| 摘 要： | 最近,关于异速生长模型的讨论再次成为焦点,讨论热点为异速生长指数的取值及其理论解释.本文综述了WBE 97、BMR(99)模型的相关研究,重点介绍了MGL模型及由此模型得到的结果:个体整体的新陈代谢率与个体的质量没有明显依赖关系,其标度指数不是一个固定的值,而是一个区间2/3,1].考虑的视角从个体整体的新陈代谢率转到单位质量的新陈代谢率,通过对不同物种、不同环境的单位质量新陈代谢率的研究,发现对大多数物种,其值落在一个具有普适性的上、下界的区间内；认为存在单位质量的新陈代谢率最小值确定了个体的大小,并建立基于该最小值的描述个体大小与温度关系的数学模型,该模型得到实验数据验证.

| Abstract: | Recently,the discussion on allometric model becomes a hotspot again,with the focus on the scaling exponent and theoretical explanation.This paper summarized the related researches on WBE 97,BMR(99) model,and introduced in especial the MGL model and its deduced results.From the deduction of MGL model,the metabolic rate of whole organism has no obvious dependence on the mass of the whole organism,and the scaling exponent of mass-specific metabolic rate common to most taxa is not a fix value but in 2/3,1].The... |
