摘要

摘要: 采用全面踏查结合文献研究的方法，对海南文昌地区维管植物组成、区系成分、分布区类型进行了研究。结果显示，文昌地区共计有维管束植物201科777属1397种，其中蕨类植物31科46属67种，种子植物170科731属1330种；野生种子植物634属1183种（包括珍稀濒危植物25种，海南特有种49种）。在属级水平上，文昌植物区系以热带成分占绝对优势，热带、亚热带成分占非世界分布总属数的93.23%。在种级水平上，热带亚洲成分和中国特有成分是该地区植物区系的主要组成部分，其中热带亚洲分布及其变型的分布种最多，占非世界广布种的47.26%；中国特有种占非世界广布种的12.01%。此外，村落风水林保存了大量当地珍稀植物和古树名木，对当地生物多样性保护具有重要意义，建议当地政府加强对村落风水林的保护。

Abstract: The composition, floristic elements, and distribution of vascular plants in Wenchang area of Hainan Province were investigated and analyzed by field investigation and literature research. A total of 1397 vascular species from 201 families and 777 genera were recorded in Wenchang, among which 67 species belonging to 46 genera and 31 families were pteridophytes, 1330 species belonging to 731 genera and 170 families were spermatophyte, and 1183 species belonging to 634 genera were wild seed plants, including 25 rare and endangered species and 49 Hainan endemic species. At the genera level, tropical elements were dominant in the local flora, accounting for 93.23% of non-cosmopolitan genera. At the species level, tropical Asia and Chinese endemic species elements were dominant in the local flora, accounting for 46.65% and 12.01% of non-cosmopolitan species, respectively. In addition, village fengshui forests have preserved many local rare and endangered species, as well as ancient and famous trees, which play a significant role in the protection of local biodiversity. Thus, we recommend that the local government strengthen the protection of these forests.
