THE SPATIAL STRUCTURE OF URBAN AGGLOMERATIONS SYSTEM IN CHINA BASED ON SPACE INTERACTION
利用ESDA技术分析中国城市群的空间交互，发现其空间分布具有显著的空间依赖和正相关特征，2000年后系统进入结构稳态，并结合引力强度量化分析空间分布轴线。
Space interaction between Urban Agglomerations is the basis of spatial structure of the system of Urban Agglomeration.Based on the use of ESDA techniques to analysis the spatial interaction indicate that the spatial distribution of Urban Agglomerations has distinct characteristics of the space-dependent and positively correlated.It is obviously that the Urban Agglomerations system is in the phase of structural steady-state after 2000.Combined with the gravitational strength of the largest Urban Agglomeration excavation analysis system to quantify analysis the spatial distribution of the axis,raise the concept of Poisson distributionshape.
