  • 摘要: 本文系统分析了高分辨率遥感在活动断裂调查中应用的技术现状、工作流程,梳理了各类遥感数据的要求、适用条件和处理方法,总结了活动断裂的遥感解译方法、解译要素和测量参数,并通过实例解析了一些典型的断错地貌,给出了相应的遥感特征. 基于资源三号卫星的立体像对和影像,判读了大青山活动断裂的几何特征和活动特性. 结果表明: 人工改造较大的地区宜收集早期遥感影像,利用不同波段间地物光谱的差异来增强隐伏活动断裂的信息,使用空间增强方法来识别断层陡坎等线性构造;雷达数据多极化分解是检测隐伏构造信息的有效方法;由宏观信息向局部信息追踪是活动断裂解译的有效途径;将遥感影像与数字高程模型(DEM)联合可进行活动断层参数的高精度测量. 本文结果可为活动断裂大比例尺、定量调查提供参考.

     

    Abstract: This paper analyzes systematically the technology status-quo and work flow of high resolution remote sensing in application of the active fault investigation,combing with the various of remote sensing data requirements,applicable conditions and processing methods,and summarizes the interpretation method,interpretation elements and measurement parameters of remote sensing for active faults. Furthermore,some typical features of faulted geomorphologies are analyzed,and the corresponding remote sensing characteristics are described. Taking the Daqingshan as a test,the geometric features and activity characteristics of the active faults in the area are interpreted by using the stereoscopic image and image of ZY3,meeting the needs of quantitative research on the active structure. The results suggest that the old remote sensing image should be collected in the surfaces deeply changed by city development,and the spectral differences in different bands can be adopted to enhance the information of buried faults,meanwhile, the spatial enhancement methods can be used to identify fault scarp. Multi-polarization radar data decomposition is an effective method for the detection of buried structure features,and tracking from the macro information to the local information is also an effective way to make active faults interpretation. The combination of remote sensing images with DEM will improve the measurement precise of active fault parameters. The results provide reference for the large-scale and quantitative investigation of active faults,and for the researchers to grasp the relevant technology of remote sensing application as soon as possible.
