According to filed investigation on the engineering geological conditions of Wudongde reservoir area in Jinsha River, we selected slope angle, formation lithology, geological structure, bank slope structure and other 6 factors to assess the bank slope landslide hazard. Fuzzy comprehensive evaluation (FCE) model and modified analytic hierarchy process (AHP) are employed for the hazard assessment. Results revealed that the Wudongde reservoir area can be divided into high risk area, medium risk area, low risk area, and extremely low risk area, respectively accounting for 6.64%, 5.77%, 60.20%, and 27.39% of the whole area. The result provides support for the prevention, reduction, and governance of bank slope landslides.
