分析了1986年11月-2010年10月黄河宁夏河段水沙变化及冲淤特性，并采用模型计算和实测资料分析预测了2011-2020年的冲淤情况。结果表明：1986-2010年宁夏河段多年平均来水量为250.5亿 m3、来沙量为0.67亿 t，分别为天然状态1950-1968年来水量的74.8%、来沙量的34.0%；冲淤量预测值为797万 m3，平均淤积厚度为0.013 m。

It analyzed the water and sediment variation and characteristics of scouring and deposition from the year of 1986 to 2010 in Ningxia reach of the Yellow River and predicted the volume of scouring and sedimentation from the year of 2011 to 2020 by using a numerical model and the ob-served data. The results show that the annual average water volume is 250. 5 í 108 m3 and sediment is 0. 67 í 108 t. The water volume is 74. 8% of the natural state from the year of 1950 to 1968. As to the sediment,itˊs 34. 0% of the observed data;the predicted volume of scouring and sedimen-tation is 0. 079 7 í 108 m3 ,and the average thickness of sediment on the riverbed is 0. 013 m.
