【摘要】 为调整森林树种结构，提高森林质量和综合效益，广西东部的国有大桂山林场从桂西北天然分布区引种香合欢(Albizia odoratissima)。对其4年生引种林分进行了调查，结果表明：香合欢具有较好的适应性，林木保存率达到95.3%,平均树高4.19 m,平均胸径4.6 cm,平均冠幅2.36 m,郁闭度0.5,树高和胸径均呈正态分布，主干通直和较通直的林木比例高达77.4%,林木没有遭受中度及以上林业有害生物为害，适宜培育用材林。更多还原

【Abstract】 In order to adjust the structure of forest species and improve forest quality and comprehensive benefits, the State-owned Daguishan Forest Farm located in the east of Guangxi introduced Albizia odoratissima from its natural distribution area in the northwest of Guangxi. The four-year-old introduced forest stands were investigated. The results showed that Albizia odoratissima had good adaptability, the preservation rate of trees reached 95.3%,the average tree height was 4.19 m, the average DBH was 4.6 cm, the average crown width was 2.36 m, and the canopy density was 0.5. The tree height and DBH showed normal distribution, and the proportion of straight and straighter trunk trees was as high as 77.4%. The trees were not damaged by moderate and above forestry pests, and were suitable for cultivating timber forests.更多还原
