摘　　要：为增强杜仲全树开发的力度,提高木材利用价值,按照国家行业标准对杜仲木材的密度、顺纹抗压强度、硬度和握钉力4个力学指标进行了研究。结果表明：杜仲木材的密度范围在0.63～0.70 g/cm^3之间,平均密度为0.67 g/cm^3;顺纹抗压强度平均达47.72 N,显著高于黄榆木、文县杨;平均硬度达6215.50 N;握钉力为49.92 N/mm。杜仲木材具有较好的力学性能,是优良的商品木材原料,可广泛用于家具制造、木质工艺品、建筑等领域。To strengthen the tree development level and increase the utilization value of E.ulmoides, the timber mechanical property relating to the density, compressive strength parallel, hardness and nail holding ability were analyzed. The results showed that the density value was between 0.63 ～ 0.70 g/cm^3, the average is 0.668 g/cm^3; the average value of compressive strength parallel was reached to 47.72 N; the average value of hardness was 6 215.50 N; and the average value of nail holding power was 49.92 N/mm. It is suggested that Eucommia timber have the excellent mechanical property and good wood material. Eucommia timber will have a very bright application among furniture industry, woody handicraft articles and construction materials, etc.
