This data is directly cut from the 1:100000 land use data of China. 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).
