高光谱遥感技术在地质领域中的应用

THE APPLICATION OF THE HYPERSPECTRAL IMAGING TECHNIQUE TO GEOLOGICAL INVESTIGATION

近年来,高光谱应用技术在地质领域得到了深入的应用与发展,不仅深化了地质学的基础研究,也推动着遥感地质填图从岩性填图向矿物填图的飞跃,推进了高光谱遥感技术在成矿预测、地质成生环境成因信息探测、植被地化信息与理化信息提取以及矿山环境调查等应用的不断深入。本文围绕高光谱技术的特点,并结合作者近年来的工作实践,论述了高光谱技术在上述领域的实际应用情况与应用效果。

The hyperspectral imaging technique has been used widely in geosciences and geological investigation. Based on the authors＇ practice, this paper mainly deals with the application of hyperspectral imaging data to such fields as mineral mapping, metallogenic prognosis, vegetation geochemical exploration and physiological extraction, and mine environment analysis. The results obtained can not only help the basic geological study but also promote the remote sensing mapping from lithological mapping to mineral mapping. It is obvious that the hyperspectral imaging technique will play an increasingly important role in geological investigation in future.
