In this experiment, simulated rainfall and evaporation methods were applied respectively to study the effect of forest litter on surface runoff, rainfall interception and water evaporation in different L and F composition under 11 different species. The results show that: ①for the role of water source conservation, the litter layer of L 2 cm+F 3 cm was the best, the second was the layer of F 3 cm; ② Among different tree species, Larix princips rupprechtii was the best, the second were Pinus tabulaeformis and Platycladus orientalis, the other eight broad leaf tree species were the third; ③The water evaporation course in the surface litter after moisture absorption can be illustrated with index function; ④The rainfall interception under middle rainfall amount were the largest.
