Although forest canopy layer could prevent splash erosion effectively, clay was taken away by overland flow and run off easily, the erosion amount became less after removing the forest canopy and surface soil, while the splash erosion still produced in the surface layer; the splash function weakened after having water current, the starting particles were less than bareland, so removing the surface disturbed soil made the erosion amount and clay less, silty sand more than bareland, but unsteady, the wear and tear energy used by raindrop splash and current function for overcoming sediments separating and starting were comparatively large, sediments were very difficult to be started and transported, it explained that forest root systems could increase anti-erosion capability of forest vegetation, make rainfall-current system splash and export finer particles than bareland.

虽然林冠层能有效防止溅蚀的发生,但坡面流还是能带走粘粒部分,粘粒还是容易流失。去除林冠和表层土后,侵蚀量变得更少,但表层还是会被溅蚀,有水流后,溅蚀作用减弱,颗粒起动的比裸地的少,所以,去除表层扰动土后,侵蚀量更少,粉沙多,粘粒比裸地更少一些,但不稳定,雨滴击溅和水流作用用于克服泥沙分离起动损耗的能量较大,很难被起动输移,这说明森林植被根系的作用增加了林地植被的抗蚀力,使降雨一水流系统仅能溅起输出比裸地坡面更细小的泥沙颗粒。
