中文摘要：

城市群之间的空间相互作用是城市群体系空间结构赖以形成的基础,利用引力模型思想和ESDA技术在时间截面上对城市群之间空间相互作用的流量及流向的分析发现：中国城市群体系空间结构与空间相互作用具有明显的正相关性,其空间结构的空间依赖性特质明显,呈现出空间集聚特征;2000年后中国城市群体系空间结构进入＂结构稳态＂期;将最大引力分析与ESDA分析结合,量化挖掘城市群体系空间分布轴线,发现城市群体系空间结构的＂泊松分布＂形态明显。

英文摘要：

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 distribution＂shape.
