In order to alleviate the contradiction between people and land, improve the quality of cultivated land and the ecological environment of the land, this paper studied the sand-fixing characteristics of soft rock by indoor experiments and promoted the field. The results showed that the complementarity of the soft rock and sand in the particle size composition, the two had mixed with the composite soil to form a good particle size distribution, increased the grain roughness, and had a sandfixing

The increasing of the content of clay increased the water retention and water retention of the sand and reduced wind erosion. Based on this sand-fixing mechanism, the practical application of arsenic sand-fixing in Daji Khan Village, Yuyang District, Yulin City had been carried out by means of soil-body reconstruction project of soft rock and sand, water, road and forest supporting projects, and the control effect is remarkable.
