海南岛苔藓植物研究历史、现状与展望

综述了海南岛苔藓植物的研究历史和现状。目前海南岛已记录的苔藓植物共有87科227属806种,其中苔类33科71属366种,藓类51科152属436种,角苔类3科4属4种;苔藓植物的区系组成以热带亚洲成分为主,与香港、台湾地区的种属相似性高;对海南岛苔藓植物的研究集中在尖峰岭、霸王岭、吊罗山3个国家级自然保护区;叶附生苔是海南热带雨林主要的苔藓生态分布类型之一,共有7科23属123种;初步统计濒危苔藓植物有15种。今后应继续开展广泛和持续的物种多样性调查,从生态学、植物化学、分子生物学等领域进行研究,促进合理的开发利用和推动保护工作。

History, Present Situation and Prospect of Bryological Research in Hainan Island, China

Hainan Island is a tropical island and the second largest island along the coast of China. The history, present situation of bryological researches in Hainan Island were reviewed. Based on published records, there are 806 species of bryophyte in Hainan Island, belonging to 227 genera of 87 families, of which 366 species in 71 genera of 33 families are liverworts, 436 species in 152 genera of 51 families are mosses, and four species in four genera of three families are hornworts. The Hainan Island bryoflora is dominant by Tropical Asian type, and has high phytogeographical similarity to Hong Kong and Taiwan. Regional studies on bryological investigations focused on Jianfengling, Bawangling and Diaoluoshan Nature Reserves. Epiphyllous liverworts is one of the commonest coenotypes of the tropical rainforests in Hainan Island, with 123 species belonging to 23 genera of seven families. There are 15 species of bryophytes from Hainan Island listed in the national red list of China. In the future, it should be considered to carry out the extensive and sustained diversity investigation, develop the researches in bryological ecology, chemistry and molecular biology, and promote the utilization and conservation of bryophytes.
