摘　　要：航班准点率低,航班延误班次多是我国民航业的现状,其中航班延误的扩散严重制约了航空运输业的发展。文章借助模拟航空网络和k-core方法分析航空网络的社团层次结构,通过仿真发现,在延误扩散过程中,初始延误节点的度值越大,所造成的延误扩散的影响也越大;且延误扩散影响最大的是在核心层,核心层节点在网络中与其他节点联系紧密,度值大,故延误扩散的影响最严重;中间层和边缘层的节点大多通过与核心层节点连接造成大范围的延误扩散。The low flight punctuality rate and many delayed flights are the current situation of China's civil aviation.Flight delays seriously restrict the development of air transport industry.In this paper,the community structure of aviation network is analyzed by means of simulated aviation network and Newman fast algorithm.Through simulation,it is found that in the process of delay diffusion,the greater the degree of initial delay node,the greater the impact,and most of the affected nodes are closely related to each other,that is,the delay diffusion is more likely to occur between nodes within the community.
