[目的]了解云南橡胶林群落种子植物的物种组成和区系成分等基本特征.[方法]调查了西双版纳、普洱、红河、临沧和德宏等的56个100 m2橡胶林样方的植物并进行数据统计分析.[结果]云南橡胶林群落共有野生种子植物90科292属414种,其中优势科优势明显,前15个科计有224种,占总种数的54.11%.云南橡胶林群落凸显热带性质,科、属和种的R/T值依次为7.14、10.74和15.38;群落中热带亚洲成分有46属211种;群落中还有32个全球广布科和59个中国特有种.云南、广东和海南橡胶林群落的9个优势科中有5个共有科,表明三地群落在科的组成上存在一定的相似性.[结论]云南橡胶林群落呈现热带性质,稍强于广东但不及海南,并且具有一定的热带亚洲成分和特有现象,在三地群落中最为显著.
Studies on the Flora of the Seed Plants of Rubber Plantations in Yunnan Province
[Purposes] The aims of this study were to analyze the composition of species and flora of seed plants in rubber plantations in Yunnan Province.[Methods] The plants of 56 quadrates (10 m x 10 m) were investigated in rubber plantations in Xishuangbanna,Puer,Honghe,Lincang and Dehong,and then the statistical analysis was conducted.[Results] There were 414 seed plant species,belonging to 292 genera and 90 families in the plantations.The 15 dominant families contained 224 species,which occupied 54.11% of the total species.The property of tropical zone was evidently presented in the flora of the plantations,and the R/T of family level,genera level and species level were 7.14,10.74 and 15.38 respectively.Also,there were 46 genera and 211 species of tropical Asia.What's more,32 families of cosmopolitan and 59 Chinese endemic species were also included.There were 5 common families among 9 dominant families of rubber plantations in Yunnan,Guangdong and Hainan Provinces,which showed a certain similarity existing in the families composition of three communities.[Conclusions] The characteristics of tropical zone are obviously presented in rubber plantations of Yunnan Province,which is slightly stronger than the characteristics of Guangdong rubber plantations and is sharply weaker than the characteristics of Hainan rubber plantations.The tropical Asia infinity and endemism also exist in the plantations of Yunnan Province,which are both the strongest in the three communities.
