摘　　要：根据黄河中游多沙粗沙区的地貌特征及降雨特性，以窟野河上游乌兰木伦河流域为研究对象，提出了考虑降雨时空分布不均的流域产流模型，建立了次暴雨径流产沙概念模型，经实测资料检验精度良好。该模型可用于较精确的估算多沙粗沙区次降雨条件下的流域产沙量及其在时程上的变化，对黄河中游水土保持治理规划。Based on the characteristics of landform and rainfall in the heavy erosion and coarse sedimental region in the middle reaches of the yellow River, this paper takes the upper reaches of kayche,wulanmulun watershed as the research object, a watershed runoff model which takes the uneven distribution of rainfall into consideration has been esteblished using the runoff and collection flow model, the discharge and sediment yield model of mediunm watershed single rainfall event has been esteblished. The results are excellent examed by the observed information. The model can be applied to estimate accunitely the sedimetn yield of single rainfall event for the heavy erosion and coarse seclimental region and the charge of sediment discharge process in time and distance.
