摘　　要：为进一步探讨WorldView-2高分遥感数据在遥感调查中的应用效果,笔者选择青海卡而却卡地区进行图像信息增强及信息提取方法研究。在分析研究区内不同岩性的光谱曲线特征的基础上,针对遥感解译中目视解译效果不好、图像模糊和对比度不够等问题,提出一系列图像增强处理的方法,这些方法显著增强了岩性、构造的识别效果,可以更好地辅助高分遥感解译工作。同时,通过基于纹理和光谱信息的影像分类方法对大理岩、岩浆岩信息提取研究,可以较准确地圈定大理岩、岩浆岩岩性界线,并通过与现有地质矿产资料进行对比,该方法形成的岩性-构造解译图反映的岩性、构造等信息更加详细、丰富。WorldView-2 high resolution image was used in the remote sensing the application of Kaerqueka area by image enhancement and extraction.Based on the spectral curve characteristics of different lithology,a series of image enhancement processing method was used to solve the problems such as blur image,low contrast and bad visual interpretation result.This method not only enhanced the recognition effect of lithology,structure.In addition,a classification method based on texture and spectral information was used to extract the information of magmatic rock and marble,and accurately identify the lithologic boundary.Compared with the existing map of geology and mineral resources,the lithologic-structural interpretation result is more accurate and detail.
