摘　　要：基于ETM+、ASTER GDEM及其衍生坡度数据,通过影像增强处理和阴影、坡度与三维分析,有效增强了断裂影像,建立了博州地区断裂判读标志,解译出研究区存在北西、北西西、东西、北东等走向主要断裂20余条,其解译结果与地质资料基本一致。On the basis of ETM ＋ image, ASTER GDEM data and its slope data, some different methods, such as image enhancing, analysis of shadow of mountain, analysis of the surface slope and three-dimensional analysis, are efficient to highlight image features of faults. Thus the indicators for interpreting fault in Bortala Mongol Autonomous Prefecture were established. More than twenty main faults of NW, NWW, EW and NE trending surrounding the Bor- tala Prefecture were discovered. The interpreting results show a consistency with the local geology map.
