摘　　要：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。运用高分一号影像进行融合、DEM数据建立定向光照模型,并结合前人研究成果,对展布于大别山腹地西北的梅山-龙河口断裂进行分析与研究。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,结合DEM生成的山体阴影图分析,可清晰识别断层沟谷、垭口、三角面。最后,通过野外调查验证,发现梅山-龙河口断裂倾角较大或近直立,由断面特征及破碎带胶结程度来看,该断裂具有一定程度的新活动。According to the macro, intuitive, timeliness and other features of remote sensing technology in the structure research, this paper uses GF-1 image and DEM data to establish directional illumination model, and studies the Meishan-Longhekou fracture located in the northwest hinterland combining with the field survey data of previous research. The results show that the northwest section of fracture along the Tiechong Village- Meishan reservoir- Xianghongdian reservoirin display linear feature in remote sensing image; by using the shadow of the mountain generated by DEM, deep valleys, steep ridge and triangle can be clearly identified. Finally, through field investigation, the author find that dip angle of Meishan-longhekou fracture is bigger or suberect, and the fault has new activities with a certain degree from the section feature and fracture zone of cementation,.
