    摘要:

    通过野外调查和资料整理,统计分析梅花山自然保护区蕨类植物区系组成和分布区类型,比较其与周边相邻4个自然保护区的蕨类植物区系的相似性。结果表明:(1)梅花山自然保护区共有蕨类植物42科83属189种,科、属组成优势现象明显,区系起源古老。(2)分布区类型在科、属级水平上以泛热带分布和世界分布为主,种级水平以热带亚洲分布、东亚分布和中国特有分布为主,热带亲缘明显,具有由热带向温带过渡的性质。(3)在地理亲缘关系上,梅花山与梁野山的蕨类植物区系联系最为紧密,与圭龙山的关系次之,与热带区系性质较强的南靖南亚热带雨林自然保护区和典型的中亚热带性质的武夷山自然保护区的蕨类植物区系联系较为疏远,具有从南亚热带向中亚热带过渡的明显特点。

    Abstract:

    Through field investigation and data collation, the flora composition and distribution types of Pteridophytes in Meihua Mountain Nature Reserve were analyzed, and the similarities between the Pteridophyte Flora of Meihua Mountain Nature Reserve and the four adjacent nature reserves were compared. The results show that: (1) there are 189 species of pteridophytes belonging to 83 genera and 42 families in Meihuashan Nature Reserve. The dominant composition of families and genera is obvious, and the flora originates from ancient times. (2) The distribution types are mainly pantropical and worldwide at the level of families and genera, and mainly tropical Asia, East Asia and endemic to China at the level of species. The tropical relatives are obvious and have the character of transition from tropical to temperate zone. (3) Geographically, the fern flora of Lingyeshan Mountain is closely related to the fern flora, followed by Guilongshan Mountain. The fern flora of Nanjing South Asian Tropical Rainforest Nature Reserve and the typical Wuyishan Nature Reserve of Central Subtropical Nature Reserve are far away from each other. They have obvious characteristics of the transition from South subtropical to Central Subtropical.
