The application of remote sensing image on structure character analysis of Turpan-Hami basin

Remote sensing image has such characteristics as macroscopical, real and clear structure trace, so it is an efficient method to apply remote sensing image to interpreting works, in order to study seismic geology. In this paper, we attempt to apply remote sensing image visual interpretation results to study the active structure characteristics in Turpan-Hami basin, and discuss the earthquake activity rules in this region. On the one hand, after geometric correction and mosaic we merge 4, 7, 1 bands with the 8th band of ETM+ images, gaining a color image with 15-metre resolution. Then we do some processing such as enhancement and feature extraction, in order to make the linear feature clearer. On the other hand, we analyze the image with DEM, producing 3D effect. Both them are very useful for us to study the geological structure and active faults. In our works, we primarily analyze and study the linear structure zone in Turpan-Hami basin with texture analysis and DEM, extracts the linear structure character of this region. Then we have a new understanding for double bow-backed structure, and do some study about the correlation of this special structure and the earthquake activity rule in this region
