武汉市多中心发展格局演变研究

Research on the Evolution of Polycentric Pattern in Wuhan, 1995-2010

城市中心体系的发育状况极大程度上影响着整体城市的运行发展。多中心城市的发展格局研究对城市的空间可持续发展具有科学引导意义。本文基于改进的引力模型和社会网络分析方法,分析了武汉的多中心网络发展格局及其演变特征。结果显示:武汉市多中心网络发展迅速,各中心间已形成紧密的网络状关联,且主中心发展动力强劲,但网络内中心节点间中心性不均衡。最后,从提升与优化网络系统的角度出发为促进武汉多中心发展提出了相关建议。

The development of city is largely affected by the growth of urban center. Research on polycentric city structure is significant in scientifically guiding the sustainable development of urban space. Based on the application of improved gravity model and social network analysis, this paper measures the polycentric network of Wuhan and its evolution of polycentrie pattern. The results indicates that the number of nodes in polycentric network increases obviously, a close network connection between centers has formed, the main centers are developing strongly, but the other centers are much weaker. At last, proposing some suggestions for the polycentric development of Wuhan to promote and optimize its polycentric network system.
