| 摘 要： | 为了探讨毛竹出笋后快速生长期茎秆色素含量与反射光谱特性间的相互关系,测定了毛竹茎秆在快速生长期内的色素含量与反射光谱参数,并对两者进行了相关性分析.结果表明:(1)在毛竹出笋后快速生长期内,随着茎秆不断生长,叶绿素a、叶绿素b和类胡萝卜素含量也随之增加,在60 d时含量最高.(2)反射光谱参数GNDVI、PSDNa、PSSDa、PSSDb、PSDNb、mND705、mSR705、CRI1、ARI1和PRI等均随着茎秆生长而增加,NPCI、SIPI和RGI则随生长而降低；Sred随着茎秆生长基本呈现出不断增大的趋势.各参数在20 d到30 d时的变化均达到极显著水平(P＜0.01).(3)GNDVI、PSSRa、PSSRb、PSSRc、PSNDa、PSNDb、PSNDc、NPCI、mSR705、mND705、CRI2、PRI、Dλred和λred等反射光谱参数与叶绿素a、叶绿素b和类胡萝卜素含量之间的相关性均达到极显著水平(P＜0.01),其中PSSRb、mSR705、CRI2、PRI、ARI1和ARI2与叶绿素a、叶绿素b和类胡萝卜素含量之间的相关性高于或接近0.9,说明毛竹出笋后快速生长期反射光谱特征及其参数可用来估算叶绿素和类胡萝卜素含量,并为利用反射光谱监测其生长趋势提供了可能. |
