Water level fluctuations in the lower Jinsha River reservoirs exhibit clear periodicity, progressively weakening slope stability over time. Traditional methods based on localized monitoring are insufficient for capturing large-scale landslide activity, and previous studies have lacked systematic analyses of multi-factor interactions across varying temporal scales. This study investigates the spatiotemporal evolution of reservoir and non-reservoir landslides from 2010 to 2024 across major reservoirs and surrounding areas. Landslides mainly occur linearly along the river channel, with reservoir landslides significantly more frequent and larger, especially during construction and initial impoundment. Upstream reservoirs (Wudongde and Baihetan) show more frequent and larger landslides, primarily due to steep terrain and active tectonics. Notably, landslide activity generally declined 3 to 5 years after the start of reservoir operation, indicating the combined influence of mitigation efforts and natural slope adjustment.
