间分形理论，比较中国十大城市群的空间结构异同与变化规律，发现整体呈倒T型结构，核心城市沿公路铁路向外扩散，未来发展中西部城市群将出现挤压效应。
Urban spatial structure in China to promote urban agglomeration strategy implementation effect evaluation and further development is of great theoretical and practical significance.With comprehensive application of geographical software and spatial fractal theory,from the fractal dimension and the regression equation of spatial structure of China's ten top urban agglomeration,the article has explored the similarities and differences and the changing laws of spatial structure characteristics of China's ten top urban agglomeration.It is found from the research that the whole group of Chinese urban agglomeration showed inverted T-type structure.And each urban agglomeration is highly concentrated in a geographical factors,the core city is mainly spreading outside and extending as the highway and railway lines for diffusion axial.The future development of urban agglomeration is in the Midwest.Along with the urban agglomeration strategy propulsion and the increasing of the urbanization process,urban agglomeration can reduce the expansion of land,and then make the city groups and between urban agglomeration appear certain squeezing effect.
