摘要：依据生物体各部分器官与测树因子之间存在着相对生长规律，以树围（Ｇ）和Ｄ２Ｈ为自变量建立橡胶树树叶、树干、小枝、树根、树头、地上、地下部分及全株生物量估测模型，经综合检验，确认以树围为自变量的模型优于以Ｄ２Ｈ为自变量的模型。并利用此模型对更新橡胶林的生物量进行了估测，同时建立了橡胶树生物量表。
Allometric regression equations for biomass prediction were developed fortrees of Hevea brasiliensis in the Leizhou peninsular region of Southern China. Individual treecomponent dry weight,such as leaf, branch,bole,root, bark, total aboveground and under-ground,whole tree were regressed against girth(at breast height 1.3 m)and D2 H(D di-ameter at breast height,H total height)using 49 sample trees. The statistical comparisonshowed that the regression equation against girth was better than that of against D2H. In 25-year-old rubber plantation,approximately 80%of tree biomass was in the aerial part and20%in the roots. The bole,branches, roots and leaves constituted about 52.0%, 23.6%,19.7%and 4.7%of the whole tree biomass respectively.The revised biomass table using re-gression equation against girth was developed.
