Abstract:: The exposed feldspathic sandstone region is one of the areas susceptible to most severe soil and water losses in the Loess Plateau. Studying the effects of artificial vegetation on runoff and sediment reduction in exposed feldspathic sandstone region under natural rainfall has great significance to improve the effectiveness and quality of soil erosion control. In this research, through hierarchical clustering method and linear regression method, we divided the types of rainfall and studied their effects on soil erosion, and also analyzed the erodibility under different typies of artificial vegetation in Baojiagou watershed of Feldspathic sandstone region. The results showed that:(1)the natural rainfall types in exposed feldspathic sandstone region could be conceptually divided into four categories: long-duration heavy rain, long-duration moderate to heavy rain, short-duration heavy rain, short-duration light to moderate rain;(2)multiple linear function relation could describe the relation between P, I_30, I₁₀ of rainfall and runoff yield, sediment yield under differernt artificial vegetation types(y=ax₁+bx₂+cx₃+d);(3)the runoff reduction ability of different vegetation types followed the order: Hippophae rhamnoides>Pinus tabuliformis>Prunus armeniaca>Caragana korshinskii>grass land;(3)it was also found that sediment reduction capacity decreased in the order: Hippophae rhamnoides>Prunus armeniaca>Pinus tabuliformis>Caragana korshinskii>grass land. Construction of artificial vegetation can effectively prevent and control soil and water loss on the slope of exposed feldspathic sandstone area. Among the existing artificial vegetation types, Hippophae rhamnoides forest has the strongest ability to control erosion.
