地形决定着地面物质与能量的形成和再分配,是影响水土流失的重要因子之一。在坡面土壤侵蚀产沙研究过程中,以往围绕坡度、坡长等宏观地形因子研究的较多,而忽略了对坡面细沟侵蚀形态等微观地形因子的定量研究。系统介绍了前人在坡面细沟形态与侵蚀产沙量化响应研究中所取得的有代表性的成果,阐述了坡面侵蚀形态对坡面侵蚀产沙的影响,指出了目前细沟侵蚀研究中存在的问题和今后研究的发展方向。
Topography determines the formation and redistribution of surface matter and energy, and is one of the important factors that affect soil and water loss. In the process of soil erosion and sediment production on the slope, there are many macroscopic topographic factors around the slope and slope length in the past, while neglecting the quantitative study on the microscopic topographic factors such as the erosion morphology of the rill. This paper systematically introduces the predecessors’ representative achievements in the study of the quantitative response of sediment yield and sediment yield on the slope, and expounds the influence of slope erosion on slope erosion and sediment yield. In the existing problems and future research direction.
