A RESEARCH ON AIRPORTS DISTRIBUTION AND DETERMINATIVE FACTORS IN CHINA IN THE PAST OVER FIFTY YEARS:BASED ON SPATIAL ANALYSIS AND QUANTITATIVES STATISTIC
采用空间分析和定量统计方法，研究过去50多年中国机场分布规律及演变，发现分布密度提升、分散化、网络连通性增强但区域差异仍存，并基于客货空间状况提出机场布局的决定因素和未来调整方向。
With the development of society and economy,China has become a main civil aviation country in the world,but many reasons induce that income is much higher than payout in many airports.One of the main reasons is that there are deviations between the distribution of airports and demand of air transport.The paper adopts spatial analysis and quantitative statistic,analyses the distribution law of airport development and evolvement,which indicates that distribution density of airports has boosted,and distribution dispersed,connectedness of air net is higher and higher in the past 50 years,but regional discrepancy is still existent.Based on spatial situation of passengers and cargoes through air transport,the paper puts forwards the main factors that determine distribution of airports.Lastly,according to supply and demand analysis of air transport in view of provinces,the paper advances fitting direction of airports layout in China future.
