中文摘要：

随着社会经济蓬勃发展，中国渐渐步人民航大国行列，但很多民航机场亏损的现象并没改变，导致这种现象一个不容忽视的原因就是机场的空间分布与航空运输需求的空间分布之间存在一定的偏差。文章采用空间分析和数理统计相结合的方法，分析中国机场空间发展演变的规律，表明过去50多年中国机场分布密度增大，呈分散趋势，航空网通达性越来越高，但依然存在明显的区域差异。在探讨航空客货运量的空间格局及影响客货需求生成量的基础上，定量分析决定空港空间布局的主要因素，进一步根据中国省域层面航空运输供需分析，提出中国机场未来优化布局建议.

英文摘要：

With the developoment of society and economy, China has become a main civil aviation country in the world, but many reasons in- duee 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.
