Geohazard Susceptibility Assessment and Prevention Strategies Driven by Integrated Geoecological Mechanisms

High ecological value mountainous counties frequently experience geological hazards, severely constraining regional sustainable development. To formulate scientifically sound prevention strategies, this study employs Pingshan County as a case study. We innovatively integrate ecological regulatory factors—including carbon storage, habitat quality, water production, and soil conservation quantity—to construct an integrated geological-ecological evaluation system. Leveraging the geodetector to quantify the explanatory power (q-values) of these factors, a weighted information value method was applied for susceptibility assessment. Bivariate spatial autocorrelation analysis was further utilized to reveal the spatial distribution patterns of hazards. The results indicate that topographic relief, slope gradient, and elevation are the core geological drivers. Geological hazard susceptibility exhibits a distinct high in the west, low in the east spatial pattern. A significant positive correlation was found between hazard risk and NDVI/habitat quality, uncovering a paradoxical phenomenon termed ecological advantages masking underlying geological risks. Based on these findings, we propose a monitoring-governance-policy tripartite prevention framework. This framework provides a theoretical tool for coordinating hazard prevention and control with sustainable development in critical ecological barrier zones
