定量分析了植被对降雨的再分配过程和植被影响雨滴溅蚀的方式,并比较了它们在被分配前后的击溅侵蚀能量。结果表明,在降雨量达到透流(经枝叶聚集部分)临界雨量以后,雨滴终速度越大,植被减少溅蚀能量越多。此外,植被高度是所有植被特性中影响溅蚀能量贡献率最大的因子,植被越高,它所能减弱的击溅侵蚀能量越小。
Quantitative analysis of the vegetation redistribution process of rainfall and vegetation impact raindrop splash way, and compared their attack before and after the distribution of erosion energy. The results show that after the rainfall reaches the critical rainfall of through-flow (through the branches and leaves), the final velocity of the raindrop increases and the vegetation reduces the energy of splashing. In addition, the vegetation height is the factor that affects the contribution of sputter energy to all vegetation characteristics. The higher the vegetation, the less energy it can weaken the splash erosion energy.
