| 摘 要： | 本文研究了油松和山杨林枯枝落叶层对径流速度的影响，结果表明，它与坡度、径流深度成正比，与枯枝落叶厚度成反比。枯枝落叶种类不同，其径流速度的变化规律基本一致。

| Abstract: | It is found by study on the runoff velocity in the layer of litter, that the runoff velocity was increasing with slope steepness and depth of runoff and was decreasing with increasing the thickness of litter.Even if the types of litter were diferent,the changing pattern of runoff velocity in it was about the same. |
