摘　　要：机场作为重要的基础交通设施,对于地方商业发展和居民生活质量意义重大,航线网络的连通性水平决定了航空运输的服务水平.本文通过运用社会网络分析方法对中国国内航线网络进行分析,通过计算其密度、中心度(程度中心度;接近中心度;中介中心度)、切断点,分析国内机场国内航线的连通性水平;并对切断点进行扩展研究,计算节点删除对连通性水平的损失,并将损失分为直接损失和间接损失.研究结果表明,中国国内航线网络整体连通性水平较低,东西部连通性水平差异较大,同时西部地区也存在特色网络结构,整体网络对首都机场依赖性很强,抗毁能力弱.As an important traffic infrastructure,the airport is of great significance for local business and residents.The connectivity level of the air network represents the level of air transport services.This paper analyzes the air network of China based on social network analysis,by calculating the density,centrality,cut off point and the total loss of every deleted airport.It makes a conclusion that the connectivity level of domestic air network of China as a whole is relatively lower and the east-west differences in the connectivity level is obvious.There is also a characteristic network structure exit in some particular regions of the west.Meanwhile,the whole network greatly relies on the Beijing Capital International airport.
