以城市非农业人口作为城市质量,以空间直线距离分别在距离衰减参数b=1和b=2情况下作为空间联系的衰减方式,采用重力引力模型对全国地级城市进行了城市网络的构建,选取最大城市联系强度网络结构进行复杂性分析,借鉴复杂网络分析中的度、网络结构熵及网络标准结构熵等概念研究城市体系空间组织,这样将地理空间约束机制的概念引入到统计物理所忽略的复杂网络研究中,也为城市体系研究带来了新视角。分析得出了1990年代以来＂大集中、逐步小分散＂的城市网络组织的基本结论,最后对全国城市体系进行了空间等级划分。

We construct urban networks from prefecture level based on non-agriculture population and spatial straight-line distance and we choose the distance decay parameter b that is equal to one or two.This paper analyses the complex characteristics about China＇s urban networks on the ground that maximum in linkage strength among cities.The concepts in the research field of complex networks analysis like degree,network structure entropy,network standard structure entropy,etc.are introduced into urban system studies,which is a new perspective in urban studies on the one hand.And on the other,we also introduce geographical spatial constraint into complex networks in statistical physics.The conclusion is that some important cities are polarizing from national level and some cities are gradually dispersing from regional level in China＇s urban system.At last,hierarchical relations in China＇s urban system are summarized by GIS tools.
