当代木材科学的发展趋势

文章从木材的解剖、化学、物理、力学、干燥、防腐等领域,阐述了现代木材科学正向纵向深入和横向交叉的方向发展。木材科学正面临着因环境、木制品性能和木材优化加工等社会重大问题的挑战。国际间共享木材科研成果、共享设备的呼声日益高涨,研究的合作化和国际化正成为现代木材科学发展的重要途径。

The Development Trend of Modern Wood Science

Now the development of wood science in the world is characterized by in-depth and interdisciplinary research.In wood anatomy,researches on wood structure,ultrastruc-ture,woody plant classification and phylogeny are conducted.In wood physics researches on the electric,thermal,acoustic and optic aspects and its relation with fluids are conducted.In wood mechanics,researches on solid wood,wood-based panels,and laminated wood products have been conducted.In wood chemistry supported by new technology,new re-sults have been obtained from researches on cellulose structure,preparation of new deriva-tives,semicellulose and lignin.The wood drying technology becomes more and more perfectby high temperature drying,and use of solar energy and vaccum.Preservatives become di-versified in variety Protective agents tend to be high efficient,low toxic and even nontoxic.As more strict requirements are made by environmental protectio,now the wood science isfacing the challenges to increase the yield of plantations,and the inevitable optimized proce-ssing of wood in order to improve the performance of wood products.It is imperative tostreng then the researches on directional culture of wood in plantations and the optimized processing and utilization so that the social demand for wood and forest products can be met,the comprehensive and sustained management and development of wood resources can be re-alized,and the economic utilization of natural resources and the environmental protection can be well coordinated.In the international community,more opinions are voiced for common use of equipment and results from wood scientific researches,and the modern wood science is tending to become cooperative and international.
