摘　　要：对伐期龄5年的刚果12号桉采伐迹地萌芽更新调查结果表明：该树种具有旺盛的萌芽能力，且生长迅速。其伐桩萌发比、桩均株数及有效株平均树高、平均胸径1年生为97．2％、4．3株、2．7m和1.6cm；2年生为95．6％、2．4株、5．6m和4．4cm．显示了萌芽更新作为短轮伐期刚果12号按工业原料林的主伐更新具有高度的适用性。The results reveal that this species possesses a vigorous sprouting capacity and grows fast. Itsstump sprouting percentage, average plant number per stump, average height of effective plants and averaged. b. h. are 97. 2%, 4. 3 plants, 2. 7m and 1. 6cm respectively at the age of one and 95. 6%, 2. 4 plants, 5. 6mand 4. 4cm respectively at the age of two. The above situation indicates that the sprout regeneration is highlysuitable for the final felling regeneration of the short-rotation Eucalyptus ABL12 industrial raw materialforests.
