东省东江林场 15 个阔叶树种人工林为研究对象, 对比分析 16 a 生和 7 a 生林分生长变化, 以期为丘陵地
区造林树种选择提供参考。 结果表明: 15 个树种间 16 a 生胸径、 树高和冠幅差异显著 (P<0. 05)。 相对
于造林后 7 年内的生长表现, 红锥 Castanopsis hystrix、 翻白叶树 Pterospermum heterophyllum、 南酸枣 Choerospondias axillaris 等在 8~16 a 生长速度下降明显; 木荷 Schima superba、 黧蒴 Castanopsis fissa、 火力楠
Michelia macclurei 等则生长较快。 通过聚类分析将 15 个树种分为三类, 南酸枣、 荷木、 黧蒴、 火力楠、
山杜英 Elaeocarpus sylvestris、 山桂花 Paramichelia baillonii、 西南桦 Betula alnoides 属于速生树种, 樟树
Camphora officinarum、 青冈 Quercus glauca、 阴香 Cinnamomum burmanni、 海南红豆 Ormosia pinnata、 枫
香 Liquidambar formosana、 翻白叶树、 红锥属于中等速生树种, 格木 Erythrophleum fordii 属于慢生树种。
研究通过对比各地树种的生长表现, 提出丘陵地区树种选择和应用建议, 对森林质量提升具有指导意义。 |

| Abstract: |
| Mastering the growth characteristics of tree species is the important foundation for implementing
the principle of species-site matching, and plays an important role in forest quality improvement. Plantations of
15 broad-leaved tree species were investigated in Guangdong Dongjiang Forest Farm, and their tree growth per- formance at 16 and 7 years old was compared to reveal their growth stability, aiming to provide a reference for
tree species selection in hilly areas in South China. The results showed that there were differences in diameter at
breast height, tree height, and crown width among 15 tree species when 16 years old. The growth rate of Castanopsis hystrix, Pterospermum heterophyllum, and Choerospondia axilaris decreased remarkably during eight
to 16 years old compared to those within seven years after planted, while Schima superba, Castanopsis fissa,
and Michelia macclurei had faster growth rates from eight to 16 years old. The tree species could be divided into
three categories through cluster analysis on the basis of their growth performance at 16 years old, the fast-growing tree species include Choerospondias axillaris, Schima superba, Castanopsis fissa, Michelia macclurei,
Elaeocarpus sylvestris, Paramichelia baillonii, Betula alnoides; Moderately fast growing tree species include
Camphora officinarum, Quercus glauca, Cinnamomum burmanni, Ormosia pinnata, Liquidambar formosana,
Pterospermum heterophyllum, Castanopsis hystrix; only Erythrophleum fordii belongs to the slow-growing tree
species. Based on comparisons of the growth performance of these tree species in different regions of Guangdong
province, some suggestions on tree species selection and application be pointed out in hilly regions, which could
provide a reference for forest quality improvement |
