AB  - The data includes the basic terrain data, soil data, meteorological data, land use / land cover data and so on. All maps and related point coordinates (weather station, hydrological station) adopt Gauss Kruger projection coordinate system which is consistent with the basic topographic map of our country. The data content includes:b) Soil data: including soil physics, soil chemistry and spatial distribution of soil types. The scale of digital soil map is 1:1 million, which is converted to ESRI grid format, and the grid size is 50 * 50m. Each soil profile can be divided into up to 10 layers. The sampling indexes of soil texture required by the model adopted American Standard. The parameters are from the second national soil survey data and related literature. c) Meteorological data:(1) Temperature: the data of daily maximum temperature, daily minimum temperature, wind speed and relative humidity are from the daily observation data of Qilian, Shandan, Tuole, yeniugou and Zhangye meteorological stations in and around the basin, covering the period from 1999 to 2001. (2)  Precipitation: the precipitation data come from the daily precipitation data of five hydrological stations in the basin and its surrounding areas, including OBO (1990-1996), Sunan (1990-2000), Qilian (1990-2000), Yingluoxia (1990-2000), zamashke (1990-2000), and four meteorological stations in Shandan (1999-2001), tole (1999-2001), yeniugou (1999-2001), Zhangye (1999-2001), Qilian county (1999-2001) Observation data. (3) Wind speed and relative humidity: the wind speed and relative humidity come from the daily observation data of 5 meteorological stations in Shandan, Tuole, yeniugou, Zhangye and Qilian counties. The period is from 1999 to 2001. (4) Solar radiation: there is no corresponding observation data of solar radiation, which is generated by model simulation. d) Land use / land cover: 1995 land use data, scale 1:100000. It is converted to ESRI grid format, and the grid size is 50 * 50m.
