摘要
对不同立地条件拟赤杨人工林木材材性进行测定和比较分析,结果表明:立地条件与拟赤杨人工林木材材性存在密切的关系.拟赤杨人工林木材密度、干缩系数、差异干缩和除冲击韧性以外的其它力学强度指标均随着立地级的提高而减小,木材冲击韧性随着立地级的提高而增大,拟赤杨人工林木材密度、干缩性和力学强度的波动性随着立地级的提高而减小.经差异显著性T检验表明:立地级对拟赤杨人工林木材密度、差异干缩和大部分力学强度指标影响极显著或显著.
Wood properties of Alniphyllum fortunei plantation in different sites were determined and analyzed comparatively. The results showed that there were close relationships between siets and wood properties of Alniphyllum fortunei plantation . The density , shrinkage coefficient , ratio of tangential shrinkage to radial shrinkage and most mechanical strength indexes except impact toughness decreased as sites increase while impact toughness increased as sites increase . Furthermore , dispersion of the density , shrinkage and mechanical strength for Alniphyllum fortunei wood from plantation decreased as sites increase. Different significant T test showed that sites affected extremely significantly or significantly on density , ratio of tangential shrinkage to radial shrinkage and most mechanical strength indexes of Alniphyllum fortunei wood from plantation.
