摘　　要：本文从１９７３～１９９０年，共选取１０６个洪峰时段。分析了洪水期，三门峡出库不同含沙量级中，输沙用水量与黄河下游河道泥沙冲淤调整的关系。所得成果对三门峡水库今后的运用，以及下游河道减淤均有参考价值。Based on the field data of 106 events of various floods in the period of 1973-1990, a relationship between the water volume required for transporting 1 t of sediment load and the amount of aggradation/degradation in the Lower Yellow River for various sediment concentrations released from the Sanmenxia Reservoir in flood periods is obtained. It can be applied to the operation of Sanmenxia Reservoir to decrease the aggradation in the Lower Yellow River.

关 键 词：洪峰流量 输沙用水量 减淤 河道泥沙 冲淤
