The Comparison Research of China´s Aviation Network´s Key Nodes

In accordance with the principle of centrality indices were selected, degree, closeness, node betweenness and flow betweenness, to progress the centrality of CAN (China´s Aviation Network) and rank the degree of importance of nodes in CAN. The result shows that: in the four treatment results, the application of node betweenness index made the best; its centrality degree is 96.92%. And by comparing the centrality degree value based on different indices of the CAN network, got the major Chinese aviation network nodes are Beijing, Urumqi, Guangzhou, Shanghai and Kunming.
