%X Hydrological < p > 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 the Chinese Academy of Sciences, macro survey and dynamic research on remote sensing of resources and environment, which is based on Landsat in three years by means of satellite remote sensing MSS, TM and ETM Remote sensing data set up a 1:100000 land use image and vector database in China. The main contents include: 1:100000 land use data in China; 1:100000 land use graphic data and attribute data in China. This data is directly cut from the 1:100000 land use data of China. 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, which is stored in shape format; there are two types of data projection: WGS84 / Albers; the data coverage is new Heihe River basin boundary (lack of data from Outer Mongolia). Land use classification attributes:Level 1 type level 2 type attribute code spatial distribution locationFarmland paddy field 113 is mainly distributed in river alluvial plain, basin, river valley and SichuanCultivated land and paddy field 112 are distributed on narrow valley platform or beach in hilly Valley (with irrigation conditions)Farmland paddy field 111 is mainly distributed on narrow valley platform or beach in mountain valley (with better irrigation conditions)Cultivated land and dry land 124 are mainly distributed in mountainous areas, and the slope is generally greater than 25 degrees (belonging to steep slope hanging land), so it should be returned to forest. Cultivated land 123 is mainly distribut
