摘　　要：通过对格木木材物理力学性质进行测定和分析,结果表明:格木木材密度大、变形大,其气干密度为0.857 g·cm-3,基本密度为0.746 g·cm-3,体积干缩系数为0.615,顺纹抗压强度为67.59 MPa,抗弯强度为141.82 MPa,综合强度为209.41 MPa,属于高。该研究结果解决了格木营林和木材利用上的一个基础性问题。The wood physical and mechanical properties of Erythrophleum fordii were determined and analyzed in this study. The results showed the wood of Erythrophleum fordii was of high density and big deformation. The air-dry density was 0.857 g·cm^-3, the basic density was 0. 746 g·cm^-3 and the shrinkage coefficient of volume was 0. 615. The compression strength parallel to grain was 67.59 MPa, the bending strength parallel to grain is 141.82 MPa and the composite strength was 209.41 MPa. This study solved a basic problem about the plantation and utility of Erythrophleum fordii.
