摘　　要：为探究成渝地区双城经济圈交通一体化建设过程中轨道交通的作用,构建成渝地区道路与轨道双层交通网络模型,分析轨道交通网络演化及对综合交通复杂网络特性的影响。研究结果表明,2015—2021年,综合交通网络节点与连边不断增加,节点平均度逐年提升,孤立节点逐渐减少,网络复杂度逐步提升并向均衡化发展;轨道交通网络的加入增强了原有道路关联,并使得站点重要性顺序发生变化,轨道交通站点在网络中重要性显著提升;轨道交通站点和线路的增加引发社区数产生先减少后增加的变化,简化网络显示社区数由5降为4,局部地区社区归属发生变化;不同承载能力下,网络性能受动态的网络介数中心性破坏策略损害较大,基于节点度值的破坏策略在干扰前期破坏性更为明显且强烈。To explore the role of rail transit in the transportation integration of the Chengdu-Chongqing economic circle,this paper constructed a two-layer traffic network model of road and rail of the Chengdu-Chongqing area to analyze the evolution of the rail transit network and its influence on the complex network characteristics of integrated transportation.The results show that:①The number of nodes and edges in the integrated transportation network keeps rising,showing an annually-growing average degree of nodes and gradually-decreasing isolated nodes.The network complexity is becoming more balanced at the same time as gradually increasing.②The addition of a rail transit network strengthens the connection of existing roads and changes the importance order of stations.The importance of the rail stations in the network has increased significantly.③The increase of rail stations and lines causes the number of communities to decrease first and then increase.The number of communities in the simplified network decreases from 5 to 4,and the community affiliation of some areas has changed.④Under different carrying capacities,the network performance is more compromised by the dynamic disruption strategy of network betweenness centrality,with the strategy based on node degree value showing stronger and more obvious damage to the network performance in the early stage of interference.
