汶川地震地质灾害遥感调查与空间特征分析
|
摘要
采用多源遥感数据、DEM数据和地形图等资料,对汶川地震地质灾害遥感进行了解译和调查。查明了汶川县境内地震地质灾害体的位置、类型、规模、边界等形态特征;论述了地震崩滑地质灾害溃滑型、溃崩型、抛射型、剥皮型、震裂型遥感影像特征;分析了汶川县境内地震地质灾害与地震断裂带、河谷地貌、高程、坡度、岩性等空间分布关系。研究表明,多源数据在地震地质灾害详细调查中具有采集范围广、速度快,可解译程度高、时效性高等优势,能较快、较好地应用于地震地质灾害突发性、区域性地震地质灾害遥感调查工作。
By using multi-source remote sensing data,DEM data and topographic maps,the remote sensing of seismic geologic hazard in Wenchuan County was interpreted and investigated.It has identified characteristics of geological hazards such as location,type,size and boundaries,summarized seismic landslides in ulcer slip type,ulcer collapse type,projectile type,peeling type and shattered remote sensing image features.The relationship between seismic geologic hazard and earthquake fault,valley topography,elevation,slope and lithology was analyzed.In the investigation of geological disasters in the earthquake,the high-resolution satellite images and aerial photo data have advantages such as high-speed and wide range collection,high-degree interpretation,higher timeliness,and so on.The high-resolution satellite images and aerial photo data can be applied in dealing with unexpected geological disasters in an earthquake,in a regional seismic survey of geological hazards.The advantage of multi-source remote sensing data,especially the high-resolution satellite images and the aerial photography,was summed up in the detailed investigation of seismic geologic hazard.
