摘　　要：木材资源的多元化利用符合可持续发展国家战略方针。但木材在使用过程中会由于内部或外界因素产生变色,造成木材性能劣化,直接影响木材及其制品的质量。因此,研究木材变色机理以缓解木材缺陷具有现实意义。目前已有大量研究集中于木材随环境因子的变色规律,但仍存在环境条件考虑单一、化学结构变化规律不明确等问题。文中将变色木材的主体分为活立木和木材加工产品2类,分别对其变色的内因和外因进行总结;分析目前研究中存在的问题和未来研究方向,以期通过总结已知环境因子对木材变色的作用,服务于各因子协同作用下木材变色结果的研究,为减少木材变色缺陷和定向调控木材颜色提供研究思路,并为提高木材综合性能、拓展木材及其制品的应用范围提供参考。Diversified utilization of wood resources conforms to the national strategic policy of sustainable development.During the use of wood,discoloration occurs due to internal or external factors,resulting in deterioration of wood properties and leading to the poor quality.Therefore,it is of practical significance to study the mechanism of wood discoloration for alleviating wood defects.At present,many studies have focused on the effect of environmental factors on wood discoloration,but the problems have not been solved,such as only considering a few environmental factors and the unclear change pattern of chemical structure.In this paper,the wood discoloration is studied for wood in living trees and wood products,respectively,with the aim to summarize the internal and external reasons behind the discoloration.It is expected that the summary of known environment factors'role in wood discoloration through analyzing the problems in the current research and the future direction will facilitate the research on wood discoloration under the synergistic effect of all factors.This study would provide the ideas for the research on reducing the defect of wood discoloration and improving the directional regulation of wood color,and provide references for enhancing comprehensive performance of wood and expanding the application of wood and wood products.
