2010-04-14 7时49分, 中国青海省玉树藏族自治州结古镇附近(北纬33.2°, 东经96.6°)发生了Ms7.1级地震。利用灾后高分辨率航空影像, 结合震前北京一号小卫星、SPOT正射影像, 在分析地质构造背景基础之上, 从房屋建筑物损坏情况、生命线工程的损毁程度以及次生灾害的调查等方面开展了灾情遥感应急监测工作, 为地震应急决策救援提供宏观、科学(定性、定量)的辅助决策依据。

At 7:49 am on April 14, 2010, an earthquake (Ms 7.1) originated (33.2°N, 96.6°E) near Jiegu Town, Yushu Tibetan Autonomous Prefecture, Qinghai Province, China. After the earthquake, we analyzed the geological structure of the disaster re-gion based on the “Beijing-1” images. Using the aerial images after earthquake with high resolution (0.4m) and SPOT or-tho-images, we monitored urgently the disaster situation, including the damage degree of the buildings, the damage degree of the lifelines, the field disasters and the secondary disasters. The result could provide the important basis for emergency management and rescue mission.
