摘　　要：为增强对高铁(high-speed rail,HSR)和民航(air transport,AT)网络结构差异的认知,以2019年高铁列车和航班时刻表数据为基础构建无向网络模型,从网络紧凑性、节点中心性、联系强度异质性、网络层次性4个方面对中国高铁和民航网络拓扑结构特征进行比较。结果表明:高铁和民航网络具有较为接近的特征路径长度和集聚系数,但高铁网络密度更大、紧凑性更强;平均而言,高铁网络中节点连通性更好,而民航网络中节点具有更强的中转作用和全局可达性。高铁网络节点“流”联系强度表现出更强的异质性,从东、中、西三大分区来看高铁列车流主要发生在东-东、东-中、中-中部之间,航班流主要发生在东-东、东-中、东-西部之间。从核心边缘层次结构来看,高铁网络中与桥接层相关联的列车流占比较高,民航网络中与桥接、边缘层相关联的航班流占比较高。To enhance the knowledge of structural differences between high-speed rail(HSR)and air transport(AT)networks,topological characteristics of the two networks were compared in terms of network compactness,node importance,connection heterogeneity and network hierarchy.The undirected nerwork model was constructed based on the 2019 high-speed railway train and flight schedule data.The results show that similar characteristic path length and clustering coefficient are presented in the two networks,and network density and compactness of HSR network are larger.On average,node connectivity in HSR network is higher,while bridging roles and global accessibility of nodes in AT network are better.Stronger heterogeneity can be found in the distribution of train flow in HSR network compared with distribution of flight flow in AT network.Train flow in HSR network are mainly distributed in east-east,east-center,center-center regions,while flight flow in AT network are mainly distributed in east-east,east-center,east-west regions.The proportion of train flow related to the bridge layer in HSR network is higher,while the proportion of flight flow related to the bridge and periphery layers in AT network is higher.
