| 摘 要： | 应用MATLAB6．5软件，采用经典理论生长方程Logistic方程、Richards方程、单分子式（Mitscherlich）方程对苏北平原建湖县农田防护林I-72杨的平均高、优势高、平均胸径、平均材积生长数据进行曲线拟合．结果表明，Logistic方程拟合胸径、平均高生长效果最好，而Richards方程拟合优势高、材积生长效果最好，并运用拟合模型结果进行立地质量评价和成熟龄确定．

| Abstract: | Applying software MATLAB6.5,selecting classical growth function of logistic and Richards and Mitscherlich,the growth model of average height,advantage height,average diameter in breast height and volume of poplar I-72 of shelterbelt in jianhu county were established . The result of function curve estimation shows that the logistic function is the best function for DBH and average height , the Richards function is the best function for advantage height and volume. Assessment of the site quality was carried out and the age of maturity was decided according to the result of the model. |
