摘　　要：卫星影像上的线性信息是地表一些线性构造的映像,这些线性构造与矿产形成分布有着密切的关系。对东天山图屋-延东一区TM数据利用ERDAS IMAGE 8.7图像处理软件进行了图像增强处理,通过借鉴前人机助线性体研究的方法和思路,利用M atlab7.0软件开发平台工具,采用Hough变换等技术手段在该区进行线性构造信息提取,并将提取结果与人工解译结果进行对比和评价,探讨了该区线性构造信息提取的途径,为研究区今后的找矿和工作部署工作提供了参考。Some linear information on satellite images is the reflections of the linear structures of the earth surface, and some of these lineaments are closely related to the mineral distribution. The enhancement processing of TM remote sensing image data of Tuwu- Yandong belt in East Tianshan Mountain using ERDAS IMAGE8.7 image processing software was carried out. The in-formation of linear structures of Tuwu - Yandong belt was extracted using Hough transformation and based on methods and thinking established by other researchers and Matlab7.0 platform. Meanwhile, the extracted results were compared with ones obtained by manual extraction, the way to extract the information of linear structures in this area was discussed. This work provided references for the further prospecting and the disposition of investigation in the study area.
