鼓浪屿岛种子植物分布区类型初步研究

The Seed Plants Areal Types in Gulangyu Island of Fujian

通过资料搜集并结合实地调查,对鼓浪屿种子植物的区系组成和科、属的分布区类型进行统计分析与研究.结果表明,鼓浪屿种子植物共有308种,隶属于77科202属,其中,国家重点保护野生植物4种,2种为中国特有植物,入侵植物4种,区系组成兼具复杂性与多样性.科的分布区类型以泛热带分布(55%)为主.属的分布区类型同样以泛热带分布(26.63%)为主.本地区种子植物表现出热带、亚热带地区向温带地区过渡的性质;鼓浪屿种子植物区系与福建、广东两省相似性较高.研究结果可为改善鼓浪屿岛生态环境质量提供参考,同时可为岛上植被资源的合理开发利用提供基础资料.

A field investigation and data gathering were carried out, in order to analyze the floristic composition and distributions of families and genera of the seed plants on Gulangyu Island. The results showed that a total of 308 species was found on Gulangyu Is- land, belonging to 77 families and 202 genera. Among them, 4 species were the national key protected wild plants, 2 species were Chi- nese endemic plants and 4 species were invasive plants. In the areal distribution of families, the pantropical type （55%） was predomi- nant, and the pantropical distribution （26.63%） was also dominant in genera areal distribution. Overall, the flora of the seed plants on Gulangyu Island showed the characteristic of transition from tropical and subtropical to the temperate. The seed plants flora of Gulan- gyu Island was similar to that of Fujian and Guangdong. Our results can be a reference for improving ecological and environmental qual- ity on Gulangyu Island, and also provide the basis for the rational development and utilization of its vegetation resources.
