| 摘 要： | 研究了３０年左右生红皮云杉人工林木材的主要物理力学性质，并对人工林与天然林木材基本密度的径向变异及主要材性差异进行了比较。结果为：（１）由于红皮云杉３５年生人工林尚处于龄期，其木材的主要物理力学性能均低，其中基本密度０．３１８ｇ／ｃｍ＾３，顺纹抗压强度２９．２１ＭＰａ，抗弯强度５６．６３ＭＰａ，弯曲弹性模量７．７８８ＧＰａ。（２）人工林木材的密度干缩率以及顺压强度、抗弯强度均略低于天然林，而吸水率

| Abstract: | This paper deals with the wood physical and mechanical properties of 30 years old korean spruce plantations. The differences between wood properties and radial variation of wood specific gravity from plantations and natural stands are also studied. The results are as follows:(1) 35 years old korean spruce plantations are still juvenile and their properties are low.The values of basic density, copressive strength parallel to grain, MOR (modulus of rapture )and MOE(modulus of elasticity) are respectively 0.318g/cm 3, 29.31MPa,56.63MPa and 7.788GPa. (2)There are not significant differences between plantations and natural stands in the wood properties. |
