摘 要：
This paper focuses on the influence of soil and water conservation forest on slope runoff and the sand carrying capacity of surface runoff using field experiment. In this study, Robinia pseudoacacia forestland, Pinus tabulaeformis forestland, grassland and farmland on the loess plateau of western Shanxi Province were selected as research sites. The result shows that forest and grass impact on surface runoff sand carrying capacity to some degrees. The influence sequence (from strong to weak) is Pinus tabulaeformis, grass, Robinia pseudoacacia, and farmland. Based on the analysis on the relationship between surface runoff sediment concentration and flow velocity, the surface runoff sand carrying capacity in fixed flow velocity is computed. Also, the regression model of soil erosion and runoff velocity is developed by statistics method in this paper.
