Abstract: This study investigated diameter at breast height (DBH) and height of nine years old Eucalyptus dunnii in different site type. The average DBH and height of E. dunnii in mountain forest 1 were 11.6 cm and 11.5 m, the average DBH and height of E. dunnii in mountain forest 2 were 13.0 cm and 13.1 m, the average DBH and height of E. dunnii in riparian forest were 21.3 cm and 17.0 m. The indexs of fast-growing and high yield of E. dunnii in different type lands were higher than local native species, such as masson pine and fir tree, though the growth of E. dunnii in different type lands was obviously different. The differences of indexes due to high growth differentiation of E. dunnii, showed that adaptability of E. dunnii in introduction area was strong.

摘要: 通过标准地调查法,分析邓恩桉9 a生林分在闽北不同立地类型中胸径和树高的生长表现。结果表明,山地林1邓恩桉林分平均胸径和树高分别为11.6 cm、11.5 m,山地林2邓恩桉林分平均胸径和树高分别为13.0 cm、13.1 m,河岸林邓恩桉林分平均胸径和树高分别为21.3 cm、17.0 m。虽然各林分之间生长差异明显,但均超过本地乡土树种马尾松、杉木的速生丰产指标,且这些差异主要是由各林分中出现部分林木向高生长方向分化造成的,是邓恩桉在引种区适应生长的表现。
