摘　　要：选取广西国有东门林场80年代引种的大花序桉(Eucalyptus cloeziana)进行研究,对29年生大花序桉的胸径、树高、材积和干形等指标进行分析,发现其胸径、树高和材积分别达到33.17 cm、33.6 m和0.92 m^3,并拟合得出长周期经营大花序桉的胸径、树高和材积生长模型。通过分析对比相似年限的不同大中径材用材树种,发现大花序桉的生长具有明显优势,同时在不同的桉树种中大花序桉也具有明显的培育优势。The Eucalyptus cloeziana of the Dongmen State Forest Farm of Guangxi was introduced from the 1980s. The diameter at breast height, tree height, volume and dry shape of the 29-years-old large inflorescence were studied, the results showed that the diameter at breast height, tree height and volume were 33.17 cm, 33.6 m and 0.92 m^3, respectively, and the optimal model of diameter at breast height, tree height and volume growth regression of long-period Eucalyptus cloeziana were fitted out. By analyzing and comparing different large and medium-sized timber species with similar years of the Eucalyptus cloeziana, it is found that the growth of Eucalyptus cloeziana has obvious advantages, and even in different eucalyptus species, the Eucalyptus cloeziana also has the significant advantage in cultivation.
