对山东招远金矿区进行了赤松针叶反射光谱红边 3个特征波长参量λ_pr、λ_pg、λ_og 随季节变化规律的研究,结果表明,矿区相对于背景区,3个特征波长参量在全年内均呈现不同程度的“蓝移”,当年生叶和去年生叶分别以秋季和春季“蓝移”最大,说明春季和秋季是高光谱分辨率遥感探测赤松林下金属矿藏的最好季节。

This paper discusses the seasonal characteristics of three characteristic wavelengths of λ_pr,λ_pg,λ_og of Red-Edge reflectance for the Korean Pine leaves in gold mine area of Zhaoyuan City,Shandong Province The results indicate that the three characteristic wavelengths in gold mine area show annuall blue shifts in varying degrees against backgound area and the blue shifts are the biggest in fall for the first-year leaves and in spring for the second-year leaves,therefore,spring and autumn are the best season for detecting metal mineral under Korean Pine Forests using remote sensing method.
