| 摘 要： | 对秃杉人工林开展不同造林密度和抚育间伐试验研究 ,结果表明 :随秃杉造林密度增加 ,其胸径、冠幅和整齐度减少 ,枝下高增大。单株生物量随林分密度增加而减少 ,林分生物量及树干和根系占全部生物量比率随密度增大而增加 ,枝条和针叶所占比率随密度增加而减少 ,根据培育目标 ,用下层间伐及中度间伐可切实有效地提高林分生物量和生长量

| Abstract: | The study results indicated that the average diameter and crown width reduced and the average height under branch increased when the plantation densities of Taiwania flousiana increased.The individual biomass reduced with the stand densities adding.The rate of stem and root and the whole biomasses increased with the stand density adding . The rate of the branch and leaf reduced with the stand density increasing. The early thinning,low layer thinning and moderate thinning intensity can improve the stand biomass and growth increment efficiently. |
