摘　　要：对广东省东莞市绿道网大岭山森林公园段生态景观林带树种组成及群落特征进行调查研究,7种类型的样地调查结果表明:(1)主要乔木优势种为:人面子、大花紫薇、深山含笑、山杜英、木棉等。灌木优势种为灰莉、九里香、山瑞香、金脉爵床、红花檵木、红绒球等;(2)乔木层平均树高为6.40 m,最大值为11.0 m,为木荷,其它依次为铁刀木(10.9 m)、仪花(10.2 m)、木棉(9.8 m);(3)乔木层的H(Shannon-Wie-ner指数)、D(Simpson指数)、J(均匀度指数Evenness)分别为1.72、0.78、0.87;H最大值为2.10,出现在样地7;D最大值为0.83,出现在样地7;J最大值为0.90,出现在样地2、样地4、样地5。The species composition and community characteristic of ecological landscape forest in Dalingsban forest park in Dongguan were analyzed. The results showed that： The main dominant species are Dracontomelon duperreanum, Lagerstroemia speciosa, Michelia maudiae, Elaeocarpus sylvestris and Bombax ceiba, etc. in tree layer, and Fagraea ceilanica, Murraya panicuata, Pittosporum tobira, Sanchezia nobilis and Lorpetalum chinense in shrub layer. The average height of tree layer are 6.40 m, and the tallest is Schima superba （ 11.0 m）, followed by Cassia siamea （ 10.9 m）, Lysidice rhodostegia （ 10.2 m） and Bombax ceiba （9.8 m）. The average value is 1.72, 0.78 and 0.87 for Shannon-Wiener index （H）, Simpson index （D） and evenness index （J）, respectively. The maximum is 2.10 for H in plot 7, 0.83 for D in plot 7, 0.90 for J in plot 2, 4 and 5.
