基于营养供需动态平衡考虑的种群生物量增长模型

本文在种群实际增长是限制性营养供需动态平衡所导致的结果这一假定下,推导出了一个单种群生物量增长数学模型。该模型在形式上与崔-Lawson模型相一致。但其3个参数的生物学意义与崔-Lawson模型有不同的内涵。该模型概括了崔-Lawson模型所不能概括的一类单种群物量增长方式,并给出了不同类型生物量增长方式与种群自身特征和营养再循环的分解条件的关系。本模型的建立和解释具有直观性。

Single population biomass growth model under considering the dynamic equilibrium of supply and demand of nutrients.

On the assumption of real single population biomass growth being resulted from dynamic equilibrium of supply and demand of nutrients, a model of single population biomass growth is developed. The model looks like Cui-Lawson's model, but its three parameters are differed from Cui-Lawson's model's biological meaning. The model can answer under which conditions some growth patterns of single population biomass appear, and can give the relation of single population biomass growth with population itself's intrinsic growth rate and decomposition condition of nutrient recycling. The establishment and interpretation of this model are audio-visual.
