摘　　要：对福建武夷山木荚红豆树木材物理力学性质的测定和分析结果表明:福建武夷山木荚红豆树木材的气干密度为0.627g/cm3,属中等,较福建永安木荚红豆树木材的气干密度大;体积干缩系数为0.486,差异干缩为1.89,干缩性属中等,小于福建永安木荚红豆树;顺纹抗压强度和抗弯强度分别为51.93MPa和99.64MPa,综合强度为中等,大于福建永安木荚红豆树。该研究结果解决了木荚红豆树营林和木材利用上的一个基础性问题。The physical and mechanical properties of Ormosia xylocarpa wood from Wuyishan city of Fujian province were determined and analyzed in this paper. The results showed that Ormosia wood from Wuyishan city of Fujian province was middle with the density of 0. 627g/cm3, which was bigger than that from Yong＇an city of Fujian province. Shrinkage of Ormosia Wuyishan city of Fujian province belong to middle level, which volume shrinkage coefficient was O. 486, tangential shrinkage to radial shrinkage was 1.89. Both tangential shrinkage to radial shrinkage and volume shrinkage coefficient of Ormosia xylocarpa wood from Wuyishan than that from Yong＇an city of Fujian province. Compression strength city of Fujian province were less parallel to grain was 51.93Mpa, static bending was 99. 64Mpa of Ormosia xylocarpa wood from Wuyishan city of Fujian province. Comprehensive strength of Ormosia xylocarpa wood from Wuyishan city of Fujian province belong middle level, which was biggger than that from Yong＇an city of Fujian province. This research has solved a basic problem about the silvicuture and utilization of Ormosia xylocarpa.
