URBAN SYSTEM SPATIAL STRUCTURE AND ITS FRACTAL CHARACTERISTIC OF THE YANGTZE DELTA
基于分形理论，计算了长三角城市群空间结构的聚集维数、网格维数和空间关联维数，发现其具有分形性质，表明分形理论适用于分析该区域的空间结构。
Based on the fractal theory,the paper calculates aggregation dimension,grid dimension and spatial correlation dimension of the spatial structure,and finds out that the spatial structure has the fractal properties,so the paper thinks that fractal theory can fit to calculate and analyze the spatial structure of Yangtze Delta Interlocking Metropolitan Areas.According to the results of calculation and analysis,the paper draws the conclusions that spatial structure of urban system in Yangtze Delta Interlocking Metropolitan Areas presents distinct convergences character.
