摘要: 提出自适应种群增长新模型S=exp(αln2 (1+ce-rt) +βln(1+ce-rt) +γ),该模型包融了Logistic模型、Smith模型、Gompertz模型、崔-Lawson模型、张-Logistic模型和刘-Logistic模型.运用遗传算法对自适应新模型进行参数估计,拟合青钩栲种群增长规律比其它种群增长模型更符合青钩栲种群增长的实际增长趋势,说明新模型具有一定的实用价值.

Abstract: In this paper,a new self adaptive model for population growth,i.e. S= exp (αln2(1+ce-rt)+βln (1+ce-rt)+γ) was established,which combined Logistic,Smith,Gompertz,Cui-Lawson,Zhang-Logistic and Liu-Logistic models.Estimations with genetic algorithm showed that the new model was more suitable than other models to simulate the actual growth trend of Castanopsis kawakamii population.
