摘　　要：根据遥感技术在断裂构造研究中具有宏观性、直观性、时效性等特点,通过波段相关性分析方法(OIF)选取最佳组合波段,运用高分一号、DEM影像资料,结合前人研究成果及选定的野外考察地区资料,对展布于大别山腹地的梅山-龙河口断裂中西段进行分析研究。结果表明:该断裂西北段的铁冲乡—梅山水库—响洪甸水库沿线在遥感影像上显示极好的线性特征,运用DEM生成的山体阴影图可清晰识别深切沟谷、沟槽、陡坎等。最后,通过野外调查,发现梅山-龙河口断裂倾角较大或近直立,从断面特征及破碎带胶结程度来看,该断裂第四纪以来具有一定程度的新活动。Remote sensing technology has a macro, intuitive, timeliness in fault structure study. In this paper, the best bands combination is selected by the correlation analysis method of band （ OIF ）, using GF - 1, DEM image data, combined with the results of previous study and the selected field survey data, analysis and research on the distribution in Dabie Mountain hinterland with middle and west part in Meishan -Longhekou fault. Results show excellent display linear feature in Remote image along the Tiechong Village - Meishan reservoir - Xianghongdian reservoir, using DEM to generate the shadow of the mountain can clearly identify the deep valleys, steep ridges and grooves. Finally, through field investigation, Meishan--longhekou fracture dip angle is found bigger or sub-erect; according to the section feature and fracture zone of cementation, there are some new activities with a certain degree of the fault since quaternary.
