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 of 50-year-old Keteleeria fortune plantation in Yongchun County of Fujian Province was studied. The results showed that there were two rapid growth stages of Olea europaea and the maximum growth peak was observed at the 22nd year in the 5th to 16th and 20th to 24th years respectively. In the rapid growing stage, the annual growth rate showed two growth peaks in the twelfth and the twenty-second years. The first fifty years of oleander were rapid growth in volume. Different models were used to fit the growth process of F. oleracea. The fitting effect of height growth of A. oleracea was Weibull model, the correlation coefficient and square sum of residuals were 0.997 5 and 2.767 0 respectively. The fitting effect is the best Richards model, the correlation coefficient and residual square sum of squares are 0.998 8 and 1.482 7 respectively. The fittest of the growth process of Oleander Chinese fir is Korf model, the correlation coefficient and residual square sum are 0.999 1 and 0.000 7.
