Abstract: Due to the widespread distribution of metamorphic rocks with high porosity and easy softening when exposed to water along the banks of the Duhe River Basin in northwest Hubei, landslides are easily induced in areas with developed water systems due to factors such as rainfall and human engineering activities. Therefore, guided by the typical metamorphic rock mountain reservoir bank in the Duhe River Basin, a regional landslide vulnerability assessment was performed. The population density, age structure, risk prevention awareness, gender ratio, building type, transportation facility type, and land use type are selected as vulnerability assessment indicators for the study area. By using the Analytic Hierarchy Process to determine the weights of various vulnerability assessment indicators and combining the weights of each indicator with the quantified vulnerability assessment indicators through the construction of a linear weighted model, the vulnerability assessment of landslide disasters in the study area is completed, providing a basic basis and technological support for local disaster prevention and control management.
