| 摘 要： | 根据研究区蚀变岩在ETM图像上的光谱特征,利用比值增强、主成分分析及比值增强后主成分分析等方法,对内蒙古乌拉山地区蚀变岩信息进行增强,进而采用均值加标准差与最优密度分割相结合的方法对蚀变信息进行提取和分析。通过多层次的筛选和评估,划出真异常区,制作遥感异常图。

| Abstract: | According to the spectral characteristics of the altered rocks in the ETM image of the study area,the authors enhanced the altered rock information along Wulashan region in Inner Mongolia through using the value enhancement,principal component analysis and principal component analysis after enhanced,and made extractions and analyses on the alteration information by using the methods of mean plus standard deviation and in combination with the optimistic density separation.Through multi-level selection and as... |
