从复杂网络角度对2001—2010年我国航班流网络结构进行实证分析.通过计算网络结构的统计指标，验证了该网络具有小世界特性和无标度特性，并构建了最大连通子图尺寸下降率和整体效能下降率指标,对其进行抗毁性分析.根据不同年度对比分析，发现我国航班流网络抗毁性有逐年提高的趋势，但却更依赖于几个关键机场.通过各种攻击方式的对比分析，得出我国航班流网络对随机攻击表现出较强的鲁棒性，而对恶意攻击却非常脆弱.整个网络的可靠性主要由少数重要机场决定，需要重点确保这类机场安全高效运行，并向多枢纽系统发展.

Empirical Analysis on Flight Flow Network Survivability of China

From the aspect of the complex network, this paper makes empirical analysis on the flight flow network structure of China from 2001 to 2010. The calculation of network statistical indicators reveals that the flight flow network has the small world characteristics and the scale free property. Then two indicators, the decline rate of the maximum connected sub graph size and the decline rate of the overall efficiency are proposed to study the network survivability. Comparative analysis is conducted for different years, which indicates that the survivability of China flight flow network has an increasing trend and the network is more dependent on several key airports. Comparative analysis is also made for various attacks, which demonstrates that the flight flow network has strong robustness against random attack, but is vulnerable to deliberate attack.The reliability of the entire network is dominated by a few major airports,thus,the safe and effective operation of these airports should be ensured and it is essential to build some multi hub systems in the future.
