| 摘 要： | 本文测定了长岭岗林场不同立地条件下23a生柳杉人工林的木材干缩性能指标，进行了不同立地条件下各指标的差异性的F检验。结果表明：在不同立地条件下，柳杉全干径向干缩率和全干体积干缩率存在显著差异(0=0．05)，立地对全干弦向干缩率、差异干缩以及气干干缩指标影响不显著；土层较厚，柳杉干缩率越高，差异干缩则越低。得出了该场柳杉林分木材干缩性能指标的平均水平。 |
| 关 键 词： | 柳杉 干缩率 差异干缩 土层厚度 |

| Abstract: | The wood shrinkage indexes of 23_year_old Cryptomeria fortunei plantation in Changlinggang forest farm were measured and the variations of each index were tested by F test according to different sites. The results showed that variations of the radical_shrinkage and volume_shrinkage of absolute_dried wood on different sites were significant. And site difference had little influence on the whole trunk tangential shrinkage ratio, shrinkage ratio of tangential to radial and gas_dried shrinkage index. The thicker soil is, the higher shrinkage percent and lower shrinkage variation are. The even level of wood shrinkage indexes of Cryptomeria fortunei in this forest farm were concluded in this paper. |
| Keywords: | Cryptomeria fortunei shrinkage ratio shrinkage ratio of tangential to radial soil thickness |
