| 摘 要： | 设定了长岭岗林场23年生柳杉人工林木材密度指标，分析立地条件对柳杉木材密度的影响，同时讨论了改善木材密度的方法。结果显示；立地条件对柳杉全干密度的影响差异显著，全干密度的差异主要是由土层厚度和土壤肥力的差异所导致。薄土陡坡及山脊上林木的气干密度和基本密度高于其它3种类型的密度指标。

| Abstract: | The wood density indexes of 23-year-old Cryptomeria fortunei plantation in Changlinggang forest farm were measured and the density variation with different sites was studied in this paper.The results showed that the absolute density on different sites was significant.The variation of absolute density on different sites was due to the different soil thickness and fertilization.The air-dried density and the basic density on thick-scarp and ridge were higher than the other three types.The methods of improving the density were discussed. |
