摘要: 基于背景多层次分离的遥感矿化蚀变信息提取模型,以地物的波谱特征和遥感技术的物理机制为基础,以“矿化蚀变岩波谱特征分析—视反射率图像计算—“背景”多层次分离—蚀变信息增强—蚀变信息提取”为技术流程,能快速、准确地提取矿化蚀变信息。以新疆焉耆县哈都虎拉山一带为研究区,以最新的Landsat8\|OLI多光谱数据为数据源,将该模型用于提取研究区的黄钾铁矾蚀变岩石信息,共提取出80余处黄钾铁矾蚀变岩石出露点,其中有两处黄钾铁矾蚀变岩石集中分布区,为研究区的找矿工作提供了重要线索。 关键词: 视反射率图像;  掩膜;  比值增强;  黄钾铁矾;  Landsat8     Abstract: This paper presents a model of the alteration mineral mapping base on multi\|level separate background.The understructure of this model is the physical mechanism of spectral features and remote sensing technology.The procedure of this model is “analysis of spectral characteristics of mineralization and alteration rock\|\|calculation of apparent reflectance image\|\|‘background’ multi\|level separation\|\|alteration information enhancement\|\|alteration mineral mapping”.This model can quickly,accurately extract alteration information.This paper chooses Mount Hadu Hula in Yanqi County,Xinjiang,as study area and the new Landsat8\|OLI multi spectral data is as the data source.Then the model is used to extract jarosite altered rocks information in this study area and it has extracted more than 80 jarosite altered rocks dew points.In these points,there are two concentrated region of jarosite altered rocks,which provides important clues of prospecting work for the study area.
