Description
Yang Wen and colleagues build a combined model for geological hazard risk at county scale in a 2026 case study of Ningyuan County in Hunan Province, China. Landslides and related disasters threaten lives and property, but traditional risk scoring leans on subjective expert weights and misses how factors interact. The team coupled a random forest model with an extreme rainfall assumption method and an analytic hierarchy process.
The susceptibility model scored an accuracy measure of 0.92 on the standard curve metric, with correct classification above eighty-five percent on both hazard and safe units in validation. Hazard grew markedly as rainfall intensity increased, expanding the high-hazard footprint on the county map. Medium to high risk zones concentrated in the Jiuyi Mountain area and two named townships, matching field observations. The authors present the hybrid as a less subjective, scalable template for county disaster planning.
