通用机场体系地理空间结构形态

通用机场是通用航空活动的重要载体,研究其空间结构形态对通用航空的发展具有重要意义.利用威尔逊模型和ArcGIS的空间分析工具,从区域通用航空资源强度、通用机场综合能力及吸引力三个方面对美国西南地区通用机场体系地理空间结构进行细致探析.研究发现:通用航空资源强度东部高于西部,这与人口经济、自然资源、农林分布相一致;基于综合能力的通用机场核心-边缘状分布格局较为明显,呈现俱乐部趋同现象;基于吸引力的通用机场集聚程度高,空间分布不均匀,主要集中在大都市区、人口密集区、大都市连绵区及墨西哥湾沿岸工业区;通用机场的分布与地区市场需求表现一致,以经济和人口为依托,大都市区的通用机场航空活动量明显高于其他区域.

Study on the geographic spatial structure of general airport system

General airport is an important carrier of general aviation activities. The study of its spatial structure is of great significance to the development of general aviation. The results show that Wilson model and ArcGIS spatial analysis tools are used to analyze the geospatial structure of the general airport system in the southwest of the United States from three aspects: the strength of regional general aviation resources, the comprehensive capacity and attractiveness of general airports.It is found that the general aviation resource intensity is higher in the east than in the west, which is consistent with the distribution of natural resources in the population economy.The core-edge distribution pattern of general airport based on comprehensive capacity is more obvious, showing the phenomenon of club convergence.Based on the attraction, the general airport has a high degree of agglomeration and uneven spatial distribution, which is mainly concentrated in the densely populated areas of the metropolitan area, the metropolitan area and the gulf coast industrial area.The distribution of general airports is consistent with the performance of regional market demand. Based on economy and population, the aviation activity of general airports in metropolitan areas is significantly higher than that in other regions.
