Research Progress on Relationship of Sediment Yield and Erosion Mechanism Between Hill Slope and Gully Slope System
【摘要】 坡沟系统侵蚀过程及其机理研究是当前土壤侵蚀过程研究的热点和难点所在。回顾了对坡沟侵蚀形态垂直分带、坡沟侵蚀产沙特征、上方来水来沙对土壤侵蚀过程的影响、坡沟侵蚀水力学机理以及坡沟侵蚀动力学机制的研究进展。分析了研究中存在的问题,提出了有待于进一步开展的研究工作。
【Abstract】 Research on hillslope-gully slope erosion process and its mechanism is the hot point and difficulty for studying soil erosion process at the present.Research progresses about vertical erosion zones of slope-gully system,erosion and sediment characteristics of hillslope-gully slope erosion,effects of up-slope runoff and sediment on down-slope erosion process as well as hydraulics mechanism and dynamics process of hillslope-gully slope system are outlined and reviewed.Furthermore,the existing problems in current research are analyzed and further research issues in the future are presented.
【Key words】 hillslope-gully slope system； erosion and sediment yield； hydraulics and dynamics； research progress；
