摘要： 本文在综合分析活动断裂遥感影像特征的基础上, 主要研究了活动断裂与隐伏断裂调查中遥感图像处理。基于SAR影像、 ETM+影像、 SPOT-5影像及高精度DEM数据, 运用SAR图像与ETM+多光谱图像融合方法、 ETM+图像纹理特征和光谱特征组合增强方法等, 结合断裂周围高分辨率影像及其三维影像, 综合分析解译了济南市周边活动断裂, 为该地区地震地质调查和精确定位活动隐伏构造提供了依据。

Abstract: Active or Concealed faults can form plenty of tectonic physiognomies, controlling the physiognomic difference and was twined by land deformation and water system synchronous turn around, which locate in both sides of the active or concealed fault. In virtue of the characters appearing on the remote sensing image, the active or concealed fault thus can be recognized. The paper focused on displaying the disposal technologies of active and concealed faults in the remote sensing images, and implemented these technologies to process images with different special resolution for the city of Jinan and surronding area. The study can provides the basic data for seismic geology survey and exactly locating the active and concealed faults.

Key words: Active faults, Fusion, Enhancement, Radarsat image, Digital Elevation Model (DEM), Three-dimensional topographty.
