Abstract :
According to the analysis of the tectonic characteristics of thrust belt in the Longmen Mountain, the present study aims to build a methodology to extract liner fault structures in the study area. The methodology is an approach which includes automatic extraction of major faults based on combined calculation of landform factors from the SRTM-DEM and revision of the automatic extraction result according to remote sensing images and geologic data. Therein, these landform factors including elevation, slope, aspect and variation of aspect, slope of slope (SOS) and slope of aspect (SOA). The compound method, including the spatial analysis techniques based on SRTM-DEM, interpretation of remote sensing images, and some geosciences´ researches, provides strong technical support to achieve the quantization of the morphotectonics research.
