Abstract To research the sand-fixing effects of compound soil by mixing feldspathic sandstone and sand, we monitor the soil crust thickness, depth of soil freezing, soil moisture, surface roughness, snow melt, and other related indicators by using the method of combining experimental plot and field experiment. With the introduction of the feldspathic sandstone in the compound soil, clay-silt content increased, the soil saturated hydraulic conductivity decreased, while soil moisture, crust thickness, surface roughness and frozen layer depth have increased, capacity of resist wind erosion enhanced. In the winter, through the development of conservation tillage, crop residues, root, the changes of terrain factors after land remediation, and other measures to prevent soil erosion also played a positive role.

Key words: feldspathic sandstone sand compound soil sand-fixing effects
