| 摘 要： | 通过对滨海盐碱地23年实生刺槐生长研究,进行树干解析,对刺槐树高、胸径和材积生长规律进行回归模拟。最优模拟方程为:H=-0.372+3.318*lnt;DH=e(-5.518+0.977/t);BV=e(-13.771-0.938/t)。与传统的S型生长曲线不同。并且通过树高、胸径和材积分别有序聚类,将H、DH、BV都分成三类。分析结果与模拟回归吻合较好。 |

| Abstract: | The growth of 23 year Robinia pseudoacacia seedlings on coastal saline-alkali soil were studied to analyze their height,diameter at chest height and volume by regression analysis.The regression was that： H=-0.372＋3.318＊ lnt;DBH=e（-5.518＋0.977/t）;BV=e（-13.771-0.938/t.The height,diameter and volume were divided into 3 stages through sequential cluster analysis.The result of analysis and stimulation coincided well. |
| Keywords: | Coastal saline-alkali soil Robinia pseudoacacia Regression analysis Sequential Cluster Method |
