从形成高浓度粗泥沙水流机理出发，综合分析了不同地层侵蚀产沙对黄河粗泥沙的影响。分析认为，风沙和基岩产沙对黄河粗泥沙均有一定影响，但起关键作用的仍然是黄土。风沙、基岩、黄土产沙的综合作用是形成黄河高浓度粗泥沙水流的重要原因，因此应从整体上综合治理多沙粗沙区。
Based on the mechanism of formation of high concentration coarse sediment flow, the influence of different formation erosion and sediment production on the coarse sediment of the Yellow River was analyzed. Analysis shows that the sandstorm and bedrock-producing sand have a certain impact on the coarse sediment of the Yellow River, but the key role is still the loess. The combined effect of sandstorm, bedrock and loess production is an important reason for the formation of high-concentration coarse sediment flows in the Yellow River. Therefore, the comprehensive management of the area of sandy sediment should be conducted comprehensively.
