Depended on the analysis of ground snow situation,soil moisture loss speed and soil structure after planting crops of Mu Us Sandy Land remedied with feldspathic sandstone in the fallow period,it is concluded that feldspathic sandstone mixed with sand improved the sand stabilization in the governance of Mu Us Sandy Land in the fallow period.The sandy land remedied with feldspathic sandstone had big snow coverage,25％-75％ higher than normal sand; soil moisture losses slowed down,and moisture content rose by over 3 times;soil structure had been improved,and water stable aggregate content increased by 6.52％-18.04％; survival rate of protection forest increased to 85％; and ground flatness is less than 1％.The above conditions weakened sand rising conditions of Mu Us Sandy Land in the fallow period and formed two protective layers of snow cover and soil frozen layer under cold weather so as to prevent against wind erosion.
