摘　　要：木材识别对规范木材贸易市场、合理有效利用木材资源具有重要的实际意义。鉴于传统木材识别方法所面临的难题,探索新的识别方法已迫在眉睫。木材气味主要来源于植物的次生代谢产物。作为一种非常直观的化学信息,气味同样具有重要的分类学意义。气味指纹图谱技术是对样品挥发性成分进行检测,分析样品中具有特征性气味物质相关信息的检测方法,能够为木材树种识别提供快速、无损、精确的检测。文中重点对常见气味指纹图谱技术的基本原理以及在木材识别研究中的应用现状进行综述,旨在突破传统方法的局限性,为木材识别技术研究的进一步发展提供新的思路。虽然气味指纹图谱技术已经在木材及树种识别领域有所应用,但目前木材行业对木材气味特征的认识仍有不足,对木材气味的描述大多仍停留在嗅觉层面。同时由于气味形成机理较为复杂,木材气味的物质化学组成尚未明确。因此,迫切需要加强木材气味理论研究,利用科学的气味指纹图谱技术实现木材气味的整体分析,明确木材气味的化学物质组成,进一步挖掘气味特征在木材树种识别方面的应用价值。Wood identification is of great practical significance for regulating the timber trade market and promoting the rational and effective use of timber resources.In view of the difficulties that traditional wood identification methods are confronted with,it is urgent to explore new wood identification methods.Wood odor is mainly from the secondary metabolites of plants.As a very intuitive chemical information,odor is also of taxonomic importance.Odor fingerprint technology is a method to detect the volatile components of a sample and then analyze the information related to the characteristic odor substances,which can provide a fast,non-destructive and accurate wood identification.This paper reviews the basic principles of common odor fingerprint methods and their current application in wood identification research,aiming to break through the limitations of traditional methods and provide new ideas for the further research on wood identification technology.Although odor fingerprint techniques have been applied in the field of the identification of wood and tree species,the understanding of wood odor characteristics in the industry is still insufficient,and the description of wood odor mostly remains at the olfactory level.At the same time,the chemical composition of wood odor is not clear due to the complex mechanism of odor formation.Therefore,it is urgent to strengthen theoretical research on wood odor,so as to achieve the overall analysis of wood odor using odor fingerprint technology,clarify the material-chemical composition of wood odor,and further explore the potentials for applying odor characteristics to wood identification.
