At last , the paper interprets the geological background of the forming of landslides , and reveals the landform , stratum , lithology and geologic structure based on the etm + image . and also , the paper interprets the location and distribution of the specific disaster bodies based on the quickbird image . through the analysis of the extracted information , the paper considers : the geologic structure of fengjie county is complex , and lithology is crashed ; the terrane in the canyon segment is fairly stable ; the terrane in some segments of the southern bank will be less stable after the water is stored , because the rock is in the same direction and is apt to slip with human project
最后在etm +图像上对滑坡发育的地质背景进行解译，提取了地形、地层岩性、地质构造等信息，在quickbird影像上详细地圈定了滑坡灾害体的实体位置及发育范围，通过对所提取信息进行分析，本文认为，奉节县地质构造复杂，岩性破碎；峡谷段岩层稳定性较好；南岸部分地段为顺向岩层分布区，人类工程活动容易诱发顺层滑坡，蓄水后库岸整体稳定性下降。
