摘　　要：细沟侵蚀是黄土高原地区坡面土壤侵蚀的主要方式之一,在土壤剥蚀—搬运—沉积过程中具有重要作用,开展细沟侵蚀研究对于深入了解坡面土壤侵蚀机理与建立水土流失模型具有重要意义。从野外调查研究、室内模拟研究及细沟形态定量化等3个方面对坡面细沟侵蚀与特征的研究状况进行了综述,并探讨了细沟侵蚀研究的发展趋势。Rill erosion is one of the main types of soil erosion on the hill slopes of Loess Plateau and it has played an important role in the process of soil denudation,transportation and deposition. Therefore,it has great significance to study rill erosion for deep understanding the mechanism of slope soil erosion and building soil and water loss model. The paper briefly summarized the research status and the characteristics of rill erosion on the hill slopes from three aspects of field investigation,laboratory simulation and quantitative representation of rill morphology.It also discussed the development trend of the study on rill erosion.
