摘　　要：随着经济的发展,社会需求的不断提高,不透水面面积越来越代表着社会的城市化进程和经济发展水平。为了解安徽省不透水面面积和经济发展水平,本文以安徽省为研究对象,将2018年的哨兵2号(Sentinel-2)和美国陆地卫星(Landsat8)影像相结合,利用珞珈一号夜间灯光数据为辅助数据,制作安徽省森林、农田、不透水面、水体四类地物的土地利用规划图,高精度提取了2018年安徽省全省的不透水面信息。研究结果表明:通过与Sentinel-2&珞珈一号和Landsat8&珞珈一号的结果进行对比,充分证明Sentinel-2、Landsat8以及珞珈一号数据结合能够较准确、高精度地提取不透水面信息。With the development of the economy and the continuous improvement of social demand,the impervious area is more and more representative of the urbanization process and economic development level of the society.To accurately understand the impervious surface and economic development level of Anhui Province,this study selected the training samples of Anhui province,trains the classifier,uses the classification algorithm of support vector machine,combined 2018 Sentinel-2 and Landsat8,and used the No.1 nighttime light data as auxiliary.The data was used to make land use planning maps for forests,farmland,impervious surfaces and water bodies in Anhui Province,and then the impervious information of the province in Anhui Province was extracted with high precision in 2018.Compared with the results of Sentinel-2 and Landsat8,it was proved that the combination of Sentinel-2,Landsat8 and Chang's No.1 data can extract impervious information with high accuracy and high precision.
