摘要:
 通过测定毛竹林的林分光谱数据与相应的叶绿素含量，选用原始光谱反射率、导数变换光谱与“三边”参数3种光谱形式，研究不同形式的光谱信息与相应叶绿素含量的相关关系，揭示毛竹林分光谱特征在叶片—冠层尺度的差异。结果表明，叶片尺度上，原始光谱反射率对叶绿素的敏感波段在可见光区域的543~580 nm，导数光谱的敏感区域在532~543 nm、599~607 nm以及728~736 nm，“三边”参数的敏感参数为黄边面积参数（SDy）；冠层尺度上，原始光谱在可见光区域及近红外区域对叶绿素的响应程度未达到显著性水平，导数光谱的敏感响应波段在近红外区域的816~819 nm，“三边”参数中各参数与叶绿素含量均没有良好的相关性。叶片—冠层尺度上，某些波段的导数光谱比原始光谱对叶绿素具有更好的响应，并且“三边”参数的黄边区域参数对叶绿素的敏感性均高于其他参数，但冠层尺度与叶片尺度光谱对叶绿素的敏感区间不存在重叠。
Abstract:
 The correlation relationship was analyzed between chlorophyll content and spectral information of different patterns (original spectral reflectivity,derivative transformation spectral reflectance and trilateral parameters) to reveal spectral scale differences in spectral characteristics between leaf and canopy of Phyllostachys pubescens forest by determining spectral data of P.pubescens stands and its chlorophyll content.The results showed that in the leaf scale,the sensitive bands of chlorophyll were 543-580 nm at the visible range of the original spectrum,532-543 nm,599-607 nm and 728-736 nm at the first derivative spectrum; and the sensitive parameter of trilateral parameters was yellow edge region (SDy).In the canopy scale,The correlationship between original spectrum in the visible and near-infrared regions and chlorophyll content did not reach significant levels; the sensitive bands of the first derivative spectrum in near-infrared regions was 816-819 nm,and there was no good correlation between trilateral parameters with chlorophyll content.In the leaf and canopy scale,the first derivative spectrum of some bands responded better than the original spectrum,and SDy of trilateral parameters was better sensitive to chlorophyll content than the other parameters,while there was no overlapping sensitive areas between the leaf and canopy scale.
