摘　　要：建立大北极综合交通运输体系对我国制定北极战略制定以及优化与整合交通运输布局有着重要的参考价值。以大北极范围内各国交通枢纽城市为节点,以节点可提供的运输方式为权重构建大北极综合交通网络,并应用复杂网络理论与社会网络分析法,对网络的整体特性以及节点中心性进行分析,并应用TOPSIS法分别计算节点的综合中心度,识别网络中的核心枢纽城市。结果表明:(1)考虑运输方式的大北极综合交通运输网络呈现复杂有序的特点,具有较小的平均路径长度与较大的聚类系数,网络的无标度性明显,其小世界性也已初步展露;(2)上海、巴黎、伦敦的综合中心度排名靠前,其可提供的运输方式丰富,运输线路覆盖率高,在网络中的连通性和枢纽能力优秀,属网络中的骨干枢纽城市;(3)部分枢纽城市可提供的运输方式有局限性,制约了其在大北极综合交通运输网络中的发展势头。The comprehensive transportation network of the Pan Arctic is constructed by the nodes of transportation hub cities,and weighted by transportation modes provided by nodes.According to the complex network theory and social network analysis method,the overall characteristics and node centrality in the network are analyzed,and the comprehensive centrality of nodes is calculated by the TOPSIS method to identify the core hub cities in the network.The results show that:(1)Considering the mode of transportation,the Arctic comprehensive transportation network presents the characteristics of complex and orderly,with a small average path length and large clustering coefficient.The scale-free nature of the network is obvious,and its small cosmopolitan nature has been initially revealed;(2)Shanghai,Paris and London are among the top cities in terms of comprehensive centrality.They are the backbone hub cities in the network with rich transportation modes,high coverage of transportation lines,excellent connectivity and hub capacity;(3)There are some limitations in the transportation modes available in some hub cities,which restrict their development momentum in the Arctic comprehensive transportation network.
