| 摘 要： | CAR模型和VAR模型是生物量模型研究与应用中最为常用的基本形式 .该文用再抽样的方法 ,从模型参数的稳定性、模型的预估能力上较全面地分析与比较了两类模型 .通过对CAR和VAR模型比较得出 :CAR模型相对VAR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 wer e two basic biomass models most widely used in research and applications. Re\|sa mpling and sign test were employed in this paper to compare these two models for their parameters' stabilities and their predictions. Research showed that the C AR model would give more stable parameter and more accurate estimation than the VAR model. |
