摘　　要：植被遮盖增加了地质勘探和资源管理的复杂性。高光谱遥感技术的发展为克服这一挑战提供了新途径,对植被覆盖区域的岩矿蚀变信息提取逐渐引起广泛关注。本文探讨了基于Hyperion高光谱数据的植被覆盖区域岩矿蚀变信息提取方法,具体研究目标包括高光谱数据的预处理、波谱反射率的反演以及野外测试波谱曲线的结合,以像元波谱匹配技术提取特定岩矿蚀变信息。通过研究,旨在为植被覆盖区域岩矿蚀变信息的提取提供新的思路和方法,从而为地质勘探和资源管理等领域的决策提供更准确的数据支持。Vegetation cover adds complexity to geological exploration and resource management,limiting the application of traditional remote sensing techniques.The development of hyperspectral remote sensing technology provides a new approach to overcome this challenge,gradually attracting widespread attention for extracting rock and mineral alteration information in vegetated areas.This paper aims to explore a method for extracting rock and mineral alteration information in vegetated areas based on Hyperion hyperspectral data.Specific research objectives include data preprocessing,spectral reflectance inversion,and the integration of field-tested spectral curves,using pixel spectral matching techniques for extracting specific rock and mineral alteration information.Through this study,we aim to provide new insights and methods for the extraction of rock and mineral alteration information in vegetated areas,thus offering more accurate data support for decision-making in fields such as geological exploration and resource management.
