| 摘 要： | 蚀变信息的研究一般利用ETM+遥感数据,通过数字图像来处理的.文中利用landsat7 ETM+卫星影像数据,采用主成分分析、比值法,对内蒙古巴彦淖尔地区进行铁化蚀变信息的提取.研究表明,由于受大面积第四系被氧化铁污染的影响.主成分分析提取铁的氧化物类蚀变异常的效果并不理想;而比值法抑制了大面积分布的第四系受氧化铁污染的影响.分析铁化蚀变异常显示效果较为理想,并结合一些遥感图像地质解译,更有利于应用遥感矿化蚀变异常划分找矿远景区.为进一步综合找矿预测提供了依据.

| Abstract: | The study of alteration information generally use ETM + remote sensing data,through the digital image to the deal.In this paper,using landsat7 ETM + satellite image data,principal component analyses and ratio technique are main ways for extracting alteration information in bayanchuoer area,Inner Mongolia.Study shows that due to a large area of Quaternary by iron oxide pollution,the results of principal component analysis for extracting of iron oxide alteration of abnormal were not very satisfactory ;while t... |
