【摘要】 遥感影像从宏观上反映活动断裂的影像全貌,还能动态地研究活动断裂的发生、发展及时空演化规律.本文以昌化-普陀断裂为例,利用遥感构造分析技术对其构造特征进行了全面的解译和识别.采用图像增强与融合等处理方法,增加了图像的立体感,提高了遥感影像清晰度和解译精度.同时通过收集区域重力资料、浅层人工地震资料以及断裂附近地区的钻孔资料,并结合野外实地考察,对解译的结果进行了验证,利用遥感影像判读的结果与实际结果一致性很好.本研究成果对杭州地区的大型工程建设、地震预报以及新构造运动等研究具有一定的借鉴意义.更多还原

【Abstract】 Remote sensing images express not only the panorama of the active faults and active tectonics on macroscopic view,but also dynamic occurrence,development and temporal-spatial evolution of active faults.In this paper,the Changhua-Putuo fault zone was interpreted and recognized completely with the technologies of structural analysis based on remote sensing.The definition and precision of the remote sensing images were greatly improved by image enhancements and fusions.At the same time,we collected gravity anomalies data,shallow artificial seismic exploration data,borehole data and historical earthquakes and so on to validate the interpreted results.The results that interpreted from the remote sensing images showed a high consistency with the field survey and will offer significance to large engineering project,earthquake forecasting and the study of neotectonic research.更多还原
