摘　　要：对中山市树木园马占相思改造林分林下套种的景观树种生长和改造林地生物多样性进行了调查研究,结果表明:改造树种在树高、冠幅和枝下高生长方面较为迅速,但地径生长量变化却相对较小;聚类分析可以将11种改造树种分为3类,即速生树种(盾柱木和高山榕)、中生树种(红花风铃木和樟树)和慢生树种(黄花风铃木、红车等7种);而从生物多样性看,改造林地植物种类数量以及各项指数均有一定的提高。Landscape tree growth and biological diversity of Acacia mangium transformed plantation were investigated at Zhongshan Tree Garden and the results showed that the annual average height and crown growth had increased rapidly while the annual average diameter increased slowly after it was transformed; Clustering analysis was per- formed to classify11 tree species into rapid-growth species（Peltophorum pterocarpum and Ficus altissima）, medium -growth species（Tabebuia pentaphy and Cinnamomum camphora ） and slow-growth species（seven tree species in- cluding Tabebuea chuysantha, Syzygium rehderianum, ect）. As for the plant biological diversity, most index of the trsformed plantation were higher than that of CK.
