Based on the "Gaofen +", this paper explores the emergency analysis of the Jinsha River landslide disasters on October 11 and November 3, 2018, with the "Gaofen + geological disaster" model, and uses the high-resolution remote sensing image of the disaster area before and after the disaster to interpret the landslide. According to the basic disaster information of the disaster, the characteristics of pregnancy disaster and deformation and creep before and after the disaster are analyzed. The hidden dangers are investigated in the Baige Lake and surrounding areas after the disaster. The suspected cracks and secondary landslide hazard points on both sides of the barrier lake are identified, and road accessibility analysis of disaster areas after the second landslide is carried out. The results show that the "Gaofen +" model has great potential for the application of natural disasters such as the Jinsha River landslide, disaster monitoring and emergency rescue roads.
