摘要
利用1986、1996、2002年同时期的遥感图像数据和地形图,在ArcG IS及其他相关软件的支持下,获得南京市土地利用的现状、动态变化等类专题图。在对土地利用类型变化的幅度和土地利用类型之间转换的时空关系进行了研究后,结果表明:1986-1996-2002年,南京的土地利用变化总趋势是耕地面积迅速减少,林地和水域用地变化不大,开发建设及居住用地迅速增加,唯有重要生态功能的湿地等类型面积急剧减少。城市化进程及工业发展是土地利用发生时空变化的主要原因。
Using the remote sensing data of 1986, 1996, 2002 and topographic map, actual and dynamic changes land use map of Nanjing was obtained based on ArcGIS and other software system. The study on spatial relationship between change extent and change of land use type showed that from 1986 to 1996 and 2002, there was a great change of land use in Nanjing. The area of arable land decreased rapidly, forest and water land changed a little, development land and resident land increased rapidly, wetland and other kind of land with important ecology function decreased a lot. Study showed that the citification and industry development was the main reason of spatial - temporal changes of Nanjing land use/cover.
