Abstract:: In order to solve the problem of severe soil erosion and low use efficiency of water and soil resources, based on the collected rainfall data and field soil erosion monitoring in terraces with water and sediment regulation measures in Ansai County, north Shannxi Province, we analyzed the anti-erosion effect and mechanism of soil erosion in terraces with water and sediment regulation measures in the process of resisting the rainstorm disaster. The results showed that the terraces had the ability to resist rainstorm erosion with the degree of all the levels of terraces with middle erosion, and the average soil erosion modulus was one-seventh of annual mean value. Concentrated and high intensive rain played an important role in contributing to soil erosion modulus. Based on the corrected soil erosion forecasting model that is fit for the terraces in this region, when I₃₀ is 0.24 mm/min, soil can maintain high productivity if annual precipitation is less than 191.1 mm,and soil erosion modulus can be controlled within annual mean value if annual precipitation is less than 997.13 mm. The comprehensive effects of cellar constructed in the terrace,planting grass on the side slope of terrace,the litter mulch on the terrace and terrace quality played the important role in resisting the rainstorm-induced disaster in the terrace.
