Abstract：The complex geological structure in Zhangjiajie City has led to its unique landform landscape, meanwhice it has also posed numerous geological hazard risks. By analyzing detailed geological hazard investigation data of Yongding District from 2014 to 2022, the authors in this paper have studied its developmental patterns and susceptibility of geological hazards. The results indicate that landslide is the primary type of geological hazard in the area. Geological hazards are spatially most prevalent in the central fault zone and the northeastern shale formation zone, and they are temporally relatively concentrated during the rainy season in May, June and July. Geological hazards in this area are closely related to landform characteristics, lithology, and tectonic activities, and they are also influenced by rainfall and human engineering activities. The density of hazard points is highest in the debris hill landform, and the susceptibility of hazard points is highest in Silurian sandy shale formation. Besides, the geological hazards are significantly influenced by tectonics, with hazard points densely concentrated in fold and thrust structures. The high incidence period of hazards is coupled with the rainy season, and the main triggering factor is rainfall. And the unreasonable engineering activities, such as slope cutting for houses and roads construction, exacerbate the occurrence of geological hazards. By using the susceptibility index method and based on ArcGIS information statistics analysis, the authors in this paper have divided the susceptibility of geological hazards in the entire area into high, moderate, and low susceptibility zones. This study could provide guidance for land spatial planning, geological hazard prevention and control, and planning for tourism routes and major engineering construction in Yongding District.
