摘　　要：对位于福建省永春县50年生油杉（Keteleeria fortune）人工林的生长规律进行研究。结果表明：油杉树高有2个快速生长期,分别在第5~16年和第20~24年,连年生长量在第22年时出现生长最大峰值;油杉前26年均为胸径的快速生长期,连年生长量在第12年和第22年时出现2次生长高峰;油杉前50年均是材积快速生长期。采用不同模型对油杉生长过程进行拟合,对油杉树高生长过程拟合效果最好是Weibull模型,其相关系数和残差平方和分别为0.997 5和2.767 0;对油杉胸径生长过程拟合效果最好是Richards模型,其相关系数和残差平方和分别为0.998 8和1.482 7;对油杉材积生长过程拟合效果最好是Korf模型,其相关系数和残差平方和分别为0.999 1和0.000 7。The growth regularity of 50-year-old Keteleeria fortunei plantation was studied in Yongchun County, Fujian province. The results showed that the tree height of Keteleeriafortunei had two fast growth periods, which were from the 5th to the 16th year and the 12th to the 24th year. Successive growth showed the maximum peak in the 22na year. The fast growth stage of DBH was 26 years ago. Successive growth appeared two peaks at the 12th and the 22na year. The fast growth stage of volume was 50 years ago. By fitting the growth process of Keteleeriafortunei using different models, the Weibull model had the best fit- ting effect in growth process of tree height. The correlation coefficient and the sum of squared residuals were 0. 997 5 and 2. 767 0 respectively. The Richards model had the best fitting effect in growth process of DBH. The correlation coefficient and the sum of squared residuals were 0. 998 8 and 1. 482 7 respec-tively. The Korf model had the best fitting effect in growth process of volume. The correlation coefficient and the sum of squared residuals were 0. 999 1 and 0. 000 7 respectively.
