中国1:10万土地利用数据是由中国科学院“八五”重大应用项目《全国资源环境遥感宏观调查与动态研究》组织了中国科学院所属19个研究所的遥感科技队伍，以卫星遥感为手段，在三年内基于Landsat MSS，TM和ETM遥感数据构建的。本数据采用一个分层的土地覆盖分类系统，将全国分为6个一级类（耕地、林地、草地、水域、城乡、工矿、居民用地和未利用土地），31个二级类。这是目前我国精度最高的土地利用数据产品，已经在国家土地资源调查、水文、生态研究中发挥着重要作用。

Using a hierarchical land cover classification system, this data divides the whole country into six first-class categories (cultivated land, forest land, grassland, water area, urban and rural areas, industrial and mining land, residential land and unused land), and 31 second-class categories. This is the most accurate land use data product in China, which has played an important role in the national land resource survey, hydrological and ecological research.
