## 5 Conclusions  
Geological disasters occur frequently in the study area, among which the main inducing factor of landslides is rainfall. According to the results of geological survey and statistical analysis, the formation of landslides caused by rainfall is mainly manifested in two aspects: first, continuous heavy rainfall saturates the slope and reduces the physical and mechanical properties; second, slope foot ditch erosion caused by rainfall. There is a strong distribution law along the river valley in the spatial distribution, and it is related to the rainfall height in the temporal distribution. Based on the analysis and evaluation of extreme precipitation trends in the study area, the vulnerability of the study area was evaluated by using the informational quantity model (AUC (area under the curve) = 0.81). The proportion of the areas with high incidence, medium incidence and low incidence in the study area was 6.51%, 27.96% and 65.53%, respectively.  
The analysis of susceptibility evaluation results shows that the high-susceptibility areas of geological disasters in the study area are mainly distributed on both sides of the main stream of the Jinshajiang River and the first-level tributaries, and concentrated urban development areas. The areas along both sides of the main stream of the Jinshajiang River are mostly the medium-prone area except for the high-prone area. Most of the Baihetan Hydropower Station Reservoir Area, Xiluoudu Reservoir Area and Xiangjiaba ReservoirArea are in the high- to medium-prone area to geological disasters, while the Wudongde Reservoir area is in the medium- to low-prone area to geological disasters.  
The results of the susceptibility assessment and the distribution of hazard sites are a good fit. The high-susceptibility areas are mostly located in areas with strong topographic cuts. At the same time, there are more human activities such as road construction, residential land, and construction of industrial facilities. The topography is the main controlling factor for the occurrence of geological hazards, and human engineering activities and rainfall are the main triggering factors. Geographic information system (GIS) has strong spatial expression abilities and spatial analysis abilities. It can analyze the quantitative relationship between geographical phenomena and their influencing factors through GIS, and is widely used in geological hazard vulnerability assessment, environmental impact assessment, mineral potential assessment, etc. [41; 42]. The spatial analysis function of ArcGIS is used to study the factors affecting the risk of geological hazards under extreme rainfall trends and to derive the risk zones through superposition analysis. The study will provide a reference basis for the planning of geological hazard prevention and control by formulating targeted mitigation strategies and geological hazard risk management measures to adapt to climate change in the Yangtze River Basin.
