摘要
以马尾松针叶野外高光谱测量数据和叶微量元素含量为基础,分析了铅锌矿区和对照区马尾松针叶反射光谱特征和红边效应,对蓝移偏移量和叶绿素归一化指数与叶主要微量元素含量的相关性做了分析.结果表明：矿区马尾松针叶在近红外区域反射率要低于对照区,马尾松针叶红边位置发生了6~19 nm的蓝移,马尾松针叶红边蓝移偏移量与铅、锌两种元素含量成正相关,叶绿素归一化指数与铅、锌、锰3种元素含量成负相关.
The reflectance spectrum of Pinus Massoniana is measured,the contents of trace elements in the leaves are examined,and the correlations of both the Blue shift and ChlNDI with the content of trace elements are analyzed.The results indicate that the reflectance of Pinus Massoniana leaves in near infrared region in Pb-Zn deposit was lower than that in the background area,the blue shift of red edge reaches 6-19 nm,the blue shift is positively correlated with the contents of Pb and Zn,and there is a negative correlation between ChlNDI and the contents of Pb,Zn and Mn.
