Abstract: China is a large hydropower country, and the early identification, monitoring, and early warning of geological hazards in hydropower stations have always been a top priority for the normal operation of hydropower stations.Currently, modern remote sensing technologies such as optical remote sensing, InSAR, and LiDAR have been widely used in geological disaster identification, monitoring, and early warning, becoming important technical support means.Summarizes and analyzes the characteristics of different remote sensing technologies and their applications in the field of geological disasters, and proposes the construction of an integrated “sky-sky-earth” early identification and monitoring system for landslide disasters in hydropower stations, as well as remote sensing technology methods for dynamic monitoring of dam deformation in the reservoir area of hydropower stations, providing reference and reference for the prevention and control of geological disasters in hydropower stations.
