摘　　要：近期黄河宁蒙河道增淤主要是支流高含沙洪水携带泥沙造成的,天然来水大量减少和工农业用水猛增造成河道输沙水量大减,也增加了河道淤积,龙刘两库对该河道增淤影响甚微。The sediment accumulation has been recently increased on Ningxia - Inner Mongolia reaches mainly as result of high silt - laden flood of tributaries. The reduction of a large amount of natural water and big consumption of agricultural water have not only brought a great decrease of water for sediment transport, but increased sediment accumulation of river channel. However, Longyangxia and Liujiaxia reservoirs impose minor impact on sediment accumulation of river channel.
