摘　　要：航空运输作为现代社会重要的交通运输方式,与城市发展紧密相关,对航空运输网络的研究已成为分析城市体系格局的重要视角.基于2016年全国207个主要机场的航空客运数据,运用ArcGIS、社会网络等分析方法,探讨了航空网络视角下的中国城市体系等级结构与空间联系.研究发现:从等级结构上看,全国共分为全国性中心城市、区域性中心城市、次区域性中心城市和地方性中心城市4个等级,城市数量自上而下递增,以北京、上海、广州、成都4个城市为中心,全国城市体系形成近菱形网络结构;从空间联系上看,排名前十位的城市多位于东部沿海地区,全国城市的空间联系具有明显的东西差异性,东部地区具有更高的联系强度,长三角城市群为全国的核心,全国呈现以城市群为空间载体的多中心网络结构.As an important mode of transportation in modern society,air transport is closely related to urban development,and the study of aviation network becomes an important perspective to analyze urban system.Based on air passenger data from Chinese 207 major airports in 2016,this paper discusses the hierarchical structure and spatial connection of the Chinese urban system from the perspective of aviation network by using ArcGIS,social network and other analytical methods.Studies have shown that from the perspective of hierarchy,the country is divided into four levels,including national central city,regional central city,sub-regional central city and local central city,and that the numbers of the cities are increasing from top to bottom with Beijing,Shanghai,Guangzhou and Chengdu as the four centers.And the national urban system forms a rhomboid network structure.In addition,by analyzing the spatial connection,the top 10 cities are mostly located in the eastern coastal areas,the spatial connection of cities across the country has obvious east-west differences,the eastern areas have the higher contact intensity,the Yangtze River delta city cluster is the center of China,and the country presents a multi-center network structure with urban agglomeration as the spatial carrier.
