[Objective] The objective of this study is to investigate the development characteristics and mechanism of the regional geological hazards in Shuitianba area in the Xiling Gorge, and to provide the basis for preventing and controlling geological disasters in the region. [Methods] The type, size, slope structure, lithology, elevation distribution and slope gradient of geological disasters were investigated in detail, and statistical analysis was done. [Results] The major geological disasters include landslides, collapses(dangerous rock) and unstable slopes, and vary from small to medium-sizes. Spatially, regional distribution was not uniform, geological disasters more developed in elevation between 300~800 m with slope range from 20° to 40 ° and belt-like geological disasters developed along the main structure and fracture. The vast majority of geological disasters were formed in three stages: Penglaizhen formation(J₃p), Suining formation(J₃s) and Shaximiao formation(J₂s) in the lithology of Jurassic, and mostly distributed in bedding slope. The geological disasters mostly occur in flooding season from June to September. [Conclusion] The internal factors affecting the formation of the geological disasters include topography, lithology, slope structure type and geological structure while external factors include rainfall, reservoir water fluctuation and engineering activities by human beings.
