AB  - The data set is the hwsd soil texture data set in the Northern Piedmont of Tianshan Mountain. The data comes from the harmonized world soil database (hwsd) built by FAO and IIASA, which was released on March 26, 2009. The data resolution is 1km. The main soil classification system is fao-90. The main fields of soil attribute table include:Su Yu sym90 (soil name in FAO 90 soil classification system)Su Yu sym85 (fao85 classification)T_texture (top soil texture)DRAINAGE(19.5)；Roads: string (depth classification of obstacles to the bottom of soil)SWR: string (soil moisture content characteristics)Add_prop: real (specific soil type in 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: realT_oc: real (organic carbon content)T? PH? H2O: realT ﹣ CEC ﹣ clay: realT ﹣ CEC ﹣ soil: realT_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. The attribute field beginning with t_represents the upper soil attribute (0-30cm), and the attribute field beginning with s_represents the lower soil attribute (30-100cm) (FAO 2009). The data can provide input parameters for the earth system modelers, and the agricultural perspective can be used to study the ecological agriculture zoning, food security and climate change.
