%X The data set is the HWSD soil texture data set of the Qinghai Lake basin, which is derived from the Harmonized World Soil Database (HWSD) built by the Food and Agriculture Organization of the United Nations (FAO) and the Vienna International Institute of Applied Systems Analysis(IIASA). The database released version 1.1 on March 26, 2009. The data resolution is 1km. The main soil classification system used is FAO-90The main fields of the soil attribute table include:SU_ SYM90 (soil name in the FAO 90 soil classification system)SU_SYM85 (FAO85 classification)T_TEXTURE (Top soil texture)DRAINAGE (19.5)ROOTS: String (depth classification of obstacles to the bottom of the soil)SWR: String (soil moisture content characteristics)ADD_PROP: Real (specific Soil type in the soil unit related to agricultural use)T_GRAVEL: Real (volume percentage of crushed stone); T_SAND: Real (sand content)T_SILT: Real (silt content)T_CLAY: Real (clay content)T_USDA_TEX: Real (USDA Soil Texture Classification)T_REF_BULK: Real (soil bulk density)T_OC: Real (organic carbon content)T_PH_H2O: Real (pH)T_CEC_CLAY: Real (cation exchange capacity of cohesive layer soil)T_CEC_SOIL: Real (Cation exchange capacity of soil)T_BS: Real (basic saturation)T_TEB: Real (exchangeable base)T_CACO3: Real (carbonate or lime content)T_CASO4: Real (sulfate content)T_ESP: Real (exchangeable sodium salt)T_ECE: Real (conductivity)This data can provide model input parameters for Earth system modelers, and the agricultural perspective can be used to study ecological agricultural zoning, food security, and climate change.
