摘    要:在 35年生的油松人工林中设置 4块标准地 ,分别径阶选定样木 ,测定其生物量。结果表明 :35年生油松人工林每公顷林分总生物量为 76 87t。油松各器官生物量的分配有一定的规律 ,树干生物量占全株生物量的44 0 8%~ 6 4 95 % ,树枝占 18 31%~ 2 8 73% ,树叶占 9 2 %~ 12 94% ,根系占 10 85 %~ 16 38%。林木生物量与径阶有正相关关系 ,与 (D21 3H)有密切相关关系 ,其回归模式为LnW =aLn (D21 3H) +b。

关 键 词:油松  人工林  林木生物量

Abstract:Sample-plots were set in 35 years old standing forest of Pinus tabulaeformis Carr.in TaiHang forest region, in Shanxi province.Sample tree biomass was investigated according to different diameter grade.Results showod that the distribution of biomass a mong different organs is contributed mostly to the trunk,which was about 44\^08%~64\^95%. The branch,the leaf and the root were 18\^31%~28\^73%,9\^2%~12\^94% and \{10\^85%~16\^38%\} respectively.Through the statistics analysis,the correlation between tree biomass and the diameter grade was obviously.Close relationship was between the biomass of various organs , D 2 1.3 H and the patterns of biomass change had been set.
Keywords:Pinus tabulaeformis Carr  Standing forest  Tree biomass
