摘　　要：根据实测资料,分析了小浪底水库初期运用(2000-2006年)期间水库淤积的特点,重点研究了水库运用对下游来水来沙条件的改变、下游河道冲刷及其特点、水库与河道泥沙冲淤的关系等等,并与三门峡水库蓄水拦沙运用期间下游河道的变化进行了对比,据此对小浪底水库运用及调水调沙提出了建议。Based on the lower Yellow Riv Xiaolangdi Reservoir the measured data, the sedimentation characteristics in Xiaolangdi Reservoir and responses of er during the initial operation from 2000 to 2006 have been analyzed, including the effect of operation on the flow and sediment condition entering the lower Yellow River, the erosion characteristics of the lower Yellow River, and the relation between reservoir sedimentation and downstream channel erosion. These characteristics are then compaired with those by Sanmenxia Reservoir during its initial operation from 1960 to 1964. Finally, some suggestions to Xiaolangdi Reservoir operation and flow-sediment regulation are proposed.
