摘要
只有弄清暴雨侵蚀产沙的作用机制,才能科学有效地进行流域水土保持治理。人工模拟降雨试验是研究黄土坡面侵蚀的重要手段。本文总结整理了大量的人工模拟试验资料,总结分析了侵蚀方式、表土结皮、坡度、上方水沙条件、降雨量、雨强、坡长等因素对黄土坡面侵蚀产沙的影响,并提出其中存在的问题和今后研究的方向。
Soil and water conservation management can be carried out scientifically and effectively when the mechanism of rainstorm erosion and sedimentation yield are clear. Hence, it is important to study the loess slope erosion by artificial simulative experiments. The researches were summarized in this paper; the effects of erosion mode, encrustation, slope gradient, runoff and sediment from upslope, rainfall, rainfall intensity and slope length on the loess slope erosion and sediment generation were analyzed; and the problems and further issues were also presented.
