Abstract: Nanzhao County, located in the mountainous southwestern region of Henan Province at the edge of Nanyang Basin, is highly prone to geological hazards. A susceptibility assessment and zoning for these hazards is significantly important to provide targeted areas for local government's efforts in disaster mitigation, prevention, and control. Based on sample data from geological hazard investigation sites and remote sensing interpretation points within Nanzhao County for 2021, this study selected 13 evaluation factors categorized into four indicator types: terrain, fundamental geology, surface cover, and hydrological environment. Three combined models were employed to model, assess, and zone the geological hazard susceptibility: Information Value(Ⅳ) + Logistic Binary Regression, Weight of Evidence (WoE) + Logistic Binary Regression, and an Ⅳ+WoE+Logistic coupled model. The accuracy of the three model sets was validated by Receiver Operating Characteristic(ROC) curves. The final analysis indicates that the comprehensive Ⅳ+WoE+Logistic coupled model achieved the highest evaluation accuracy and is therefore recommended for application.
