摘　　要：选择多种方法对浅覆盖地区进行地层、构造信息提取研究,以SPOT5和ASTER为数据源,以内蒙古锡林浩特市毛登地区为例.采用PCA分析法对ASTER数据进行处理,确定不同时代地质体的分布特征;配合SPOT5图像进行目视解译,对其边界进行划定,并对该地区的线性构造、环状构造进行解译.研究结果表明:(1)将短波红外和热红外波段进行PCA分析,可对不同地质体的分布进行初步划分;配合目视解译,可较为准确的确定其界线;(2)利用SPOT5数据对构造进行解译具有很好的效果;从而为1:5万区域地质调查工作提供了具有参考价值的信息.A serious of methods were selected to extract the stratum and structures by using the SPOT5 and ASTRE data in the Maodeng area of Inner Mongolia. PCA analysis using ASTER remote sensing data determined the work area features of different geological body image. The visual interpretation by using SPOT5 data delineated the geological boundary and lineaments in the region, the annular structure to understand translation. Results showed that： 1） Using PCA analysis in the shortwave infrared and thermal infrared, it can divide the area features of different geological body image by visual interpretation and confirm the boundary by rule and line.2）It has a good effect in the structures interpretation by using the SPOT5; It provided valuable information to 1：50000 regional geological survey.
