摘　　要：对成熟人工林的油杉(Keteleeria fortunei)、杉木(Cunninghamia lanceolata)和马尾松(Pinus massoniana)木材的物理与力学性质进行测定与比较。结果表明,油杉木材的气干湿胀性、抗弯强度、顺纹抗压强度和径面硬度最优,杉木木材的全干干缩率、气干干缩率和吸水后湿胀性最优,马尾松木材的气干密度、全干密度、端面硬度和弦面硬度最优。木材密度的表现为马尾松>油杉>杉木;木材稳定性的表现为杉木>油杉>马尾松;木材力学的表现为油杉>马尾松>杉木。Physical and mechanical properties of woods of Keteleeria fortunei and Cunninghamia lanceolata and Pinus massoniana plantations in mature age were determined and compared.Results showed that air-dry swelling property,modulus of rupture,compressive strength for parallel to grain direction and radial section hardness of K.fortunei wood were best.Oven-dry shrinkage,air-dry shrinkage and swelling property after absorbing water of C.lanceolata wood were the best.Air-dry density,oven-dry density,tangential surface hardness and radial surface hardness of P.massoniana wood were best.Order of wood density was P.massoniana>K.fortunei>C.lanceolata;order of wood stability was C.lanceolata>K.fortunei>P.massoniana;and order of wood mechanics was K.fortunei>P.massoniana>C.lanceolata.
