提出自适应种群增长新模型S =exp(αln2 ( 1+ce-rt) +βln( 1+ce-et) +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 A new model of self-adaptive population growth is proposed, which includes Logistic model, Smith model, Gompertz model, Cui Lawson model, S = exp (αln2 (1 + ce- rt) + βln Zhang Logistic model and Liu Logistic model.Using genetic algorithm to estimate the parameters of the new adaptive model, the law of growth of the fitted Hook’s Gurnard is more in line with the actual growth trend of the population growth of Giant Hook’s Gossamer than other population growth models, which shows that the new model has a certain The practical value
