The formation and evolution of landslips were closely to regional and local tectonics in the Yangtze Three Gorges Reservoir.Appearance of landslips were controlled by regional tectonic evolution and by local tectonic reform later also.The first,landslips were properly formed as a result of deformation of reverse structure controlled by thin structure.The second,fissure system and the Yangtze direction controlled the landslips formation and scale.The third,landslips appeared mostly in the compound place of structure in different times.The fourth,the formation and evolution of the landslips controlled by Neotectonic stress field are not casual,different development stages and different distribution types in time and place of landslips result from earth crust unbalance rising,sliding direction and breaking strength of landslips result from earth crust horizontal moving,and showed mainly on compound of Neotectonic stress field and superimposing gravity stress field.
