【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。更多还原

【Abstract】 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.更多还原
