铜胁迫下植被光谱变化规律研究

Study on Spectral Change of Vegetation under Cu Stress

通过实验的方法，对不程度铜胁迫下玉米光谱变化规律进行了研究。研究表明，随着铜胁迫程度的加剧，在可见光及其附近（350～800nm）植物光谱反射率曲线不断抬升．“绿峰”明显上升，“红谷”的深度明显变浅，“红谷”和“绿峰”之间的坡度变缓“红边”有规律地“蓝移”。

By the experiment,the spectral changes of corn under different copper stress were investigated. The investigation showed that with the increasing degree of copper - stress, the spectral reflectance curve rises gradually within the range of visi- ble spectra and its adjacent area （ 350 - 800 nm ） , the＂ green pick＂ uplifts obviously, the depth of ＂red valley＂ becomes more and more shallow, the slope between the＂ red valley＂ and the＂ green pick＂ gets flatter,＂ red edge＂ shifts to blue band.
