生长在山东省招远市台上金矿区的灌木荆条（Vitex negundo var. heteropohylla (Franch.) Rehd.），其生长状况差于背景区，叶片的反射光谱特性发生变化，光谱特征参量LOR（实测叶绿素红光吸收波长）从背景区到金矿区向长波光方向位移，发生“红移”现象，而LPR（实测红界拐点波长）则向短波光方向位移，发生“蓝移”现象；LOR和LPR的变化与叶片的叶绿素含量密切相关。荆条反射光谱的“红移”和“蓝移”现象，可辅助进行植物光谱的遥感探矿。

At Taishang gold area in Zhaoyuan City, Shandong Province, the growth of Vitex negundo var. heteropohylla at gold area is more worse than that at background area. The spectral reflectance of red edge in leaves changes from background to gold area, the parameters of LOR and LPR shift towards longer (red shift) and shorter (blue shift) wavelengths respectively. The changes of LOR and LPR are relation to chlorophyll contents tightly.These can be considered to use in the mineral exploration of remote sensing.
