| 摘 要： | 本文利用系统、 颗粒级配资料，详细分析了黄河中游主要控制站长时期泥沙组成和泥沙粒径的变化，认为近期黄河中游有来沙细化的现象，但这是由于来沙量的减少造成的，泥沙组成规律并未发生明显的趋势性变化。

| Abstract: | With the systematic and conformable data of the sediment gradation, detailed analyses are made for the long term sediment composition and variation of the sediment gradation through the main stations on the main stem of the Middle Yellow River. Results show that the phenomenon that the particles have gradually became fine in the past years is caused by the decreasing of the total incoming sediment load. Meanwhile, the law of the sediment composition remains as usual. |
