摘　　要：运用复杂网络理论,构建了中国航班流网络,并以平均路径长度、簇系数、最大连通子图尺寸以及整体效能下降率为度量指标,研究其在航线失效模式下的抗毁性。结果表明,中国航班流网络对蓄意航线攻击具有脆弱性,特别是攻击介数较大的关键航线时,网络抗毁性下降非常快,几乎造成东西部地区链接的断裂。基于权重攻击下的网络抗毁性下降速度较介数攻击慢,但由于平均路径长度增大,从而使得经济成本上升。所以对于这类介数和权重较大的重要航线都需要确保其安全运行,并不断优化中国航线网络结构。Using complex network theory, the flight flow network is constructed and the following indices such as average path length, clustering coefficient, the decline rate of maximum connected subgraph size and overall efficiency are taken to analyse network survivability based on the failure of flight routes. The results show that the flight flow network has vulnerability to the deliberate route attack, especially the key routes with great betweenness, the network survivability decreases very fast, resulting in the fracture of the east-west link. The decline rate of network survivability under the weight of attack is slower than the betweenness attack, but because of the increasing average path length, the economic costs rise. So the routes with great betweenness and weight need to be ensured safely operation, and the structure of route network needs to be optimized continually.
