| 摘 要： | 2003年7月13日，三峡库区湖北省秭归县沙镇溪镇千将坪村发生特大型滑坡灾害后，利用先进的数字遥感技术，结合滑坡前
后的高分辨率的遥感数据、地形图资料和野外所测的GPS控制点，制作出研究区滑坡前后的数字高程模型(DEM)，同时采用合理的图
像处理技术，获得了滑坡前后正射影像图。利用三维可视化技术，采用人机交互解译滑坡，详细的对比解译滑坡前后的影像，分别
对滑体的滑动方向、距离和堆积体面积进行了定量计算，结合勘查资料估算出其体积约为1 500万方，综合地质学、灾害学原理和
地理空间信息技术等科学分析了千将坪滑坡的形成条件，认为千将坪在“7.13”滑坡之前为一特大型顺层古滑坡，而“7.13”滑坡
是古滑坡的大规模复活，三峡库区蓄水和降雨综合作用是促使滑坡复活的主要诱发因素。

| Abstract: | A gigantic landslide happened at Qianjiangping Village of the Three Gorges area in Zigui County, Hubei
Province on July 13,. 2003. Combining advanced remote sensing digital technique with the relief map data, the
authors set up the DEMS before landslide and after landslide of this area. On the basis of these high-resolution
satellite images, a 3D terrain model was constructed. Interactive interpretation was employed to get
characteristic features, the slide direction and the distance between various parts of landslide were calculated,
and then the volume was estimated, which is 1.5×107m3. Making good use of geological data, disaster theory and
GIS, the authors found out the caused for Qianjiangping landslide. It is believed that the main triggering factors
seem to have been the sluice of the Three Gorges and continuous heavy rainfall. |
