摘　　要：对连香树人工群落平均木个体的地径、胸径、树高和材积的生长规律进行了研究,其结果显示人工种植的连香树在树龄为6年后即开始郁闭,连香树生长极快,6年可郁闭成材。另外,连香树地径生长高峰期在第6～7年龄、胸径生长高峰在第5～6年龄、树高生长高峰在第4～5年龄,材积生长高峰期在第8～9年龄。建立了地径、胸径、树高和材积4个生长模型,均达到极显著水平。The growth law of the basal diameter, diameter at breast height（DBH）, height and volume of the mean individual from artificial community of Cercidiphyllum japonicum were studied in the paper. Result indicated： Artificial plants Cercidiphyllum japonicum begin to forest after 6 years. In addition, the growth peaks of Cercidiphyllum japonicum＇s basal diameter, diameter at breast height（DBH）, height and volume were respectively at 6- 7, 5- 6, 4- 5 and 8- 9 years age. The 4 growth correlation models with basal diameter, diameter at breast height（DBH）, height and volume were established, It is all the most distinct correlation.
