摘　　要：分析了2000—2008年黄河河南段的来水来沙情况及河道断面变化情况,结果表明:①扣除涵闸引沙0.999亿t,孙口以上河段2000—2008年共冲刷泥沙8.718亿t;②除花园口—夹河滩河段河道展宽和下切同时存在外,其余河段均以下切为主;③黄河河南段2000—2008年同流量水位下降0.80～1.77 m,2003年后花园口站控制流量逐渐加大,2008年的最大流量为4 610 m3/s。The paper analyzed the incoming water and sediment and the changes of river cross-section in the Henan reach of the Yellow River from 2000 to 2008.The results show that a） deduction of the 99.9 million t of sand diverted by culvert and sluice,871.8 million t of sand are sluiced by the sections above Sunkou Station from 2000 to 2008;b） except both widening and undercutting existed in Huayuankou-Jiahetan section,in the other river sections there are only undercutting and;c） the water level with the same flow discharge in the Henan reach of the Yellow River reduced by 0.80-1.77 m from 2000 to 2008.Dominant discharge gradually increases at Huayuankou Station since 2003 and the maximum flow discharge is 4 610 m3/s in 2008.
