摘要

．本研究的重点是利用近红外(NIR)光谱来解决马达加斯加黄檀树种木材鉴定缺乏工具和技能的问题。在马达加斯加北部和西部地区采集了4种黄檀(D. abrahamii、D. chlorocarpa、D. greveana和D. pervillei)的2组共41个木块和41个木芯样本。采用便携式VIAVI MicroNIR 1700光谱仪对含水率为12%的木材进行边材和心材近红外光谱测量。利用偏最小二乘判别分析(PLSDA)建立了两种样型边材和心材的4个判别模型。

Use of a Portable Near Infrared Spectrometer for Wood Identification of Four Dalbergia Species from Madagascar

. This study focused on the use of Near InfraRed (NIR) Spectroscopy to address the lack of tools and skills for wood identi ﬁ cation of Dalbergia species from Madagascar. Two sample sets of 41 wood blocks and 41 wood cores belonging to four Dalbergia species ( D. abrahamii , D. chlorocarpa , D. greveana , and D. pervillei ) were collected in the northern and western regions of Madagascar. Sapwood and heartwood NIR spectra were measured on wood at 12% moisture content by using a portable VIAVI MicroNIR 1700 spectrometer. Four discrimination models corresponding to sapwood and heartwood of the two sample forms were developed using Partial Least Square Discriminant Analysis (PLSDA).
