对欧洲鹅耳枥一年生播种苗的苗高、地径进行测定,利用Logistic、Gompertz 和Von Bertalanffy 3种非线性模型对播种苗苗高的年生长规律进行拟合和分析。结果显示,3种模型的拟合度均在0.95以上,Logistic方程的拟合值较接近于实际观测值,拟合度达0.967,是追踪欧洲鹅耳枥苗高生长的理想模型。同时利用Logistic方程,结合播种苗实际长势,将播种苗生长划分为4个时期：出苗期、生长初期、速生期和生长末期。

In the study, we periodically measured the seedling height and diameter of one-year-old Carpinus betulus. Growth rhythm was fit and analyzed by using three non -linear models of Logistic, Gompertz and Von Bertalanffy. The results showed that the fitness( R2 ) of the three models were up to 0. 95 , and the expected values obtained with Logistic were more closer to the observed values compared with the other two models, with the highest fitness of 0. 967. Meanwhile, based on seedling growth through the whole season, the Logistic was used to divide the growing period into four phases: seeding stage, early stage, fast-growing stage and last stage.
