| 摘 要： | 对黄河中游区水沙序列进行了分阶段季节统计分析，对比研究了２０多个流域的雨～水－沙关系，计算了各阶段水沙衰减量以及由于雨水衰减影响和水土保持工作影响的减沙量所占比重，对比分析了不同流域水沙变化状况，结果表明，８０年代以来，绝大多数站年输沙量大幅度衰减，主要是水土保持（包括水利工程措施）发挥了作用。

| Abstract: | In this paper,the water and sediment series at the middle reaches of the Yellow River are statistically analysed according to the stage and season._The relationships between rainfall,water and sediment for more than 20 basins are compared and researched. The sediment descending proportions caused by the reduction of rainfall and soil conservancy are respectively evaluated. The conditions of water and sediment variation at different basins are analysed. |

| Keywords: | water and sediment series sediment discharge time and space distribution descent the middle reaches of the Yellow River |
