摘　　要：黄河中游多沙粗沙区是黄河泥沙的主要来源地,也是黄土高原土壤侵蚀最为强烈的地区。淤地坝拦截的泥沙赋存了大量侵蚀产沙信息,提供了对缺乏资料地区土壤侵蚀研究的可能。选取黄河中游的窟野河流域为研究对象,对淤地坝沉积特性进行分析,研究坝控流域的侵蚀产沙强度及泥沙来源,模拟流域不同时期土壤侵蚀情况。结果表明,流域产沙模数与降雨量显著相关,年产沙量呈下降趋势,主要泥沙来源为裸地。More rough sandy area in the middle of the Yellow River is the main source of the Yellow River sediment,and it is also the area where the soil erosion of the Loess Plateau is the strongest.The sediment intercepted by the silt dams retains a large amount of erosion information,which provides the possibility to study soil erosion in areas lacking data.In this study,the cave wild river basin in the middle of the Yellow River was selected as the research object to analyze the characteristics of the silt dam deposits,study the erosion of sand production and sand source of the dam-control basin,and simulate soil erosion in different periods of the basin.The results showed that there is a significant correlation between sediment yield modulus and rainfall,showing a decreasing trend and the main source of sand is nudation.
