中文摘要：

柯坪逆冲推覆构造系是西南天山最新构造变形的产物，研究其晚第四纪活动性对认识西南天山褶皱-逆断层变形与强震发生的关系有重要的意义。文章通过对柯坪构造系3个典型地点的ETM＋和SPOT-5 Pan的处理和分析，解译了这些地点的层状地貌面、活动逆断裂的位置及几何展布，以及活动褶皱的展布形态。通过野外考察，验证了解译的可行性，总结了阴影纹理结构和色调标志、地层标志、地形地貌标志、冲洪积扇的排列形态和规模标志、水系和冲沟标志等解译标志。应用这些解译标志取得了关于柯坪逆冲推覆构造系最新构造变形的初步认识。

英文摘要：

Kalpin thrust tectonic system is the outcome of Late Quaternary tectonic deformation of the south Western Tianshan. It is very significant to investigate its Late Quaternary activity in order to know the relationship between deformation of the south Western Tianshan fold-thrust fault and strong earthquakes. In this paper,we firstly process and interpret ETM＋ images which are fused with SPOT-5 Pan at three typical sites. Then we obtain the interpretation map of bedded geomorphologic surfaces,the location and distribution of active faults and active folds. Based on field investigation, it is testified to be feasible for using the fused image to interpret late tectonic deformation. At the same time, tectonic interpretation symbols are summarized such as shadow, texture and hue symbol, stratum symbol, distribution and size of alluvial and proluvial fan symbol, gully and river system symbol. At last, we use these symbols to interpret fused images of other area, and get some preliminary determinations of Late Quaternary tectonic deformation of the Kalpin thrust tectonic system. The determinations are as follows ： （ 1 ） bedded geomorphologic surfaces are generally divided into five episodes,which shows the activity of faults in several times; （2） the most of fault scarps continuously wavily distribute on the middle top of the alluvial and proluvial fan,which corresponds with characteristics of the low angle thrust fault; （3）there are young terraces near the outlets of Quaternary neonatal folds, which reveals Late Quaternary activity of the neonatal folds.
