摘要
利用人工模拟降雨装置，对水平阶林地、梯田、坡耕地在百年一遇暴雨下的产流产沙规律进行了试验研究。研究结果表明，与陡坡耕地相比，坡耕地退耕实施水平阶整地造林后，可减少径流８７５％，减少土壤侵蚀９９７％，径流深与降雨历时之间存在着很好的对数函数关系。
The experimental study of runoff and sediment production law of forest on leveling steps, terrace and slope lands is carried out under the storm of once a hundred year by using man-made rainfall stimulating set. The results show that forest on smooth slope land with treatment of leveling steps can decrease runoff and soil erosion by 87.5% and 99.7% respectively in Comparison with that on steep slope lands, and there is perfect logarithmic function relation between runoff depth and rainfall duration.
