摘要
以马尾松针叶野外高光谱测量数据和针叶灰分金属元素含量为基础,分析了铅锌矿区及对照区马尾松光谱变化、红边效应、植被指数及马尾松针叶金属元素含量特征。结果表明:矿区马尾松叶面在近红外区域反射率要低于背景区,马尾松红边位置发生了6～19 nm的蓝移,根据金属元素含量确定马尾松针叶对铅、锌、锰3种元素有较强的积累作用。
Based on the field hyperspectral measurement data and the content data of metal elements for the Pinus massoniana leaves, the spectral changes, red edge effects, vegetation index and the content of metal elements were analyzed between the Pb-Zn Deposit and the background area. The results showed that the reflectance of P. massoniana leaves in the near infrared region in Pb-Zn deposit was lower than that of the background area; the blue shift of red edge reached 6 - 19 urn. According to content of metal elements, the Pb, Zn and Mn were intensely accumulated by the leaves of P. massoniana.
