| Under the dual promotion of market demand and national policy guidance,China’s general aviation industry is forming the concept of industry development driven by service leading terminal,and has gradually become a key industry to cultivate new economic growth drivers and one of the main development directions of strategic emerging industries.General airport is an important carrier of general aviation activities.With the introduction of relevant policies,the construction of general airports in China is gradually developing towards specialization and standardization.However,at present,China’s general airports are still in a growth period,and there is still a large gap between the construction scale of airports and the national economic industry.In order to realize the leapfrog development of general airports,a clear layout planning is needed.It is of great significance for the development of general aviation to make full use of resources to optimize the general airport layout structure and to construct a perfect general airport development framework and space structure form.Based on spatial structure theory and spatial interaction theory,this paper studies the strength of general aviation resources and the comprehensive service capability of general airport within the service scope of general airport,aiming at summarizing the mature and perfect spatial pattern of general airport system.This article first consults relevant materials and summarizes the theories and methods related to the general airport spatial layout in domestic and foreign literature,organizes the ideas of the paper,and focuses on the innovation of the paper;Then it briefly summarizes the basic meaning of space structure and form,the theory and application of space structure,the theory of space-related effects and the method of space analysis,which will lay a solid theoretical foundation for the analysis of the space structure form of general airport system in the next step;Then it summarizes and analyzes the factors that form the spatial structure of the general airport system,briefly introduces several mature general airport layout patterns that have been formed abroad,and analyzes the general airport layout factors and spatial distribution effects in detail;Then,the Wilson model,the spatial interaction model required by the thesis,is introduced,combined with the actual situation of the general airport,the Wilson model is improved,and the average nearest neighbor index is added,and the distance between airports is used as a competition factor to construct a general airport comprehensive capability evaluation index system.Estimate the comprehensive service capacity of the airport,use the spatial analysis tools of Arc GIS software to process the data,and elaborate the geospatial structure of the general airport system in the southwestern United States from the three aspects of regional general aviation resource intensity,general airport comprehensive capacity and general airport spatial attractiveness.Analyze and summarize the spatial layout model of the mature general airport system.Finally,it draws suggestions and ideas for the spatial layout of my country’s general airport system.Through the research of this article,we hope to provide reference for the layout planning of general airports in our country. |
