Abstract：The studies on root system of plant community and soil anti-scourability reveals the rule of it where in the same soil type, site condition, vegetation type and age of stand between plots. The effect of plants' root system to soil anti-scourability is analyzed. That plants' rich root system can change the character of soil is concluded. It can increase soil organic matter, aggregate content of water stability and non-capillary soil porosity, decreasing soil bulk density. Soil and soil permeability can be loosed and enhanced by the increase of organic matter, and then, soil anti-scourability can be enhanced. To control soil erosion, afforestation and forest management should be enhanced in Datong county, Qinghai province.
