摘　　要：淤地坝作为重要的水土保持工程措施,在减少入河泥沙方面发挥重要作用。通过直接拦截滞留流域侵蚀泥沙,淤地坝泥沙赋存大量流域土壤侵蚀信息,庞大的淤地坝样本量以及悠久的淤地坝建设历史与淤地坝沉积泥沙旋回的发现与断代技术的不断完善为利用淤地坝泥沙研究流域侵蚀特征、侵蚀机理以及流域环境演变提供主要途径。通过查阅国内外淤地坝研究文献,归纳总结了基于淤地坝泥沙解译流域侵蚀速率、判别淤地坝泥沙来源以及反演流域侵蚀环境变化等侵蚀信息的相关研究,分析现阶段基于淤地坝沉积泥沙解译小流域侵蚀信息研究中存在的问题并探讨了今后研究发展的方向,以期能为进一步挖掘淤地坝泥沙赋存的土壤侵蚀信息提供参考。Check dam is one of the most important engineering measures for controlling soil and water loss from watersheds and can play a key role in reducing sediment loads in rivers.In addition,based on the sediment sources of check dams,a large sample size of check dams,a long history of check dams,the visible flooding episodes in check dams and constantly improved dating techniques of sediment deposits,and the asso ciated sediment deposits of check dam can provide valuable sources of information on changing rates of sediment production from the upstream of watershed through time and a new way to study soil erosion characteristics,erosion environmental evolution and erosive regularity.Studies on using sediment in check dam to interpret soil erosion rate,sediment sources and erosion environment information are summarized through literature review.The future focuses on sediment in check dam are pointed out by analysis the problems to provide references for future study on using sediment in check dam to interpret soil erosion information.
