| Abstract: | Based on field investigation and indoor data statistics,there are 207 species(including subspecies and variety) of pteridophyte which belong to 88 genera and 44 families in this area.The dominant families are Dryopteridaceae,Polypodiaceae,Thelypteridaceae and the dominant genera are Dryopteris,Asplenium,Pteris.A detailed floristic analysis reveals that dominant families and genera are pantropical and tropical Asia;the tropical Asian species are dominant,which constitute 34.8% of the total species(excluding the cosmopolitan).The peteridophyte flora is abundant in eastern Asian species and the species that are endemic to China.The ecological features are as follows: rich species of sciophytes,mesophytes and terraphytes;higher proportions species of epiphytes,which constitute 27% of the total species;lower proportions species of heliophytes,xerophytes and lithophytes. |
