摘　　要：为提高我国高速铁路网络(HSRN)面对突发事件的抗毁性和可靠性,保障HSRN平稳而高效率地运营,基于复杂网络理论,构建3个发展时期的HSRN拓扑结构,探究网络的拓扑特性和发展趋势。利用站点重要性综合评价指标挖掘HSRN的重要站点。通过计算网络效率和最大连通子图,分析HSRN在随机攻击和蓄意攻击下的表现。结果表明:我国HSRN在中期发展阶段是以增加网络连通度为主,在长期发展阶段是以丰富集聚效应为主;站点重要性排序显示,武汉、天津、长沙和襄阳将成为不同发展阶段的重要站点;HSRN对随机攻击有鲁棒性,对蓄意攻击有脆弱性。In order to improve the invulnerability and reliability of HSRN in the face of emergency and to ensure smooth and efficient operation of HSRN,topological structures of China ＇s HSRN in three periods were built based on complex network theory,network characteristics and evolution rules were studied.Integrated station importance evaluation index combining degree and betweenness was given to discover the important stations. Through the analysis of network efficiency and relative size of the largest connected subgraph,the HSRN ＇ s performance was studied under random and malicious attacks. Results show that China＇s HSRN adds network ＇ s connectivity in the mid-term while enriches agglomeration effects in the long-term,that Wuhan, Tianjin, Changsha and Xiangyang are the important stations in different development stages,and that HSRN possesses robustness under random attack and vulnerability under malicious attack.
