基于夜间灯光数据的武汉市建设用地扩张规律研究
Study on Wuhan Construction Land Expansion Using Night-time Light Data
摘要
Abstract
Night-time light data from 1 997 to 2012 and two points method based on statistical data were used to extract the build-up areas of the city Wuhan.Indexes including the urban land expansion,the construction land growth type,the speed of urban land expansion,the urban expansion direction and the compactness of the city boundary were used to analysis the rules of construction land expansion of Wuhan.Research shows that:the overall expansion rate of construction land is 1 52.2%;the expansion experiences the speed of"slow-fast-slow";the distribution of the city center moves to the Southeast;the compactness of the built-up area decreases first and then increases.There is a strong positive correlation between the development level,the agricultural popula-tion and the city spatial expansion.关键词
