基于复杂网络的机场群航线网络动态特征分析

随着航空运输和区域经济一体化的快速发展,我国已形成京津冀、长三角和珠三角三大典型机场群。文章以三大典型机场群为研究对象,构建基于滑动时间窗的航线网络拓扑结构,运用复杂网络理论分析机场群航线网络动态特征和同构性。研究结果表明,机场群航线网络具有无标度和小世界网络特征,并表现出显著的波峰和波谷动态性,并且长三角机场群的航班集中度分布明显高于其他两大机场群。文章首次从航线网络视角,运用Dice相似系数衡量了机场群内部各机场之间航线网络同构性程度。

Dynamic characteristics analysis of aviation network in multiple-airport-systems based on complex network

With the rapid development of air transportation and regional integration,China has formed three typical airport groups:the Beijing-Tianjin-Hebei,the Yangtze River Delta and the Pearl River Delta.Taking three Chinese typical airport groups as the research object,an aviation network topology structure based on sliding time windows is constructed.A study of the dynamic characteristics and isomorphism of airport group is conducted by the complex network theory.The result indicates that Chinese aviation network distribution has obvious scale-free and small-world characteristics,as well as significant dynamic characteristics of peak and troughs.The distribution of flight concentration in the Yangtze River Delta Airport Group is significantly higher than that of the other two major airport groups.Moreover,it’s the first time to use Dice similarity coefficient to measure isomorphism between multi-airport systems from the perspective of aviation network.
