摘要
复杂网络理论为研究网络的拓扑结构和统计特征提供了新途径。该文将复杂网络理论应用于城市路网,首先探讨了复杂网络的统计分析方法,选择特征路径长度、聚类系数、节点的度分布、网络同配/异配性、网络弹性作为度量指标。在总结分析现有路网建模方法基础上,采用基于角度综合的对偶方法进行路网建模。最后以长沙市路网为例,利用ArcGIS和MatLab分别处理路网空间数据和计算统计指标,分析其小世界特性、无标度特性以及同配异配性、网络弹性等结构特性,得出了一些有益的结论。
Complex network theory provides a new approach for exploring the topological structure and statistical character of urban street networks.In this paper,complex network theory is applied to urban street networks.Firstly,some approaches for analyzing complex networks are described.Some indexes such as characteristic path length,clustering coefficient,degree distributions,assortative or disassortative coefficient,network resilience are choose.Furthermore,the methods of the modeling of urban street network are summarized,and the angle-based dual method is used.Finally,taking Changsha street networks as an example,processing spatial data and statistical index based on ArcGIS and MatLab,some complex network properties of Changsha street networks are analyzed and some conclusions are made.
