摘要
利用CBERS-02B星CCD和HR数据,采用数字滑坡技术,制作出滑坡地区的数字高程模型;采用三维可视化技术,结合当地的地质环境构造条件,用人机交互方式,分析"5·12"地震中唐家山至北川县城堵江河道滑坡发生的面积、运动方向、滑坡形成条件和诱发因素。
Based on CCD and HR data of CBERS -02B satellite and adopting digital landslide technique, the authors set up the DEM of the landslide area. Using the 3D visualization technique and the interactive interpretation method, combined with geological environment and structure conditions of Beichuan county, the authors also scientifically analyzed the area, moving direction, conditions and inducing factors for landslide formation along the blocking river course from Tangjiashan to Beichuan county seat.
