遥感影像信息在活动断裂研究中的应用
|
摘要
遥感图像不仅从宏观上展现了活动断裂与其它活动构造的影像全貌 ,而且直观地揭示了活动断裂的影像信息 ,为分析断裂的活动状态及其与地震活动的相关性 ,为识别发震构造与强震的孕育地段提供了丰富的信息。而遥感技术方法本身的优势 ,又使得遥感构造研究具有了视域开阔、信息丰富直观、处理方法多样、易于综合分析、获取成果迅速等特点。从直观上讲 ,活动断裂遥感影像标志主要有色调、构造形态、断层三角面、地貌及水系等几个方面 ,归纳起来主要是垂直错动标志和水平错动标志。从多方面总结了活动断裂在遥感影像上的表现特征和识别标志 ,并为今后活动断裂以及地震研究中遥感影像信息的应用提出了一些有效方法和途径。
Remote Sensing image not only expresses the panorama of active faults and active tectonics on macroscopic view, but exposes the image information of active faults directly. It offers profuse information for analysing the active states of faults,their correlation with seismicity,the tectonics developing earthquakes and strong earthquake preparation. Remote sensing technique itself has predominance,which make remote sensing tectonic research get many characteristics such as pantoscopic,rich and direct informations,multiplicate methods, easy colligate analysis, achieving production rapidly and so on.Intuitively remote sensing image signs on active faults mostly include hue, tectonic infiguration,triangle surface of faultages,physiognomy and water system,etc. To put it briefly, they are vertical dislocation sign and horizontal dislocation sign.The paper summarizes active faults' manifest characteristics and identification signs on remote sensing images in many ways. It also supply some effective methods and approaches for the application of remote sensing image information in the research of active faults.
