The frequent occurrence of geological disasters is an important geological and environmental problem in the southeastern region of Tibet. The source areas of geological disasters in this area are mostly located in high mountain and canyon areas, with severe vegetation coverage and limited human access. Traditional methods such as manual investigation are difficult to achieve early identification of geological and environmental problems characterized by high-level and hidden geological hazards in this area. Therefore, using multi-source comprehensive remote sensing technology to carry out comprehensive identification and investigation of geological hazard hazards in the southeastern region of Tibet, summarizing a set of comprehensive remote sensing identification technology methods suitable for high-altitude deep valley areas, and taking reasonable prevention and control measures are of great significance for solving geological environmental problems in this area. On the basis of analyzing the background of geological disasters, using InSAR technology to extract surface deformation information, combined with multi temporal high-resolution optical remote sensing images for comprehensive remote sensing geological hazard identification, has the advantages of efficiency and economy, and can accurately monitor the formation, occurrence, and development process of geological hazard hazards. For important slope zones, significant results have been achieved in identifying high-level and hidden disaster hazards and conducting detailed investigations using unmanned aerial vehicle LiDAR and three-dimensional oblique photogrammetry technology. At the same time, in response to the development characteristics of landslide geological hazards in this area, measures such as slope cutting and weight reduction, slope reduction and potential reduction, slope toe protection and reinforcement, slope surface interception and drainage waterproofing, combined with greening and monitoring measures, can be taken to eliminate landslide masses, ensure slope stability, and improve the local environment.
