摘要
为了解东北林蛙的生长规律,运用Gompertz、Logistic和Von Bertalanffy3种非线性模型分别对东北林蛙一龄和二龄生长期间体重数据进行了曲线拟合和分析。结果表明:3种模型都能很好地模拟东北林蛙的生长曲线,但Logistic曲线模型的拟合效果最好。结果显示,运用3种模型对东北林蛙进行生长曲线的拟合和分析是可行的。
To study the development rules of Rana dybowskii,the growth of Rana dybowskii from 0 to 14 weeks old was analyzed and fitted with three kinds of nonlinear models（Gompertz,Logistic,and Von Bertalanffy）.The growth curves were appropriately fitted with three models.But the Logistic growth model had the best effect on fitting with the growth curves.It is feasible to analyze and fit the growth curve of the Rana dybowskii using the three models.The results provided a reference for keeping abreast of the growth rule of Rana in northeast.
