| 摘要: |
| 以树木各分量生物量成比例为基础，利用树木各分量生物量这间存在相对生长关系，构建各分量生物量模型通式，采用模型评价指标，逐步剔除模型中参数变动系数大的变量，从而建立树木各分量生物量的最佳模型。 |

| A new approach to the development of biomass model |
|
|
| Abstract: |
| The optimum biomass model for each component of the trees will be developed on the basis of the proportional relations among biomass of different organs of a tree.Firstly,a common biomass formula of a tree,s component should be developed in the light of the allometric growth relationship among each organ,and variants with comparatively greater coefficients of parameter variation will be eliminated gradually by applying model evaluation indexes. |
| Key words: biomass model allometric growth coefficient of parameter variation evaluation index |
