Evaluation of Disaster Susceptibility and Analysis of Influencing Factors in Tuquan County

Geological disasters are complex and serious natural disasters that are related to geological conditions and affected by human activities and climate change. Therefore, it is of great significance to evaluate the susceptibility of geological disasters and analyze their main influencing factors. This study took Tuquan County, Xing'an League, Inner Mongolia Autonomous Region as the research object. Eight indicators, including elevation, terrain slope, landform type, geological structure, rock and soil type, vegetation coverage, water flow intensity index (SPI), and terrain wetness index (TWI), were selected for susceptibility evaluation. The final results were divided into four areas: high, medium, low, and non-susceptible areas. The study found that geological disasters in the region are affected by factors such as rainfall, earthquakes, and human engineering activities. Rainfall and human activities are the main triggers for the development of disasters.
