摘要
文章基于野外的实测光谱数据,对岩石、土壤和植被的光谱反射特征以及它们在统计空间的分布关系进行分析研究,总结中等植被覆盖的矿物蚀变区典型地物的光谱反射特征以及不同地物在光谱空间的分布规律,为矿物的遥感蚀变信息提取提供一定的科学依据,有利于改进蚀变信息提取的方法。
Based on the field spectral data,the article analyses the spectral reflectance characteristics of rocks,soil and vegetation,as well as their distribution correlation in statistics space.The article summarizes spectral reflectance characteristics of typical ground object in mineral alteration zone of medium vegetation overlaid and spectral space distribution pattern of different ground objects.This provides scientific evidence for information extraction of mineral alteration remote sensing.It is also useful in improving the extraction method of alteration information.
