Abstract: The geological hazards are extremely developed in Luming River Basin of Xiangyun County, Yunnan Province, with complex topography, developed geological structure, fragmented rock and soil bodies, and strong human engineering activities. To explore a more precise method for assessing regional geological hazard susceptibility, danger, vulnerability, and risk, this study adopts a coupled model of analytic hierarchy process and information value (AHP-IV coupled model), building upon existing evaluation models. The results of the study show that the high-risk zones cover an area of 108.06 km², accounting for 54.8% of the total basin area; medium-risk zones cover 7.90 km² (4.01%), while low-risk zones span 81.04 km² (41.14%). Model validation confirms that the coupled model meets the required accuracy standards.
