摘　　要：为研究重庆涪陵河段河床演变过程,本文采用重庆涪陵河段在三峡水库蓄水影响前后的河道地形和固定断面观测资料,分析了岸线、洲滩、深槽、冲淤量等变化。结果表明:三峡水库蓄水前,重庆涪陵河段总体呈冲刷态势。三峡水库蓄水后,重庆涪陵河段总体呈淤积态势,但淤积强度较小。The river prototype and fixed cross section observation data before and after the impoundment of Three Gorges Reservoir is adopted for analyzing the changes of the shoreline,shoal,deep groove,amount of scour and deposition,etc,in order to study on the river evolution of Chongqing Fuling reach. The results show that Chongqing Fuling reach has been scoured as a whole before the impoundment of TGR,however deposited after the impoundment of TGR.
