Abstract: Qianxi County features complex geological conditions and frequent human-induced modifications to the natural environment, resulting in significant development of geological hazards that pose serious threats to people's life and property. Based on the analysis of the geological conditions contributing to hazard development in Qianxi County, the authors selected eight assessment indicators to construct a susceptibility assessment index system, including elevation, slope gradient, slope aspect, relief amplitude, engineering geological rock groups, distance from structural features, distance from roads, and distance from rivers. The independence of these indicators was validated through correlation analysis and collinearity diagnostics. The information value (Ⅳ) method was applied to calculate the information values for each assessment indicator, and subjective and objective weights were determined using the analytic hierarchy process (AHP) and entropy evaluation method (EEM), respectively. The comprehensive weights were then derived using minimum information entropy, and three models were established, that is, Ⅳ, WIV and AHP-EEW coupling model. The susceptibility assessment results were classified into four levels (non-susceptible, low, moderate, and high) using the natural breaks method, and then validated by receiver operating characteristic (ROC) curve. The results indicated that the AHP-EEM coupling model achieved the highest accuracy, and the high, moderate, low, and non-susceptible zones covered 270.85 km² (accounting for 18.54%), 462.09 km² (accounting for 31.63%), 486.13 km² (accounting for 33.27%), and 241.93 km² (accounting for 16.56%), respectively. The AUC value of AHP-EEM coupling model was 0.875 6, demonstrating the highest alignment with the distribution of existing hazard sites and accurately reflecting regional geological conditions. The findings could provide valuable references for future disaster prevention and mitigation in this area.
