【摘要】 研究结果表明，大别山区黄色杉木可以划分为松鳞（Ⅰ）、紧鳞（Ⅱ）和翘鳞（Ⅲ）３种类型，Ⅰ与Ⅱ、Ⅱ与Ⅲ型间物理力学性质差异极显著，而Ⅰ与Ⅲ间无显著差异；Ⅱ型杉木物理力学性质远大于其他两种类型，同时后期生长快，可培育大径级优质材，Ⅰ型杉木早期生长快，可培育小径级速生材，Ⅲ型杉木可用作特殊用材更多还原

【Abstract】 Yellow fir in Mt.Dabieshan was divided into loose scale (fir type Ⅰ),dense scale (fir type Ⅱ) and raise scale (fir type Ⅲ).The differences of physical characteristics between fir type Ⅰ and type Ⅱ,fir type Ⅱ and type Ⅲ were very significant while the difference between fir type Ⅰ and type Ⅲ was insignificant.The physical characteristics of fir type Ⅱ was much better than that of the other two fir types,and with faster mature growth which could produce large wood while fir type Ⅰ had faster juvenile growth which could produce smaller wood,fir type Ⅲ could produce wood of special purpose.更多还原
