“5.12”地震次生地质灾害分析——以青川、平武县为例
|
摘要
"5.12"汶川特大地震诱发了大量的次生地质灾害,造成了山体大面积滑坡、崩塌、泥石流及堰塞湖等,给人民生命财产造成了重大损失。在对平武、青川县地质、水文、气象条件等地面调查的基础上,以多源遥感数据为信息源,结合3S技术,解译了次生地质灾害及潜在地质灾害体,并进一步探讨了震后次生地质灾害的发生、分布规律。研究成果对灾后重建、高山峡谷地震多发区的防灾及灾害遥感机理研究具有借鉴意义。
The "5.12" Wenchuan earthquake induces a large number of secondary geohazards,causing large-scale mountain landslide,collapse,debris flow,barrier lakes and other secondary disasters.The earthquake has caused people's life and property to loss heavily.Through the ground investigation of basic geological,hydrological and meteorological conditions,etc.,in Pingwu and Qingchuan regarded multi-source remote sensing data as the information sources and combined with 3S,the paper interprets the secondary geohazard and potential geohazard body,and furthermore talks about occurrance and distribution of secondly geohazard after-earthquake.The findings should be good reference for the reconstruction and prevention for disaster-prone area and the mechanism on disaster remote sensing research frequent earthquakes
