Based on the investigation and data access,the floristic analysis of pteridophyte in Ganj iangyuan Nature Re-serve was studied.The results indicated that in this area there were 216 species of ferns belonging to 75 genera in 35 families,and the ratio of these families,genera and species accounting for the total number of ferns in Jiangxi Province was 71.4%,65.8% and 49.9%,respectively.The number of families containing more than seven species was 9,and the families in tropical and subtropical distribution accounted for 74.3% in the family areal types.The number of the genus areal types was 10.The tropical distribution type had 51 genera,which accounted for 68% of the total genera, while the temperate distribution type had 4 genera,which accounted for 5%of the total genera.The geographic distri-bution of species can be divided into four types,including 35.6% ingredients,49.1% subtropical elements and about 13.4%unique components of China.The species similarity analysis showed that this flora and Qiyunshan were closely related,and the similarity coefficient was 7 5 .1%.
