基于1989-2010年武汉城市圈城乡路网拓扑空间数据库,引入复杂网络统计特征量和空间自相关分析方法,对武汉城市圈城乡路网拓扑空间关联性及其演化进行实证研究。发现全局上武汉城市圈城乡路网各拓扑统计指标间形成良好的空间关联性,存在一定的空间集聚性,并且随着时间的推移这种空间集聚态势呈现波动式变化;局域上,空间集聚模式总体上维持良好的稳定机制,基本呈现核心圈的高值指向性和外围圈的低值指向性特征,武汉市基本成为拓扑变量的高值集聚中心;同时这种空间集聚模式也表现出空间结构的动态性变化,各种关联类型集聚形态出现"渐变"-"突变"的交替演化。

The 21st century is the century of complexity, as a powerful tool for the study of the complexity science and complex systems, complex networks provides a new perspective for the study of complexity. Transportation network is a typical, open and complex giant system, its topology complexity has been a hotspot in the field of complex network research. But both abroad and domestic, from the perspective of geography, the comprehensive analysis of the traffic network space complexity research is relatively weak, and the traffic network topology space correlation almost empty. Therefore, taking Wuhan metropolitan area as an example, based on its urban-rural road network topological spatial database, introducing the complex network statistical characteristics and spatial autocorrelation models and then spatial correlation and its evolution on topological structure of urban-rural road network(URRN) within the last 20 years in Wuhan metropolitan area are performed. The study reveals that the global spatial autocorrelation of URRN is well and there has some spatial agglomeration which presents the fluctuation variation with the lapse of time. On local level, the spatial gathering pattern maintains a good stable mechanism as a whole, basically presenting the high value directive property of central area and the low value directive property characteristics of peripheral area. Wuhan city has become the gathering center with high value of topological variables. Overall, by using the spatial autocorrelation models, this article explored the topological space correlation of road network in Wuhan metropolitan area based on the past research experience on complex traffic network, and its evolution characteristics were discussed.
