摘　　要：在 1973～ 1997年水沙及断面资料基础上 ,从实现黄河下游减淤并促使河槽向有利方向发展的角度 ,分析总结了不同河段中水河槽横断面形态随时间和流程变化的特征 ,研究建立了河槽横断面形态指标与河段进口前期水沙系列的定量关系 ,并对维持有利河槽形态的水沙治理措施进行了初步探讨。Based on the data of flow, sediment and cross sections from 1973 to 1997, from the aspects of decreasing sediment deposit and forming favorable channel in the lower Yellow River, this paper summarized the characteristics of the middle flood channel form changing along with time and flow, founded the relation between the index of channel cross section and the average discharge and sediment concentration in the previous term, and discussed the measure to keep the favorable channel form by adjusting the proportion of water and sediment.
