摘　　要：重点介绍基于蚀变矿物光谱特征分析,选用相应的光谱波段和图像处理技术,增强和提取巴什布拉克铀矿区蚀变信息;阐述了遥感影像解译效果,分析了铀矿区蚀变与矿化的关系。研究表明:应用遥感信息增强和提取技术可以有效地获取巴什布拉克铀矿区的赤铁矿化和黏土化等蚀变信息,而矿化严格控制在上述蚀变地层中。该认识对研究区的铀矿普查勘探具有指导意义。The paper recommends enhancement and extraction results of alteration information in Bashibulake uranium ore-district. Methods to select spectral bands and process image so as to enhance and extract alteration information are firstly introduced based on spectral feature analysis of alteration minerals. Then, interpretation results of processed image are presented. The research has indicated that good results can be obtained using image enhancement and information extraction technique. The alteration information extraction is useful for uranium prospecting and exploration in the area since uranium mineralization has close relationship with alteration.
