两种生物量模型的比较

A Comparison between CAR and VAR Biomass Models

    摘要
  • 摘要: CAR模型和VAR模型是生物量模型研究与应用中最常用的形式。用再抽样的方法,从模型参数的稳定性、模型的预估能力分析、比较了两类模型,结果得出:CAR模型不仅参数估计值稳定,而且预估能力强。

     

    Abstract: The CAR(Constant Allometric Ratio) and VAR(Variable Allometric Ratio) models were two basic biomass models most widely used in research and applications.Re-sampling and sign test were employed in this paper to compare these two models for their parameters'stabilities and their predictions.The research showed that the CAR model would give more stable parameter and more accurate estimation than the VAR model.
