A floristic statistics and analyses of seed plants of Fengyangshan Nature Reserve in Zhejiang Province.

Based on investigation and statistical analyses,the flora of seed plants of Fengyangshan Nature Reserve(Mt.Fengyangshan)in Zhejiang Province is studied in the present paper.There are 1448 species and varieties,659 genera and 164 families of seed plants in the nature reserve. The areal types of families,genera and species are analyzed respectively.The pantropic type of families reaches 40 9%,cosmopolitan type 20 7%,and north temperate one 19 5% according to the statistics of plant families,which indicates that temperate elements are less than tropical ones(47:81).The pantropic type is 20 5%,the north temperate type is 18 0% and the East Asia one 17 1% at generic level, and the temperate elements are slightly more than the tropical ones(308:277).At species level,the endemic to China type reaches 46 9%,the East Asia type 26 0%,and the tropical Asia one 13 7%,and the temperate elements are much more than the tropical ones(501:264).The areal types at species indicates that floristic characteristics of the reserve is obviously subtropical montane.According to the regionlization of Chinese flora,the authors propose that the endemic to China type can be divided into 9 subtypes, of which the subtype of East-,Central- and South- China takes the biggest proportion.It reflects the relationships among the floristic elements mentioned above.
