摘　　要：以武汉市地铁网络为研究对象,基于复杂网络理论分别构建武汉市地铁网络的Space-L和Scape-P网络拓扑结构模型,通过计算不同拓扑结构网络的统计量,分析了武汉市地铁网络的复杂网络特性;研究武汉市地铁网络的鲁棒性,通过制定武汉市地铁网络随机故障和蓄意攻击两种策略,据此量化研究不同节点失效策略对武汉市地铁网络全局效率的影响。结果表明:武汉市地铁网络具有较好的鲁棒性;蓄意攻击对武汉市地铁网络有很大的破坏性,而随机故障则影响较小。Taking Wuhan metro network as the research object, and based on the complex network theory, this paper constructs the Space L and Scape P topological structure models of Wuhan metro network re spectively. By the calculation of the topological structure of the network statistics, the paper analyzes the complex characteristics of Wuhan metro network. In order to study the robustness of Wuhan metro, the pa per generates two strategies of Wuhan metro network, namely, random fallure and deliberate attack, and quantitatively studies the impact of different node fallure strategies on the overall efficiency of Wuhan met ro network. The results show that the metro network in Wuhan has good robustness;deliberate attack has great destructive effects on Wuhan metro network,while random fallure has little influence.
