关键信息功能分支分析（FBA）是一种有前途的非破坏性方法，可以产生准确的树木生物量方程时，适用于树木表现出分形brancharchitecture.AbstractFunctional分支分析（FBA）是一个有前途的非破坏性替代标准的破坏性方法的树木生物量方程的发展。在FBA中，树木分枝结构的理论模型通过测量树干和树枝来校准，以估计生物量方程的系数。在这项研究中，物种特异性和混合物种的树木生物量方程来自破坏性采样的树木在肯尼亚西部，并与树木生物量方程来自非破坏性FBA。结果表明，非破坏性的FBA方法可以产生生物量方程，类似于，但不准确，比那些来自标准方法。FBA生物量预测偏差是由于这样一个事实，即真实的树木偏离分形分支结构，由于高度可变的长度-直径的关系的茎和分支和不准确的缩放关系的长度的树冠和树干假设下的FBA模型。
Key messageFunctional branch analysis (FBA) is a promising non-destructive method that can produce accurate tree biomass equations when applied to trees which exhibit fractal branching architecture.AbstractFunctional branch analysis (FBA) is a promising non-destructive alternative to the standard destructive method of tree biomass equation development. In FBA, a theoretical model of tree branching architecture is calibrated with measurements of tree stems and branches to estimate the coefficients of the biomass equation. In this study, species-specific and mixed-species tree biomass equations were derived from destructive sampling of trees in Western Kenya and compared to tree biomass equations derived non-destructively from FBA. The results indicated that the non-destructive FBA method can produce biomass equations that are similar to, but less accurate than, those derived from standard methods. FBA biomass prediction bias was attributed to the fact that real trees diverged from fractal branching architecture due to highly variable length–diameter relationships of stems and branches and inaccurate scaling relationships for the lengths of tree crowns and trunks assumed under the FBA model.
