| 摘要: |
| 比较研究了广东省惠州市惠阳区秋长镇7年生人工生态林33个阔叶树种的生长。结果表明：长叶竹柏(Nageia fleuryi)、乌桕(Triadica cochinchinensis)和白兰(Michelia alba)等8个树种造林早期存活率较低,在荒山造林中生长表现欠佳；其余树种在荒山造林中效果良好。聚类分析结果将26个树种划分为3类：第1类为猴耳环(Archidendron clypearia)、米锥(Castanopsis carlesii)、红锥(C. hystrix)等9个生长快速的树种；第2类为盆架子(Alstonia rostrata)、樟树(Cinnamomum camphora)、肖蒲桃(Syzygium acuminatissimum)等12个生长速度中等的树种；第3类为桂木(Artocarpus lingnanensis)、铁冬青(Ilex rotunda)、麻楝(Chukrasia tabularis)等5个生长缓慢的树种。 |

| Abstract: |
| The growth of 33 broad-leaved tree species in an 7-year-old plantation at Huiyang District, Huizhou City of Guangdong Province were compared. Most other trees are suitable for afforestation in degraded hill lands. Clustering analysis classified the 26 tree species into three groups based on their growth：Group I consisted of nine fast growing trees such as Archidendron clypearia,Castanopsis carlesii, and C. hystrix；Group II consisted of twelve medium growing trees such as Alstonia rostrata, Cinnamomum camphora, and Syzygium acuminatissimum；Group III consisted of five slow growing trees such as Artocarpus lingnanensis, Ilex rotunda, and Chukrasia tabularis. |
