| 摘 要： | 介绍了对应分析方法及其在成功提取哈达门沟金矿含金蚀变岩带信息的应用实例。该方法对变量和样品统一分析,将原始波段的大部分信息集中在几个互不相关的特征波段中,其中几类主要的地物在这些波段区别明显,从而可利用少数几个波段表征所要信息,有效地减少了数据的冗余,实现含金蚀变岩带信息的快速提取。

| Abstract: | The Correspondence Analysis Method and a successful example of its application for extraction the auriferous alteration zones in the Hadamengou gold ore deposit have been presented in the paper. The Correspondence Analysis Method which characterized by corresponding variables with samples summaries most information in the primary bands into several feature bands having no mutual relatives, and among them the major surface features can be obviously distinguished. Therefore, the desired feature information can be demonstrated by few bands, and the enormous data volumes are minimized. With this method the auriferous alteration zones can be extracted quickly. |
