摘　　要：利用1951—2007年长系列的水文资料,对淮河干流鲁台子至吴家渡河段进行输沙平衡分析。结果显示,1951—2007年本段淮干累计呈淤积状态,但自50年代起10年平均淤积量逐年代递减,至80年代已由淤转冲。进一步分析了鲁台子站流量、含沙量、汛期和非汛期、行洪区启用状况等因素对泥沙输移的影响,得出了河段冲淤变化与各相关因子的关系。Based on observed data from 1951 to 2007, the sediment transport balance of Huaihe River main stream from Lutaizi to Wujiadu is analyzed. It is shown that this reach is deposited from 1951 to 2007. The amount of deposition sediment is decreased decade by decade from 1950s. 1980s is a boundary, before it the reach is deposited ; after it the reach is scoured. The influence of Lutaizi＇ s flow and sediment concentration, flood season and non-flood season and the usage of flood-storage district on sediment transport is further analyzed. The relationship between sediment deposition-scouring amount and interrelated factors is obtained.
