分析了油松人工林各部分的水土保持作用,及根系层的渗透和不同处理林地的产流产沙量。结果表明,林冠层和枯枝落叶层的截留率分别为19.76％和9.3％;枯枝落叶层阻延径流流出时间与其厚度呈正比例关系,且给出了与其被影响因子之间的回归方程。
The effects of soil and water conservation on soil and water conservation in Pinus tabulaeformis plantation and infiltration of root system and runoff and sediment yield in different treatments were analyzed. The results showed that the interception rates of canopy layer and litter layer were 19.76% and 9.3%, respectively. The litter flow outflow time and its thickness were directly proportional to each other, and the regression equation with the affected factors was given.
