摘　　要：[ Objective] The study aimed to discuss the anti-erosion characteristics of different soils under artificial rainfall conditions. [ Method] Through artificial rainfall experiments, the characteristics of surface runoff and sediment yield of loess, black soil, purple soil and red soil wee cont- rastively studied under the same experimental conditions. [ Resultl Under the same conditions, red soil had the best anti-erosion ability, fallowed by purple soil, black soil and loess. In practice, soil and water conservation measures should be adopted according to erosion characters of different soils. [ Conclusion] The research could provide scientific references for the establishment of soil and water conservation measures in soil erosion ar- eas of China.[ Objective] The study aimed to discuss the anti-erosion characteristics of different soils under artificial rainfall conditions.
