【摘要】：首先分析了获取数字高程模型(DEM)的高分遥感立体测量、合成孔径雷达干涉测量技术、激光雷达测距技术和运动重建技术等技术手段,以及现阶段高空间分辨率数字高程模型(VHR DEM)提取技术的主要特点,实际应用中需根据研究区地形地貌特点选择合适的VHR DEM获取技术;然后,结合最新研究成果着重阐述了VHR DEM在活断层识别及几何结构分析、同震位移与累积位移获取和古地震研究等领域的最新应用;最后指出,VHR DEM由于其高精度、高空间分辨率的特点,正逐步改变传统活断层的研究方法,使得对活断层的研究进入到了前所未有的精细化水平.
[Abstract]:First of all, the techniques of acquiring the digital elevation model (DEM), such as high remote sensing stereo measurement, synthetic aperture radar interferometry, lidar ranging and motion reconstruction, are analyzed. As well as the main features of the (VHR DEM) extraction technology of high spatial resolution digital elevation model at present, it is necessary to select the appropriate VHR DEM acquisition technology according to the topographic and geomorphological characteristics of the study area in practical application. Then, the latest applications of VHR DEM in active fault identification and geometric structure analysis, coseismic displacement and cumulative displacement acquisition and paleoseismicity research are described in combination with the latest research results. Finally, it is pointed out that because of its high precision and high spatial resolution, VHR DEM is gradually changing the traditional active fault research method, which makes the research of active fault into an unprecedented level of refinement.
