| 摘 要： | 在30 a生油松人工林中设置5块不同密度的标准地,分别选定样木,测其地上部分生物量,再换算到整个样地的平均生物量。结果表明:相似立地条件下,30 a生油松人工林在2 200株/hm2~4 400株/hm2一定密度范围内地上部分总生物量随样地林分密度递增而增大,总叶面积却随密度增加而减小。

| Abstract: | In 30a standing forest of Pinus tabulaeformis Carr.5 pieces of standard land with different densities were set,the sample trees were choosen separately,the above ground biomass was determined and then changed into the average biomass of the whole piece of land.The results showed that under the similar standards of growing conditions at a certain range of densities the t otal biomass increases as the density of the sample increase. |
