Analysis of Directional Weighted Structure of Route Network in Chengdu-Chongqing Airport Group
The Chengdu-Chongqing airport cluster is a major strategic deployment of the construction of Shuangcheng econom-ic circle in Chengdu-Chongqing area.In order to explore the complexity of the route network topology structure of the Cheng-du-Chongqing airport cluster,the complex network theory is used to build a weighted route network model,calculate the basic sta-tistical index,centrality index and network efficiency of the route network,and analyze the network structure.The results show that the Chengdu-Chongqing airport cluster has obvious small-world characteristics.Tianfu Airport and Jiangbei Airport are the actual hubs of the airport group,but the competition of air routes is serious,and the overlap degree of air routes is high.Although each branch airport can relieve hub pressure to some extent,its hierarchy is not clear and its development is slow.The connection be-tween hub and non-hub is not close and the degree of centralization is low.Dazhou Airport and Wushan Airport can be developed as close sub-hub airports respectively.When the network is attacked,the network efficiency is low.Based on the above problems,sug-gestions are proposed.
