摘　　要：引黄对鲁北工农业及社会带来效益的同时,带来泥沙淤积等生态问题,在分析内河泥沙特征的同时,计算出1970～2000年进入鲁北内河的泥沙量为1.531亿m3,年均494万m3;全面分析了引黄尾沙对鲁北平原内河的影响,认为引黄尾沙是鲁北内河主要泥沙来源,不但使内河实测泥沙资料代表性发生变化,而且加剧了内河淤积,改变了断面形状和河流形态,对鲁北内河水生态环境的健康与稳定造成了一定的影响。This paper analyzed the sediment characteristics of the rivers in Lubei Plain, and calculated that the sediment from the Yellow River into the rivers in Lubei Plain was 0.1531 billion ms from 1970 to 2000. The sediment from the Yellow River is the main source of the suspended sediment in the rivers in Lubei Plain. The sediment has not only changed the representativeness of the observed sediment data, but also aggravated sediment deposit in the rivers, which has resulted in a bad inluence on the health and stabilization of aquatic ecosystems of the rivers in Lubei Plain.
