基于复杂网络的航空货运枢纽城市研究

摘要

Adopted the complex network analysis method, by studying the aviation cargo network structures from 2004-2009, the general development trend of the domestic cargo network waspresented. A core-peripherymodel was constructed to select the core hub cities and the scale-free characteristics of the air cargo network was proved. Then a purposeful attack way was taken to discuss the network survivability, in which one and three hub cities were respectively removed and the network statistical indexes of the cargo system, such as average route length, cohesive power index, node degree, etc., were comparatively analyzed. The results showed that attacking the hub city would seriously affect the connectivity and cohesion of the whole cargo network.%采用复杂网络分析方法，通过对2004-2009年航空货运枢纽网络结构的实证研究，呈现我国航空货运的整体发展趋势，建立了核心一边缘模型，筛选出核心货运枢纽城市并论证了航空货运网络的无标度特性。进而采取蓄意攻击方式对网络抗毁性进行分析，分别移除航空货运系统中1个、3个枢纽城市，对货运系统的网络平均路径长度、凝聚力指数、节点度等统计指标进行对比，结果表明对枢纽城市的攻击，将严重影响整个航空货运网的连通性和集聚性。
