四川省航空旅游网络空间特征及其结构优化研究

运用程度中心性、接近中心性和中介中心性3个空间向量指标,分析四川省2006年和2020年航空旅游网络空间结构特征,评估四川省航空旅游网络空间结构特征的变化。研究发现,2020年四川省航空旅游网络连接性和完备性将有明显改善,但网络冗余度和制约度有恶化迹象。因此,提出四川省航空网络优化建议:1)除强化成都枢纽地位外,还应加强九寨等网络次级中心建设;2)加强旅游缓冲区与成都的航线联系,加大旅游目的地机场的关联度;3)旅游资源禀赋对于航空旅游网络空间结构有着重要影响,因此要解决机场边缘化问题,必须加强旅游资源开发,形成互补效应,才能逐步发展成为缓冲区域甚至是进出口通道区域。

Research on Aviation Tourism Spatial Structure in Sichuan and Its Optimization

Based on the practical value of degree centrality,close centrality and betweenness centrality,this paper analyzes space structure character of aviation tourism system in Sichuan and measures the links among tourism destinations,which symbolize the importance,accessibility and intermediate of aviation tourism system in Sichuan respectively.Based on the results of network analysis,the destinations can be divided into core destinations,buffer destinations and periphery destinations.Therefore,the authors propose some suggestions of aviation network optimization for Sichuan:1) besides to strengthen Chengdu regional hub,Jiuzhai and other network sub-center must be strengthened;2) to enhance the relation of tourism buffer zone and Chengdu route,increase the correlation of tourism destinations to the airport;3) it is necessary for solving the problem of airport marginalization,and to strengthen the development of tourism resource and develop a mutually complementary effect so that the relative tourism destination can gradually develop into a buffer region or even regional access.
