降雨动能对溶质径流过程有明显影响。本文在室内时空分布均一条件下，通过调整降雨器高度的方式改变降雨动能，由降雨径流实验具体说明了降雨动能对表层土壤水分运动、坡面漫流过程以及对泥沙和土壤溶质向地表径流迁移的影响。并初步探讨了降雨动能影响的模拟途径。
Rainfall kinetic energy has a significant effect on solute runoff. Under the condition of uniform indoor and outdoor time distribution, the kinetic energy of rainfall is changed by adjusting the height of the raindrop. The rainfall-runoff experiment illustrates the effects of rainfall kinetic energy on surface soil moisture movement, surface runoff and sediment and soil solute transport to surface runoff Impact. The simulation method of the influence of rainfall kinetic energy is also discussed.
