摘要
根据国土资源部“构建国家级土地利用和覆被变化数据库及服务体系”项目的部分研究内容 ,简要地评述了国内外最具代表性的基于遥感数据源的土地利用与覆被分类系统——美国 1∶ 2 5万土地利用与土地覆被分类系统、中国科学院土地资源分类系统 ,并与该项目研制的基于中分辨率卫星影像的国家级土地利用与覆被分类系统进行了比较 ,给出了分类代码的相互转换关系 。
Two typical land use/cover classification systems based on remotely sensed data are analyzed and appraised briefly: 1∶250000 land use and land cover classification system in USA, and land resource classification system in Chinese Academy of Sciences. According to the important project of Ministry of Land and Resources, a national scale land use/cover classification system based on mid resolution remotely sensed data was built. Then this new system was compared to the above mentioned two systems. Finally, two code conversion tables were presented for new system compared with other two systems with the aim as reference for conversion and further work.
