Floristic Analysis on Vascular Plants of Sanqingshan Mountain in Jiangxi Province

The Sanqingshan Mountain locates in the east of Huaiyu Ranges,which is in the northeast of Jiangxi Province.There are various species of vascular plants in Sanqingshan with 1915 species(involving variants,subspecies and forma) belonging to 878 genera of 193 families.Based on the investigation and statistical analyses of distribution types,for families,the pantropical distribution is the most of 34.2%,the cosmopolitan distribution is 31.09% and the north temperate zone is 15.03%.Temperate elements are less than tropical elements with the ratio of 41:90.And for genera,the north temperate zone is 17.88%,the pantropic type is 14.81% and the East Asia type 12.76% at generic level,with the temperate elements are slightly more than the tropical elements(427:341).At species level,the Endemic to China type reaches 48.92%,the East Asia type30.73%,and the tropical Asia type 6.73%,and the temperate elements are much more than the tropical elements(705:245).The specific areal types indicate that the floristic characteristic of the reserve is obviously subtropical montane nature.According to the regionalization of Chinese flora,the authors propose that the Endemic to China type can be divided into 12 subtypes,of which the subtype of East-,Central-and Southwest-(South-) China takes the biggest proportion.It reflects the relationships among the floristic elements mentioned above.
