摘要：福建省永安市西洋镇2.5a生人促阔叶林分平均胸径、树高、密度、单位面积蓄积量和平均年生长量分别为2.0cm、1.8m、19533株/hm2、7.0m3/hm2和2.80m3/(hm2.a),乔木层物种丰富度R、多样性指数SW、均匀度E和生态优势度ED分别为33、2.93、0.62和0.21,林分相对直径分布范围0.25～3.00,直径分布为反J型,表现为异龄林特征。35a生的伐前林分平均胸径、树高、密度、单位面积蓄积量和平均年生长量分别为13.6cm、10.5m、1185株/hm2、101.3m3/hm2和2.89m3/(hm2.a),乔木层物种丰富度R、多样性指数SW、均匀度E和生态优势度ED分别为24、3.72、0.81和0.10,林分相对直径分布范围0.44～2.50,直径分布为反J型,表现为异龄林特征。
The 2.5 year-old broad-leaved forest by artificial measures promoting regeneration（AMPR）in Xiyang Town of Yong＇an City,Fujian Province was formed after clear cutting of 35 years.old natural broad-leaved forest.Its stand average DBH,height,density,growing stock and annual increment were 2.0 cm,1.8 m,19 533 株/hm2,7.0 m3/hm2 and 2.80 m3/（hm2·a）respectively.Its species richness（R）,Shannon-Wiener index（SW）,evenness（E）and ecological dominance（ED）in arbor storey were 33,2.93,0.62 and 0.21 respectively.Its relative distribution of DBH was from 0.23 to 3.00 and was showed as the distribution of uneven aged forest.The stand average DBH,height,density,growing stock and annual increment of the original forest before clear cutting were 13.6 cm,10.5 m,1 185 N·hm2,101.3 m3/hm2 and 2.89 m3/（hm2·a）respectively.The species richness（R）,Shannon-Wiener index（SW）,evenness（E）and ecological dominance（ED）in arbor storey were 24,3.72,0.81and 0.10 respectively.The relative distribution of DBH was from 0.44 to 2.50 and was showed as the distribution of uneven aged forest.
