Landuse/landcover dataset of the Heihe river basin (1980s)

The data was directly clipped from China's 1:100,000 land-use data.China 1:100000 data of land use is a major application in the Chinese Academy of Sciences "five-year" project "the national resources and environment remote sensing macroscopic investigation and study of dynamic organized 19 Chinese Academy of Sciences institute of remote sensing science and technology team, by means of satellite remote sensing, in three years based on Landsat MSS, TM and ETM remote sensing data established China 1:100000 images and vector of land use database.A hierarchical land cover classification system was adopted for the land use data of heihe basin of 1:100,000, and the whole basin was divided into 6 primary categories (arable land, forest land, grassland, water area, urban and rural areas, industrial and mining areas, residential land and unused land) and 26 secondary categories.The data type is vector polygon, which is stored in Shape format.There are two types of data projection: WGS84/ALBERS;Data coverage covers the new heihe watershed boundary (lack of outer Mongolia data).

该数据集直接截取自中国1:100,000土地利用数据。中国1:100,000土地利用数据是中国科学院‘五年’项目‘国家资源与环境遥感宏观调查与研究’的重要应用之一。该项目由中国科学院遥感与数字地球研究所团队承担，历时三年，基于Landsat MSS、TM和ETM遥感数据，建立了中国1:100,000的土地利用影像和矢量数据库。对于黑河盆地的土地利用数据，采用了分层土地覆盖分类系统，将整个流域划分为六个一级类别（耕地、林地、草地、水域、城乡区域、工业与矿业区域、住宅用地及未利用地）和二十六个二级类别。数据类型为矢量多边形，存储于Shape格式中。数据投影类型包括WGS84/ALBERS；数据覆盖范围包括新的黑河流域边界（缺少 Outer Mongolia 数据）。
