摘　　要：在福建省莆田市仙游县西北部山区较高海拔山地以巨尾桉、巨桉、巨赤桉为对照,开展了邓恩桉的引种造林试验。结果表明:邓恩桉在该地区有较好的生长量和抗寒能力,在海拔高度500 m以上的区域邓恩桉基本能适应,2～3年生时,年平均树高、胸径和林分蓄积生长量分别达2.6～3.3 m、3.5～4.0 cm和8.2～23.6 m3/hm2,均超过福建省巨尾桉、尾巨桉短周期工业原料林生长量指标。初步认为,邓恩桉适合在该区海拔不超过700 m、立地等级为Ⅱ类或Ⅱ类以上的立地上造林。An experiment on introduction and afforestation of Eucalyptus dunnii was conducted at the relatively high altitude of northwest mountainous areas in Xianyou County,Fujian Province.The hybrid of E.veneer and E.grandis,E.grandis and hybrid of E.grandis and E.camaldulensis were chosen as control in the experiment. The results showed that E.dunnii had a relatively good mass growth and cold resistance.E.dunnii could be basically adapted to site condition at the areas with the altitude over 500 m.The annual average height,diameter at breast height（DBH）,and volume-increment of whole stand of 2~3-year E.dunnii forest could reach 2.6~3.3 m,3.5~4.0 cm and 8.2~23.6 m3/hm 2 respectively,exceeded the mass growth value of Fujian provincial standard for short rotation industrial plantation of E.veneer and E.grandis×E.urophylla.The E.dunnii is suitable for afforestation in the areas with site type of grade 2 or over grade 2 and altitude of 700 m or less.
