| 摘 要： | 对黄河中游河口镇至龙门区间的产沙岩层与河流悬移质输沙进行了耦合平衡分析,确定了该区间各种产沙岩层的产沙数量,并推算出黄土、基岩和风沙对河流粗泥沙(d>0.05mm)的贡献率分别为61.2%、34.2%和4.6%。同时,分析了该区间侵蚀产粗泥沙的分布规律。

| Abstract: | Based on the quasi-equilibrium theory of sediment yield, the eroded strata and suspended sediment of some branches of the Yellow River have been analysed.The results show that all eroded strata are source of sediment yielding and every stratum can cause different yield of suspended sediment in each basin, influenced by environmental factors. In details, among the total yield of coarse sediment in the rivers, there is about 61.2% from loess, 34.2% from rockstratum and 4.6% from sandland. Meanwhile, the distribution law of coarse sediment yielding is also discussed in this paper. |
