| 摘 要： | 文章以青海巴音山多金属矿化区为例,将高光谱数据处理方法运用于多光谱遥感数据中提取矿化蚀变信息.利用该区域的Landsat7 ETM遥感影像和标准光谱库中的特征蚀变矿物光谱为基本数据,借鉴已知矿物标准中的吸收谷特征,应用光谱特征匹配技术进行吸收谷谱区间和吸收谷深度对比,通过比较两者的相似性,达到提取蚀度矿物的目的,提取出许多有价值的似蚀变带遥感信息.结果证明了该方法在多光谱遥感矿化蚀变信息提取应用中的可行性,同时取得了较为满意的效果.

| Abstract: | Taking Bayinshan polymetallic mineralization area in Qinghai province as an example, processing method of hyper - spectrum remote sensing is used to discriminate and extract alteration information from multi - spectrum data. Using absorbed value feature of known mineral criterion for reference, utilizing Landsat 7 ETM remote images and features of altered mineral spectrum from USGS, valuable alteration mineralization information are extracted by comparison of spectrum similarity. The reeults have proved this new method is feasible and effective in extracting alteration information from multi - spectrum data. |
