摘要
根据82年生的黄樟（Cinnamomum porrectum）树干解析数据,对江西九连山常绿阔叶林中黄樟的树高、胸径、材积的生长过程进行分析,采用有序聚类分析方法,将树高、胸径和材积划分为4个生长阶段。结果表明,10-30龄阶为树高生长速生阶段,60-80龄阶为胸径、材积速生阶段,黄樟数量成熟期较晚,可作大径材培育,并在工业原料林、混交林、乔灌复合经营以及四旁绿化中应用。
Based on a stem analysis data of 82-year-old Cinnamomum porrectum in Jiulianshan Mountain of Jiangxi province,analyzed C. porrectum tree height,DBH,volume growth process,using the sequential sample cluster analysis method. The tree height,DBH,volume growth is divided into four growth stages. The results showed that 10- 30 age class is the rapid growth stage of tree height,60- 80 age class is the rapid growth stage of DBH and volume. Quantity maturity of C. porrectum is relatively late,can be used for large- diameter timber cultivation,and applied to mixed forests,industrial raw material forest,shrubs and trees compound management as well as garden greening.
