中国民用机场空间分布特征研究
Study on Spatial Distribution Characteristics of Civil Airports in China

机场作为航空运输重要的交通基础设施，在政府部门要求加强对民用机场的规划、建设和运营管理背景下，其空间分布特征在学术领域一直备受关注。本研究利用ArcGIS软件，对当前中国民用机场的空间分布特征进行全面探索，发现：中国大型机场主要分布在东部地区，尤其是京津冀、上海和成都等地；中型机场的分布较为分散，没有明显的聚集特征；小型机场主要分布在中部和南部地区。中国机场的空间的分布与其地区的经济发展、地理位置、交通网络等因素密切相关。未来的机场规划和建设应该充分考虑这些因素，合理布局机场。
As an important transportation infrastructure for air transportation, the spatial distribution characteristics of airports have attracted much attention in the academic field under the background that government departments require to strengthen the planning, construction and operation management of civil airports. In this study, ArcGIS software is used to comprehensively explore the spatial distribution characteristics of current civil airports in China. It is found that: China’s large airports are mainly distributed in the eastern region, especially in the Beijing-Tianjin-Hebei region, Shanghai and Chengdu. The distribution of medium-sized airports is scattered, and there is no obvious clustering feature. Small airports are mainly located in the central and southern regions. The spatial distribution of airports in China is closely related to regional economic development, geographical location, transportation network and other factors. The future airport planning and construction should take these factors into full consideration and rationally distribute the airport.
