摘要: <正>用相对生长模型W =a(D2 H) b和幂函数改进模型W =aDαHβ,对福建邵武卫闽光皮桦种群生物量进行了研究。结果表明 ,幂函数改进模型要优于相对生长模型 ,并且光皮桦林分总生物量为 33.47t/hm2 ,其生物量大小顺序为树干 >根 >枝 >皮 >叶。

Abstract: This paper used allometric model W= a(D 2 H) b and modified power function model W= aD α H β study biomass of Betula luminifera population at Weiming,Shaowu of Fujian province.The results showed that the modified power function model was superior to the allometric,moreover,the biomass of Betula luminifera stand was 33.47 t/hm 2 and the biomass in size order was trunk>root >branch>bark>leaf.
