【摘要】 目前我国人工林蓄积量居世界首位,因此木材资源结构已由天然优质大径级材向低质小径木转变,低质小径木已成为我国工业用材的主体,研究以低等级人工林小径材开发用于建筑房屋的高强度木质结构材具有重要现实意义和广阔的发展前景。本文就国内外对小径木结构材研究和发展现状进行概述,阐述人工林小径材特性,并对其发展趋势作出预测。更多还原

【Abstract】 The amount of growing stock of plantation forests in China is in the first place over the world,which converts the structure of wood resource from natural high quality large diameter lumber into low quality small diameter and already became main body of the lumber in application of industry.It has operation significance and long term potential to study the project that uses the low grade natural small diameter lumber to develop high strength wood timbering used for house building.This paper summarized the current situation and research of small diameter timbering both here and abroad,brought up the characteristic of plantation forests small diameter lumber,and forecasted its development trend.更多还原
