摘要: 云南省祥云县鹿鸣河流域地形复杂,地质构造发育且岩土体破碎,人类工程活动强烈,地质灾害极其发育.为探究评价精度更高的区域地质灾害风险评价方法,在研究现有评价模型的基础上,采用“AHP-信息量”耦合模型,开展鹿鸣河流域地质灾害易发性、危险性、易损性和风险评价.研究结果表明:地质灾害高风险区面积108.06 km2,占全流域面积的54.85%;中风险区面积7.90 km2,占全流域面积的4.01%;低风险区面积81.04 km2,约占全流域面积的41.14%.通过对耦合模型的精度检验证明,评价模型满足精度要求.

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.
