Analysis the Floristic Character of Seed Plants in Wuyanling National Nature Reserve from Zhejiang Province

Wuyanling National Nature Reserve lies in the central subtropics.Its climate is warm and moist.One hundred and thirty four families,578 genera and 1197 species are recorded in this area.According to the information of historical geology and natural conditions,the composition of seed plant flora and the areal-types of genera were analyzed.The results showed that its origin was rather ancient and its geographical compositions were complicated.There were many species of rare and endangered plants,e.g.Taxus chinensis var.mairei,Bretschneidera sinensis,Emmenopterys henryi,Fokienia hodginsii,Torreya grandis,Phoebe bournei,Ormosia henryi,and so on.Most of these plants had high value in economics and scientific research.According to statistics and analysis of genera in the present flora,578 genera were divided into 14 areal-types.The ratio of tropical and temperate genera was respectively 48.6% and 49.2%,so its flora was characterized by transitional floristic elements,and in wide connection with the world.It was nearly correlative with the ancient geologic structure and ascendant natural condition here.
