| 摘 要： | 为了研究天然丝栗栲的生长规律，以及对丝栗栲树种的生长趋势进行预估，以福建南平延平区天
然丝栗栲解析木资料为基础，通过树干解析的方法和方程的拟合，对丝栗栲的胸径、树高、材积随年龄变
化的规律进行分析研究。结果表明：福建省延平区天然丝栗栲的胸径、树高、材积总生长量都随年龄的
增加而增加，天然丝栗栲的胸径、树高的最优生长模型为二次曲线模型，材积的最优生长模型为
Richards 和Korf 2 个模型。树木生长前10 年，生长速度较快，在树高上反映较明显。幼龄树苗的成长最
为迅速。在培养时，应特别注重幼龄树苗的水、肥管理，以提高丝栗栲的生长量。

| Abstract: | In order to study the growth regularity of natural Castanopsis argesii and estimate the development of it. Based on the Castanopsis fargesii＇s analytic material in Yanping, Fujian, through the stem analysis method and the fitting of the equation, the author studied the law about how Castanopsis fargesii＇ s diameter at breast height, tree height, volume change with age. The results showed that： the natural Castanopsis fargesii diameter at breast height, tree height, volume total increment increased with age growing in natural circumstances in Yanping, Fujian, the best growth model of natural Castanopsis fargesii diameter at breast height, tree height of was quadratic curve model, the best growth model of volume was Riehards and Korf. When tree growth was 12, the speed of growth was faster. The juvenile seedling grew quickly, in order to improve the growth of Castanopsis fargesii, people should pay attention to its watering and fertilizer management especially, when cultivating in order to improve the increment of Castanopsis fargesii. |
