摘要
海南铜铁岭热带低地雨林的物种种类十分丰富,在2 600 m2的样地中有维管束植物88科、186属、258种.植物分布区类型组成,主产热带、亚热带的科占79.55%,热带分布属占旧世界分布属的95.08%;热带分布种占种总数的98.84%.热带分布的科、属中,以泛热带分布的科、属最多,分别占科、属总数的62.50%,28.49%.种的分布中以热带亚洲分布及其变型和中国特有成分占的比例最高,分别为55.43%和33.72%;分布至温带的科、属、种分别占科、属、种总数的19.32%,4.92%,1.16%.结果显示了铜铁岭低地雨林的热带北缘的性质.
The richness and composition of species in the tropical rain forest are widely concerned recently, especially under the threat of deforestation of rain forest. Based on surveys in the tropical lowland rainforest in Tongtieling, Halnan, 258 species of vascular plant in 88 families and 186 genera are recorded in the area of 2 600 m^2 and the characteristics of floristics was analyzed, the families of mainly tropical and subtropical distribution make up 79.55% in totole family; the genera and species of tropical distribution take up 95.08% and 98.84% in the total, respectively. The families and genera of pantropic distribution take up 62.50% and 28.49%, the species of tropical Asia distribution and its sub-patterns contribute 55.43%. At the same time, the families, genera and species with temperate characteristics make up 19.32%, 4.92% and 1.16% of contribution to the flora of Tongtieling, respectively. The results suggest that flora of Tongtieling belongs to northern margin of tropical but not typical tropical region.
