摘要:
 为了分析广东省橡胶林的群落性质和群落特征，探究广东省不同地区橡胶林林下植物的种类与分布及区系组成成分。通过调查广东省湛江、茂名和阳江的30个400 m2样方的物种组成，分析橡胶林科、属和种的区系成分。结果表明：1）广东省橡胶林群落种子植物共包含51科123属156种。群落优势科（物种数>11的科）为菊科和大戟科，其中最大的科为菊科，包含19个物种；群落中优势属（物种数为4的属）为算盘子属。2）广东省橡胶林群落中包含热带成分的30个科、103个属和122个种；广东省橡胶林群落中热带亚洲的属有12个和种有67个；群落中包含19个全球广布科。3)海南省橡胶林的一些优势科和中等科，如大戟科、锦葵科、芸香科，在广东省橡胶林中同样也占有非常重要的地位，反映了两区域橡胶林在科的组成上存在很大的相似性。广东省橡胶林菊科的物种数占总物种数的比例远高于海南省，而莎草科和梧桐科则相对较小。综合分析表明，广东省橡胶林群落凸显热带性质，但相对弱于海南省橡胶林群落；群落具有一定的热带亚洲成分；此群落存在过渡性并相对强于海南省橡胶林群落。
Abstract:
 In order to comprehend the community characteristics of rubber plantations in Guangdong Province,the types,distributions and flora composition of understory plant species in the plantations were analyzed in this paper.The species compositions of 30 sampling quadrates (20 m × 20 m) were investigated in Zhanjiang,Maoming and Yangjiang in Guangdong Province,and the flora compositions of the families,genera and species were analyzed.The results were as follows.1) There existed 51 families including 123 genera and 156 species,two of which were dominant families (Compositae,Euphorbiaceae) with more than eleven species.Compositae was the largest family with 19 species and Glochidion was the only dominant genera with four species.2) There were 30 tropical families,103 tropical genera and 122 tropical species in the plantations.Also,there existed 12 genera and 67 species of tropical Asia.What’s more,19 families of cosmopolitan were included in the plantations.3) The families,such as Euphorbiaceae,Malvaceae,Rutaceae were very important in the rubber plantations in both Guangdong Province and Hainan Province,which indicated the close floristic affinity in rubber plantations between two zones.The percentage that the species of Compositae occupied the total species in the rubber plantations of Guangdong Province was higher than in the rubber plantations of Hainan Province,and the percentages in Cyperaceae and Sterculiaceae were relatively low.Our results highlighted the flora of the plantations presents the property of tropical zone，which was weaker than that of the rubber plantations in Hainan Province.The community existed the tropical Asia infinity and the transitional characteristics.The transitional characteristics were higher than that of rubber plantation community in Hainan Province.
