【摘要】 以1987—2017年之间南京市土地利用/覆被变化(LUCC)为研究对象,以1987、2002和2017年的3期TM遥感影像数据为基础,通过RS/GIS技术方法从定量和定性的角度分析南京市近30年来的LUCC。结果表明:近30年间南京市土地利用/覆被发生了较大的变化,存在不同土地类型之间的相互转换,主要表现在耕地面积大量减少、林地面积增加。研究表明:南京市的土地利用类型变化主要受到政策及区域规划、经济发展和城镇化进程等方面的影响。更多还原

【Abstract】 In order to study the land use and land cover change and its driving forces in Nanjing,this paper takes the land use and land cover change in Nanjing from 1987 to 2017 as the research object. Based on the TM remote sensing image data of 1987,2002,and 2017,it analyzes the land use and land cover change of Nanjing in the past 30 years from the quantitative and qualitative perspective by RS and GIS technology. The results show that the land use and land cover in Nanjing has changed greatly in the past 30 years.There are mutual conversions between different land types,which are mainly manifested in the decrease of cultivated land areas and the increase of forest land areas. Besides,policy,regional planning,economy development,industrialization and urbanization are the main driving forces of land use type change in Nanjing.更多还原
