摘　　要：文章将高分二号(GF-2)和高景一号(Superview-1)等高分辨率卫星影像应用于精河县滑坡应急调查中,采用二、三维一体化技术解译疑似滑坡点20处,并以GF-2号卫星数据为基础,结合1∶10万地质图勾画了研究区地层岩性分布图。由此,总结出滑坡点主要沿精河分布,坡体坡度一般介于42°~60°,并大部分发生于头苏泉组(D2ts)地层中的规律,为今后地质灾害的应急调查提供参考、示范。This paper aims to investigate landslides in Jinghe County,based on the high resolution image provided by GF-2 satellite and Superview-1 satellite. For the investigation,the 2D-3D integration technology was used to explain 20 suspected landslides. Data acquired by GF-2 satellite and geological map with a scale of 1∶ 100 000 were used to plot the formation lithology distribution map of the study area. The analysis result indicates that the landslide are mainly distributing along the Jinghe river,and the angles of the slope are normally between 42° to 60°. The majority of landslide were happened in D2 ts stratum. This study can provide reference and example for for future emergency investigation of geological disaster.
