摘　　要：遥感解译分析是断裂调查和活动性研究的重要工作内容,通过清晰、完整的断裂线性影像判读并结合实际验证调查能够获得断裂构造展布、结构、规模和活动特征等多方面的参数。浑河断裂带发育于沈阳、抚顺及其以东的辽东山地,其Google Earth卫星数据分辨率可以达到1~2.5m至亚米级,客观上提供了进行浑河断裂带遥感解译分析的条件。分析表明,浑河断裂带可以划分为沈阳段、抚顺段、章党—南杂木段和南杂木—英额门东段等4个不同的断裂段,除沈阳段以外,其它各段均表现出清晰的断裂线性特征,对于微地貌形态具有比较明确的反映。抚顺段和南杂木—英额门东段均控制了浑河河谷的发育,但不同的是,抚顺段北支较之南支规模更大、活动性更强,章党—南杂木段和南杂木—英额门东段影像可辨识度较高,微地貌变化稳定、连续,可能具有较新的第四纪活动性。Remote sensing analysis is an important work for the fault investigation and activity research,Through clear,complete faults linear images interpretation and combined with actual verification surveies,the fault characteristics such as distribution,structure,scale and activities could be gained.As developed in Shenyang,Fushun and the east of Liaodong mountains,the resolution of Google Earth remote sensing data along the Hunhe fault zone can reach a level of 1-2.5m or more less,objectively provide the condition to carry out remote sensing analysis for the fault.By the analysis,the Hunhe fault zone is divided into 4 different segments of Shenyang,Fushun,Zhangdang-Nanzamu and Nanzamu-Yingemen east,besides of Shenyang segment,the others all show clearly linear features and have comparatively clear reflections for micro morphology.Both of Fushun and Nanzamu-Yingemen east segment controls the growth of the Hunhe river valley,but on the contrary,the north branch is bigger than the south of Fushun segment,meanwhile,the image recognizabilities of Zhangdang-Nanzamu and Nanzamu-Yingemen east segments are higher,the micro morphology changes are stable and continuous,shows these 2 segments may have a relatively new Quaternary activities.
