%X The data adopts 1km spatial resolution and WGS-84 projection mode, and the data format is grid format. The soil texture attributes and categories represent the soil texture attributes of 0-30cm in the surface layer, which are obtained by depth weighted average. Textname in the attribute table indicates the name of soil texture type; sandrange, siltrange and clayrange respectively indicate the content range of sand, silt and clay in USDA soil triangle map; Sandage, silverage and clayage are taken from the average content of sand, silt and clay in the measured soil profile as the sand, silt and clay content of the soil type. (Note: the grain content of clay loam comes from the soil quality map of Beishida). The classification standard of soil texture is USDA system in the United States. The sand size is defined as (2-0.05mm), the silt size is defined as (0.05-0.002mm) and the clay size is defined as (& lt; 0.002mm).
