摘要
在遥感找矿中,矿化蚀变信息的提取是重要的工作内容之一。以TM/ETM+为数据源进行矿化蚀变信息的提取,经历了一个由简单到综合的发展历程。为更好地开展蚀变信息的提取工作,本文在总结前人研究的基础上,将各种蚀变信息的提取方法归结为两个模式,即"经验模式"和"准定量模式",并对两种模式下的各种方法结合实例进行了介绍,最后对两种模式的关系作了初步的探讨。
In mineral resources prospecting with remote sensing, mineralization-alteration information extraction is one of the crucial steps. Technology of information extraction with TM/ETM＋ as data sources has gone through an experience from unitary development to comprehensive one. Based on prior studies, various methods of information extraction are summarized, in this research, under two models.. ＂experiential model＂ and ＂quasi-quantitative model＂. And those methods are introduced with specific cases. Additionally, the relationship is explored between the two models in this paper.
