Abstract:Compared with other large reservoirs in China and abroad,the hydro-fluctuation belt of the Three Gorges Reservoir is characterized with high annual hydro-fluctuation,heavy waves caused by busy shipping in the main stream and a large area of fertilized cultivated land.After filling of a reservoir,great geo morp hologic changes should occur on the bank slope and final stable slopes has following three types:silting beach slopes,eroded bedrock slopes and eroded earth slopes.Geomorphologic evolution processes on bank slopes of the hydrofluctuation belt can be divided into three stages of severe erosion,general stable and gradual silting up.Vegetation mediation on the bank slopes should be seriously affected by soil losses during the geomorphologic evolution processes after reservoir filling.Little researches have been done on geomorphologic evolution of the bank slopes in the hydro-fluctuation belt of the Three orges Reservoir.Little attention has been paid to the geomorphologic evolution of the bank slopes in the existing key research projects on ecology and environment remediation in the hydro-fluctuation belt of the Three Gorges Reservoir.From the view of the geomorphologic evolution of the bank slopes,suggestions on research and remediation of the ecology and environment in the hydro-fluctuation belt andon adjustment of reservoir operation scheme are also proposed.
