摘　　要：复杂网络是指具备复杂拓扑结构和动力学行为的大规模网络。近年来,随着复杂网络的小世界属性和无标度性质被揭示,复杂网络研究开始受到众多学科研究人员的关注,并逐步延伸到航空网络领域。在复杂网络理论的基础上针对我国长三角地区航空网络进行拓扑结构分析,主要运用了度分布、聚集系数、平均路径长度等指标,结果表明其具有明显的小世界特性和无标度性。通过3个不同的中心势指标发现该网络的中心化程度较高,具有以上海、南京等地机场为中心的枢纽辐射式航线网络的特性。此外,通过记录蓄意攻击下的网络效率的变化情况分析出该网络抗毁性较差。Complex network is a large-scale network with complex topology and dynamic behavior.In recent years,with the small-world and scale-free nature of complex networks being revealed,studies of complex networks have at⁃tracted the attention of many researchers and gradually extended to the field of aviation networks.Based on the theory of complex network,this paper analyzes the topological structure of the aviation network in the Yangtze River Delta re⁃gion of China,mainly using degree distribution,clustering coefficient,average path length and other vectors.The re⁃sults show that it has obvious small-world and scale-free characteristics.Through three different centrality indexes,it is found that the network is highly centralized and has the characteristics of hub and spoke network centered on air⁃ports in Shanghai,Nanjing,and other places.In addition,it is found that the network has poor destruction resistance by recording the changes of network efficiency under intentional attack.
