XU Mei; LIU Chunla. Research on Optimizing the Spatial Structure of the Pan Changsha,Zhuzhou and Xiangtan City Cluster, Tropical Geography, 2009, 29(4):356-361. Abstract: Using the typical mode and structural features of city clusters both at home and abroad for reference,the spatial structure of the pan-CZT city cluster was analyzed in this paper,in which the urban density theory,the sub-dimensional spatial structure theory of city clusters and the space interaction theory were used.Many features of pan-CZT city clusters were shown,such as great urban density,the coincidence between population distribution and urban distribution,obvious directivity of city distribution ...
