    摘要:

    以無損檢測為前提,采用激光為激發(fā)光源,對楊樹活體葉片進(jìn)行熒光光譜采集,對采集到的光譜數(shù)據(jù)進(jìn)行處理分析得到水分利用效率的熒光光譜敏感波段,建立基于葉片溫度修正下的植物水分利用效率與熒光光譜的數(shù)學(xué)回歸模型,模型的復(fù)相關(guān)系數(shù)R2=0.975。并對建立的數(shù)學(xué)回歸模型進(jìn)行效果檢驗,相關(guān)系數(shù)r=0.8746,模型的檢測效果較好。

    Abstract:

    Based on non-destructive detection, the fluorescence spectrum of living leaves of poplar was collected by laser as excitation light source. Sensitive fluorescence spectrum band of water use efficiency was arrived through analyzing spectrum data. A model depending on the modification of leaves temperature was established. The functional relation between water use efficiency and fluorescence spectrum was described and the multiple correlation coefficients R2 were 0.975. The correlation coefficient r between calculated values and measured values was 0.8746 by verification test.
