高位地质灾害具有强隐蔽性、强破坏性、难排查性等特征，近年来在我国西南山区频频发生，给山区居民造成了严重的人员伤亡和财产损失。以国产高分二号与北京二号等国产遥感卫星影像为数据源，对“10·11”金沙江高位滑坡开展灾情应急监测，分析了滑坡致灾情况、致灾演变及灾前蠕变特征，对灾后堰塞湖周边隐患灾后开展二次排查，查明了堰塞湖全域存在疑似裂缝隐患2处、滑坡隐患16处及5淹没区受损情况。结果表明国产遥感卫星对国家重特大地质灾害应急监测发挥了重大作用。

High-level geological disasters are characterized by strong concealment, strong destructiveness, and difficulty in investigation. These disasters have frequently occurred in the mountainous areas of Southwest China in recent years, thereby causing serious casualties and property losses to mountain residents. Remote sensing technology has the advantages of short response time, intuitive image, high resolution, and extensive monitoring range. An image is highly achievable, easy to obtain, low cost and reliable, and can be "acquired". On the basis of the Gaofen-2 and TRIPLESAT (Beijing-2) images as the data source, this study conducted an emergency monitoring of the "10·11" Jinsha River high-level landslide and analyzed the landslide disaster situation, disaster evolution, and pre-disaster creep characteristics. The second investigation was performed after the disaster in the vicinity of a barrier lake. A total of 2 suspected cracks in the entire area of the barrier lake, 16 hidden dangers in the landslide, and 5 inundation areas were found. Results showed that domestic remote sensing satellites demonstrate considerable application prospects for the emergency monitoring of severe geological disasters.
