Studies on the Flora of Pteridophytas of Mazongling Nature Reserve of Dabieshan

Mazongling nature reserve belongs to the northern part of Dabieshan, which is situated in Jinzhai County. The Mazongling contains 28 families, 55 genera and 89 species (including varieties and forms). The families, genera and species of the pteridophytas are classified and the geographical elements of the pteridophytas are analyzed. The flora of the pteridophytas can be divided into 13 areal types. From much closer to little closer, the sequence of pteridophytas floristic relation between Mazongling and the adjacent regions is Southwest China, Central China, North China, South China, Japan, Northweet China, Taiwan, Northeast China. In contact with 12 mountains in China, the floristic elements of Mazongling are similar to those of Tianmushan, Lushan, Huangshan, Beishan, Jiuhuashan and Qiyunshan, and they should be the same natural flora, but scarcely to the others.
