Abstract:: In view of the soil loss in the semiarid area of the western part of Heilongjiang Province, the characteristics and processes of rainfall and overflow under different tillage methods and rainfall intensity were studied based on artificial simulation of rainfall field experiment in the runoff plots on slope farmland. The experiment demonstrated that the more the rainfall intensity is, the more surface runoff and the erosion amount is, namely, the quantity of sediment was positively correlated with rainfall intensity and runoff. The order of the soil erosion under different tillage managements is as longitudinal ridge bare land>cross ridge bare land>contour planting land>subsoiling land>straw covered land>ridge direction land. The vegetation-covered land is efficient in controlling soil and water loss. The ridge direction land is better than the other tillage measures in reducing soil and water loss of slope farmland.
