Soil anti-shearing intensity in water erosion process of the whole country is preliminarily researched in the article by using the firsthand data obtained through field test,indoor analytic data of the physical and chemical propertiesof soil samples and reference data. The regression model of soil anti-shearing intensity is built. The dominate factors impacting on soil anti-shearing intensity in regional water erosion process are soil capacity,ratio of silt to clay,the water content and organic matter content. Soil antishearing intensity regularly changes keeping pace with the soil type,it has obvious space distribution rules in Chinese water erosion region,including horizontal and vertical distribution rules.
