  • Hyperspectral technology has high precision in the fine detection of ground objects, and can realize the extraction of weak information. In this paper, hyperspectral remote sensing technology was used to study the correlation between heavy metals, copper and lead, and the spectral stress of covered vegetation in the high-vegetation area of Fanshan, Fujian. By comparing and analyzing the spectral characteristics of typical vegetation in mining areas and non-mineral areas, this paper indicates that the typical vegetation in the mining area is subjected to heavy metal element stress to different degrees, causing the spectrum to mutate. Based on the analysis results, the paper established the mathematical model of correlation between heavy metal and vegetation spectral stress based on vegetation geochemical data, and proposes the correlation between heavy metal and vegetation cover stress. According to the model, the spatial distribution of metal elements can be obtained, and finally the application of high-spectral remote sensing in geological prospecting in high vegetation coverage areas is overcome.
