摘要
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。
Topographic factor determines the formation and re-distribution of ground substance and energy. It is one of the important factors affecting the soil and water loss. In the research process of slope soil erosion and sediment production,it usually studies on the macro-topographic factors of slope gradient and slope length,but ignores the quantitative study of micro-topographical factors of slope rill erosion morphology.The paper systematically introduced the representative achievements of predecessors in the study on quantitative response of slope rill morphology and erosion sediment production,elaborated the influence of slope erosion morphology to the slope erosion sediment production and pointed out the existing problems in the present study of rill erosion and the development orientation of future research.
