为进一步发掘麻竹材加工利用潜力，通过对不同竹龄、不同部位麻竹材的气干密度、力学性质、燃烧性能及其相关关系进行分析。结果 表明：（ 1）竹龄对麻竹材气干密度、顺纹抗压强度、抗弯强度、抗弯弹性模量、点燃时间、释热速率、质量损失率、释烟总量及 60、180、300 s比消光面积均有显著影响，而对抗拉强度无显著影响；（ 2）竹材部位对气干密度、顺纹抗拉强度、抗弯强度有显著影响，而对顺纹抗压强度、抗弯弹性模量无显著影响；（ 3）麻竹材顺纹抗拉强度：顺纹抗压强度：抗弯强度：抗弯弹性模量 =3.06 ∶ 1.00 ∶ 2.63 ∶ 164.28；（4）麻竹材气干密度与顺纹抗压强度、抗弯强度、抗弯弹性模量、点燃时间、释烟总量、 60 s比消光面积和 300 s比消光面积呈显著正相关，且相关系数达到 0.899～ 0.958。 4 a生麻竹材的气干密度、力学性质及燃烧性能等指标渐趋基本稳定，利用简单易测的麻竹材气干密度能较准确预测评价麻竹材部分力学性质与燃烧性能。
In order to further explore the potential value of processing of Dendrocalamus latiflorus Munro timber, the air-dried density, mechanical property and combustion performance in different ages and positions of D. latiflorus timber were comparative analyzed as well as the relationship between each other. The results showed that: (1) the age of D. Latiflorus had a significant affect on D. Latiflorus timber’s air-dried density, compressive strength parallel to grain, bending strength, bending elastic modulus, ignition time, heat release rate, mass loss rate, total smoke release, and 60-second, 180-second, 300-second specific extinction area, but not on tensile strength parallel to grain. (2)The position of D. Latiflorus timber also had a significant influence on D. Latiflorus timber’s air-dried density, tensile strength parallel to grain, and bending strength, but not on the compressive strength parallel to grain, and bending elastic modulus. (3) Tensile strength: compressive strength: bending strength: bending elastic modulus= 3.06 ∶ 1.00 ∶ 2.63 ∶ 164.28. (4)The air-dried density were significantly positively correlated with compressive strength, bending strength, bending elastic modulus, ignition time, total smoke release, 60-second specific extinction area, 300-second specific extinction area, and correlation coefficients range from 0.899 to 0.958. The air-dry density, mechanical property and combustion performance of 4-year-old D. Latiflorus timber tend to be basically stable, and it was possible to accurately predict and evaluate parts of the mechanical property and combustion performance of D. Latiflorus timber by using its air-dry density.
