摘　　要：运用复杂网络理论,对以成都市为例的城市公共交通复合系统网络以及两子系统网络进行了相关拓扑特性与抗毁性分析。分析结果显示,以成都市为例的地铁-公交复合网络及其子网络均为具有无标度特性的小世界网络,在L、P两种空间中均表现出随机袭击下的鲁棒性与蓄意袭击下的脆弱性,且节点的抗毁性低于边的抗毁性;同时在相同袭击条件下,复合网络的抗毁性均优于地铁子网络与地面公交子网络。Based on the complex network theory, the topological characteristics and invulnerability of urban public transit compound network and its sub-networks are analyzed. The simulation results indicate that subway- bus compound network of Chengdu city and its sub-networks are scale-free and small-world networks, which show robustness to random attack and vulnerability to intentional attack with topological structures described in space L＆ , and the invulnerability under node attack is lower than that under edge attack. Meanwhile, the invulnerability of subway-bus compound network is higher than both the subway network and bus transit network.
