摘要
Logistic模型与McDill-amateis模型的参数有明确的生物学意义,能较好的反映林木的生长过程,其参数的拟合有多种方法,应用基于实数编码的遗传算法目标适应函数采用误差平方和比例数取得了理想的结论.
Parameters of logistic model and McDill - amateis model have specific biological meanings and they can reflect the growth process of forest timbers. There are several methods for the fitting of parameters of these two models. Better results were obtained in this paper than those in references cited by using genetic algorithm based on real - coding and reciprocal error square sum in object fitness function.
