毛白杨枝条生物量估算研究

Study on Biomass Estimation of Populus tomentosa Carr. Branch

枝条生物量是树木生物量的重要构成部分,估算枝条生物量对估算乔木生物量具有十分重要的作用。以毛白杨枝条为对象,研究了其生物量与基部直径、中部直径和长度的关系。结果表明,基部直径是毛白杨枝条生物量的最佳估算指标,估算方程以指数方程最好。

Biomass of branch is an important part of tree,and it plays an important role to estimate biomass of branch for tree biomass.Relationships of biomass of branch with base diameter,mid-diameter and length were studied by branch of Populus tomentosa Carr.. The results showedthat base diameter was suitable to estimate biomass of branch and the best formation was exponential equation.
