摘 要随着现代科学技术的快速进步推动着航天技术的发展， 使遥感技术进入了一个崭新的时代，能够多方位的对地面进行观测。新型传感器的不断进步改变了过去传感器较为单一的状况，现在已涌现出多种类型的传感器。这些传感器在时间分辨率、空间分辨率、光谱分辨率和辐射分辨率四个方面都取得了较大的改进，人们可以通过这些传感器来获得满足他们不同需要的遥感影像。利用遥感影像提取地质信息是遥感技术在科学研究领域里得以应用的一个重要体现[1]，从遥感图像我们常可以直接或间接地得到一些地表特征信息。由于地物的某些特征在高空间分辨率遥感影像上往往表现地较为清楚， 因此在人工目视解译方面具有较好的优势。本论文是对国产的高分一号影像在地质信息提取中的应用进行研究， 以山西省晋城市沁水县柿庄镇南为研究区，在遥感数据处理软件（包括ENVI 5.1、ERDAS IMAGINE 9.2）的支持下，对原始的遥感影像数据预处理，采用多波段组合分析、 直方图匹配和彩色空间变换等图像增强的方法使遥感影像信息表现地更加突出。利用监督分类的方法，对遥感影像进行岩性识别，并结合目视解译，提取出该区域的岩性信息，并利用ArcGIS10.2 软件对研究区岩性信息解译结果进行制图。37425

Abstract
In the recent year, with the continuous improvement of sensortechnology, aerospace technology and data communication technologyplatform, remote sensing technology has entered a new stage which isdynamic, rapid, accurate, more means to provide earth observation data.The situation of single sensor in the past has been changed by theconstantly emerging of new type of sensors including a variety of spatialresolution, time resolution and spectrum resolution of remote sensingimage sensor.The extraction of geological information from remote sensing image isan important research field of remote sensing technology, and we candirectly or indirectly obtain some surface features information. Highspatial resolution image has a good visual interpretation, because of itsfeatures clear characteristics. The study area is located in Qin ShuiCounty, which belongs to Shan Xi Province. This paper studies theapplication of homemade GF-1 image on the extraction of geologicalinformation of this region, using the method of supervised classificationand visual interpretation.This paper by ENVI5.1, ERDAS IMAGINE9.2 software for dataprocessing platform, firstly do a series of remote sensing datapreprocessing, and then enhance the effect of image by multibandcombination analysis, histogram matching and so on. Finally, thegeological information interpretation map in the study area will be madeout by ArcGIS10.2 software mapping function.
Key Words: GF-1; Lithology information extraction; Imageenhancement; Supervised classification.
