摘　　要：采用单波段灰度拉伸、彩色合成及与高分辨率遥感影像数据融合、波段比值、主成份分析等遥感数据处理方法,对原始ETM+影像数据进行处理。根据影像处理结果,运用目视解译方法,并遵循由已知到未知、由宏观到微观、由简单到复杂、取其长避其短的解译原则,参考该地区1∶5万与1∶20万地质图,对甘其毛道地区出露的岩石地层进行了全面的解译。通过解译,划分岩石地层影像单位15个,对其建立遥感解译标志。经野外验证,所划分的岩石地层单位基本与实际相吻合。本文详细介绍甘其毛道地区ETM+卫片数字图像处理的地层影像解译方法、解译标志和解译成果。We use single band gray stretching,colour composite,high resolution remote sensing image merge,band ratio,Principal component analysisand any other remote sensing image mathods to deal with the original ETM＋ image data.According to the treatment result,we use Visual interpreting and follow some interpreting principles.Such as：from know to unknow,from macroscopic to microcosmic,from simple to complex and take advantage to avoid weakness and refer the 1：50000 and 1：200000 geological map to interpret the exposed lithostratigraphy of the Gan Qi Mao Dao area.Then divide 15 Lithostratigraphic units and established the remote sensing interpretational key.The field test shows that these lithostratigraphic units are basically cionciding with the actual.This article detailed intraduce the achievement,the method and the symbol of the interpretation of strata image of the Gan Qi Mao Dao area.Meanwhile,the interpretation is disposed by landsat ETM＋ imagine.
