摘要
浅沟是黄土丘陵沟壑区的重要产沙方式之一,是在径流冲刷和人类耕作共同作用下形成的。介绍了浅沟侵蚀发生发展过程、浅沟水流水力学特性、浅沟侵蚀影响因素、浅沟侵蚀预报模型等进展,提出了今后亟待加强的研究领域,包括浅沟发生的临界动力条件、浅沟发育过程的定量描述、浅沟水流的剥离方程及泥沙搬运能力、动态监测浅沟侵蚀过程的新方法、包括浅沟侵蚀的坡面土壤流失预报模型等。
Ephemeral gully is one of the important soil erosion patterns at hilly-gully region of the Loess Plateau.Its initiation and development is closely related to runoff scouring and human farming.The authors outlined ephemeral gully process,hydraulic characteristics of ephemeral gully flow,affecting factors and prediction models of ephemeral gully erosion.Strengthening research fields of ephemeral gully erosion are proposed,including critically dynamic parameters,qualifying ephemeral gully erosion process,detachment equation by shallow gully flow,transport capacity of shallow gully flow,soil loss predicting model related shallow gully and new methods for monitoring shallow gully process.
