中巴02B卫星数据地质灾害调查典型应用

中巴02B星成功发射以来，已在平原地区的多个领域获得广泛应用。汶川地震后， 02B星获取了自震后第2天-5月13日至6月14日的灾区影像数据。这些卫星数据为各部门的抢险救灾工作提供了现势资料。本文介绍02BCCD数据图像与震前ETM图像结合调查5.12地震极重灾区湔江流域的堵江灾害，共解译了堵江长度为120.6m~2665.8m的54段堵江，并分析了堵江分布与映秀-北川逆冲大断裂的关系。02B卫星图像与其它高分辨率遥感图像配合可进行大型地质灾害解译。

THE TYPICAL APPLICATION OF CBERS-02B DATA FOR GEOLOGICAL DISASTERS

Since the CBERS-02B satellite launched successfully data of which widely used in several fields in the plain areas. After 2008-05-12 earthquake 02B satellite had captured the image data from the second day after the earthquake-13th May to 14th June, which provided the period conditions image for emergency disasters rescue of varies organizations. This paper introduce the interpretation results of dammed river disasters caused be 5.12 earthquake in the Jian river basin- the most serious disaster region suffered from the earthquake by using 02BCCD compared with EIM image before the earthquake. 54 sections of river each 120.6m~2665.8m in length had been interpreted and the relation between the distribution of dammed lakes and Yingxiu-Beichuan great thrust faults were analyzed. With 02B image combined with other high resolution satellite the large scale geological disasters can be interpreted.
