摘　　要：利用光谱信息丰富的常规光学遥感(Landsat-7 ETM)和Google earth影像作为主要数据源,运用ETM1,4,7波段进行假彩色图像合成,综合两种不同的影像于ArcGIS平台上对郯庐断裂构造特征进行分析。首先确定线性构造,通过线性构造周围水系、地形特征推测断裂的存在,得到研究区域内郯庐断裂遥感影像图,基本确定郯庐断裂的基本格架,主干断裂可分为山东境内构成"两垒夹一堑"的四条主干断裂,宿迁-庐江的隐伏断裂,庐江-桐城断裂带。This paper combines the information-rich spectrum of conventional optical remote sensing image（Landsat-7 ETM） with the Google earth image as the main data source,utilizes ETM1,4,7 band for false color image synthesis,and integrates two different images on the characteristics of the study area for analysis.In the beginning,it identified the linear structure,speculated the existence of fracture through the water system and topographical features around the linear structure,acquired the remote sensing image map of Tanlu fault in the researched region,and basically identified the basic framework of Tanlu fault.The main fault can be divided into a ＂two-base folder of a cut＂ in Shandong Province and Suqian Lujiang Hidden fault,Lujiang Tongcheng fault.
