【摘要】 北东走向的马金-乌镇断裂是浙北地区一条重要的断裂,该断裂及周边地区曾有多次地震发生(M≤5),然而由于受第四系覆盖等客观条件所限,关于该断裂的空间展布方向和活动性仍存在着争论。本文以马金-乌镇断裂为例,采用图像增强和融合等处理方法进行遥感信息提取,同时结合野外调查、断裂活动年代样品的采集和测定、航磁数据以及浅层人工地震勘探等多元信息,对马金-乌镇断裂进行了详细的研究和年代鉴定。研究结果表明,遥感技术不仅有效地查明了断裂的空间展布,同时指导了浅层人工地震勘探的测线布置以及推断断裂的活动时代和运动性质,为城市规划和建设提供基础数据和参考依据。更多还原

【Abstract】 The NW-SE trending Majin-Wuzhen fault(MWF) is a major fault in Hangzhou region,and there are several earthquakes(M ≤5) took place near the fault zone and its suroundings.However,because of the Quaternary and other objective conditions,the distribution and activity of the Majin-Wuzhen fault is still in discussion.In this paper,the definition and precision of the remote sensing images were greatly improved by image enhancements and fusions.At the same time,we collected aeromagnetic anomalies data,shallow artificial seismic exploration data,ERS measured data,field investigation and so on to validate the interpreted results.The results show that the multi-resource information can identify the spatial distribution of the fault,guide the line layout of shallow artificial seismic exploration survey,judge the fault activity characteristics and offer significance to city planning and construction.更多还原
