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.
