摘要
降雨强度、雨滴速度、雨滴与坡面撞击角度等参量与土壤侵蚀有密切关系.其侵蚀力的大小是衡量水土流失量的关键指标之一.目前侵蚀力计算忽略了受风力影响雨滴与坡面撞击角度的影响,而导致侵蚀力计算中有较大误差.通过加入雨滴与坡面撞击角度等参数使侵蚀力计算公式优化和完善.
Many parameters such as the intensity of rainfall, the speed of raindrops and the angle from which the raindrops hit a slope are closely connected with soil erosion. The intensity of this erosion is one of the most crucial criteria of soil erosion. Most present methods to calculate erosion ignore the angle between raindrops and the slope. So there is a great error in calculation. In this thesis, the author takes it into consideration and the formula of calculating soil erosion is optimized thereby.
