叶片-冠层尺度的毛竹林分光谱特征
Spectral Scale Differences between Leaf and Canopy of Spectral Characteristics of Phyllostachys pubescens Forest
摘要
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.关键词
