Abstract：This study focused on the Shaoguan and its surrounding areas,utilizing a total of 546 scenes of ascending and descending SAR data from the LT-1 Satellite from July 2023 to March 2024.Using the Stacking-InSAR method,the paper conducted early identification research on landslide hazards,and summarized 11 remote sensing identification features,including micro-topography,deformation damage signs,and primary threat objects.By combining optical remote sensing images with a resolution better than 1 meter from April 2024 and field verification,the effectiveness of LT-1 in identifying landslide hazards in vegetation-covered areas was validated.The results show that 116 suspected landslide hazards were identified by using LT-1 satellite,and 70 sites were confirmed as potential risks through field verification,with an identification accuracy of 60.3%.This indicates that the Stacking-InSAR method based on LT-1 satellite can effectively detect the distribution of landslide hazards,and provides critical technical support for the early identification and comprehensive defense against landslide hazards.
