该数据由中国1:10万土地利用数据直接裁剪得到。中国1:10万土地利用数据是在中国科学院“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遥感数据建立了中国1:10万土地利用影像和矢量数据库。 黑河流域1:10万土地利用数据采用一个分层的土地覆盖分类系统，将全流域分为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），26个二级类；数据类型为矢量多边形，以Shape格式存储；数据投影有两种：WGS84/ALBERS；数据范围覆盖新的黑河流域边界（缺外蒙古数据）。

China's 1:100000 land use data is a remote sensing scientific and technological team of 19 research institutes affiliated to the Chinese Academy of Sciences organized in the \"Eighth Five Year Plan\" major application project of National Remote Sensing macro investigation and dynamic research of resources and environment of the Chinese Academy of Sciences. By means of satellite remote sensing, China's 1:100000 land use image and vector database has been established in three years based on LANDSAT MSS, TM and ETM Remote sensing data. The 1:100000 land use data of Heihe River Basin adopts a hierarchical land cover classification system, which divides the whole basin 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 26 second-class categories; the data type is vector polygon, stored in shape format; there are two types of data projection: WGS84 / Albers; the data range covers a new black area River basin boundary (lack of data from Outer Mongolia).
