Comparion and analysis of spatial structure of two major urban agglomeration in the central area of China

Changsha-zhuzhou-xiangtan urban agglomeration and Zhongyuan urban agglomeration are two important central dense regions in the central area of China. This paper adopts some methods such as comparative analysis, establishment abstraction mathematical model by the fractal theory to comparison and analysis the spatial structure of the two urban agglomeration, and strive to find the advantage and disadvantage of the growth of urban agglomeration in difference mode of urban agglomeration, and puts forward the optimization tactics of urban agglomeration development.
