| 摘 要： | 以广西良凤江国家森林公园27年生麻栎人工林为对象，采用树干解析的方法对麻栎人工林测树因子各年间变化动态进行检测，研究树高(H)、胸径(D)、材积(V)与树龄(T)间的回归关系。结果表明，麻栎人工林树高和胸径的平均生长量曲线和连年生长量曲线出现了多个交叉点，变化幅度较大，但其单株材积生长曲线27 a间处于不断攀升，表现出良好的生长趋势，且各生长曲线表明麻栎的生长在0~4 a为速生期；所拟合回归模型R2均达到0.9以上，检验精度较高，其中树高和胸径最优生长模型均为Korf方程，单株材积最优生长模型为坎派兹模型。得出麻栎人工林在27 a保持稳定的增长趋势，造林前期生长迅速，材积生长尚未达到数量成熟，仍有生长趋势。拟合模型精度较高，可运用于生产实践中。

| Abstract: | Investigation was conducted on the growth regularity of Quercus acutissima in a 27-year-old plantation located in Liangfengjiang National Forest Park, Guangxi, China. Stem analysis method was adopted to examine the dynamic changes of different variables, such as tree height (H), diameter at breast height (DBH), volume, and age (T). Linear regressional model was adopted to examine the relationships among variables. The results showed that several cross were points presented in the curves of average and successive growth of H and DBH, and wide variations were observed. However, the individual tree volume growth curve exhibited a rising trend during 27 a, showing good growing potential. The growth curves of different variables demonstrated that the first 4 years were the fast growing periods. The values of R2 of the simulated models were over 0.9 with high test precision. H and DBH growth models were optimal Korf equation, and the optimal model of individual tree volume growth was Kanpaizi equation. It was concluded that Q. acutissima plantations in the forest park maintained a steady growth trend in 27 years, the trees grew rapidly in their initial stage. The volume growth had not reached its full mature stage, growth potential still existed. The fitting models had high precision, and they could be applied to the practical production. |
