以广东省台山市5种树种的幼苗为试验材料，测定其冠幅、树高、胸径、叶面积和叶干重，检验其相关关系，并进行聚类分析。研究结果表明，大叶相思为早期速生树种，具有极强的环境适应性，是首选的推广树种；红锥、荷木和樟树长速中等；红花荷为早期慢生树种。%The crown width, height, diameter at breast height,leaf area and dry weight of five broadleaf plan-tations were studied in Taishan, Guangdong Province, and their relationships were analyzed based on correla-tion analysis and cluster analysis. The results showed that Acacia auriculiformis was the fast-growing tree species with strong environment adaptability, which should be consided as the first choice to popularize; Cas-tanopsis hystrix, Schima superb and Cinnamomum camphora were species growing with medium speed, whereas Rhodoleia championii was the species with slow growth.
