| 摘 要： | 运用一维泥沙数学模型，对小浪底水库运行后黄河下游河道泥沙冲淤,春中着重分析艾山－利津河段的冲淤变化规律，作者认为小浪底水库可使黄河下游总体上保持20年不淤，50年内相对减淤率为51．6％，艾山－利津河段也有减淤效果，但相对减淤率仅为全下游平均值的57％，河床抬升速度仍然较快。 |

| Abstract: | Based on the one dimensional sediment mathematical model,sediment scour and silting in the lower Yellow River after Xiaolangdi reservoir operation are researched;therein the change law of scour and silting in the river reach of Aishan to Lijin is analyzed emphatically.The author recognizes that the Xiaolangdi reservoir may keep the lower Yellow River silt stable as a whole for twenty years.And,in the fifty years the rate of sediment silt would be reduced 51 6%.On the river reach of Aishan to Lijin,sediment silting may also be reduced,but the relative rate of reduction would be 57% of that the whole lower river reach only.The lifting velocity of the riverbed of this river reach would be comparatively fast. |
