摘　　要：对青铜峡水库运用方式及排沙历史进行了回顾,计算了不同排沙方式下排沙期内水库下游河道的冲淤变化情况。结果表明:青铜峡水库排沙对下游河道的淤积影响不大,主要是在青铜峡—石嘴山河段造成短暂的淤积。According to the analysis of Qingtongxia Reservoir operation and sediment ejection history, the downstream riverbed erosion and deposition under different sediment ejection ways are calculated. The results show that the main effect on downstream river is the short-term siltation between Qingtongxia and Shizuishan section. Overall, sediment ejection has little effect on the downstream river siltation.
