西北地区山杨立木生物量模型研建

Establishment of Single-tree Biomass Equations of Aspen in Northwestern Regions

  • 摘要: 以西北地区山杨为对象,对立木生物量模型研建过程分地上和地下两部分进行了研究,建立了山杨地上生物量、木材、树皮、树枝、树叶独立模型和材积相容模型,同时采用相容性模型方法建立地上生物量和各分量相容的立木生物量模型,还建立了根茎比模型来估计地下部分生物量。研究结果表明,所建立的各模型均达到相关技术规定要求,可以用于西北地区山杨的生物量估计。

     

    Abstract: In this paper,studies were made of the establishment of above-ground and below-ground singletree biomass equations of aspen. Firstly the work was done for establishing its total above-ground,stem wood,stem bark,branch,leaf independent biomass models and compatible models with the volume biomass. Then a system of aspen biomass models was established,in which the total above-ground biomass equations were compatible with stem wood,stem bark,branch,leaf biomass equations. Finally a root-shoot ratio model was established,which could be used to estimate below-ground biomass together with aboveground biomass equation. The results showed that all the models should be able to fulfill technical regulations and to be applied to the biomass estimation of aspen.
