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.
