遥感在汶川地震地质灾害评估中的应用

Remote sensing application in the geologic disaster evaluation of Wenchuan earthquake

首先介绍了遥感技术的优点以及地震诱发的几种次生地质灾害,然后结合汶川Ms8.0级地震诱发的地质灾害和已收集到的灾区遥感数据,分别说明了利用光学遥感和雷达卫星数据进行评估的方法和各自的特点,并应用这些方法得到了灾区的专题信息图,最后总结了遥感在地震诱发地质灾害评估中存在的问题。

This paper introduces the advantages of remote sensing technology as well as several secondary seismic- induced geological disasters. And based on Ms8.0 Wenchuan Earthquake - induced geological disasters and the remote sensing data of seismic region, evaluating methods that the optical and radar remote sensing satellite data has been introduced respectively, and thematic information map has been gotten by the methods above. Finally the problem existing in the evaluation of the earthquake- induced geological disasters was surnmed up by remote sensing.
