摘要
将CBERS-02B星CCD图像与震前ETM图像相结合,调查"5·12"汶川地震极重灾区湔江流域的堵江灾害,解译堵江长度为120.6～2665.8m的共54段,分析了堵江分布与映秀—北川逆冲大断裂的关系。结果表明02B星图像与其它高分辨率图像相结合可进行大型地质灾害解译。
Using CCD images of the CBERS - 02B satellite in combination with pre - earthquake ETM images, the authors investigated the river - damming disaster of the Jianjiang River valley, a severely earthquake - stricken area of the ＂5 ·12＂ Wenchuan strong earthquake, interpreted 54 river - damming segments totally 120.6 ~ 2 665.8 m in length, and analyzed the relationship between the distribution of the river - damming segments and the Yingxiu - Beichuan great reverse thrust. The results show that images of the 02B satellite in combination with other high - resolution images can be used to interpret large -scale geological hazards.
