%X Taking the Minqin county as the research region, the sand soil crust sample in different geomorphic site and plant community were collected, and its physical and chemical characteristics were analyzed, in which the soil mechanical composition, soluble salt, soil nutrient elements, organic matter, Ph value, CEC and CaCO 3 content were included. The result showed that whether in the sand dune or the takyr soil, the crust soil mechanical composition is mostly composed by sand (1~0.05mm) and coarse silt partic...
