摘要： 通过人工模拟降雨试验,分别观测降雨过程中不同方向上溅蚀强度的变化,根据各影响因子间相互消长及相互制约的关系特点,分析了雨滴溅蚀发生的过程特征及其变化原因.从溅蚀过程的变化特点及溅蚀强度的变化规律比较,定量地探讨了坡度对雨滴击溅侵蚀的影响作用,得出了溅蚀强度与坡度因子之间的关系方程.

Abstract: In this paper, splash erosion process and its relation to slope gradient were studied under simulated rainfall, characteristics of splash erosion process and associated reasons were analyzed through a consideration of splash erosion rate in all directions and interactions among factors affacting splash erosion. On the basis of results from regression analysis, quantitative fomula for splash erosion modeling related to slope gradient were derived.
