This paper focuses on the functions of soil and water conservation of forest stands with different densities in western Shanxi Province on the Loess Plateau. Using artificial raining device, Chinese pine ( Pinus tabulaeformis ) and black locust( Robinia pseudoacacia ) were selected as the research stands, and the infiltration amount, ultimate infiltration capacity, initial losses, initial abstraction duration, runoff and sediment yield were taken as indexes of soil and water conservation functions. It can be concluded that,(1)ultimate infiltration capacity is increased with the increase of the density of forest stands, but runoff and sediment yield is sharply decreased with the increase of the density; (2)the functions of soil and water conservation of forest stands are different according to the different forest densities. In the research area, the optimal density of forest stands is 3 000 trees per hm\+2.
