The Floristic Analysis Of Seed Plant In Mt.Zi-Wei National Forest Park

Based on the Basic project of Ministry of Science and Technology,The investigation of the Biodiversity in East China between Mt.Huangshan-Mt.Tianmu and Xianxia mountain range-Mount Wuyi,The author investigated the flora of Mt.Ziwei National Forest Park with sample method and sample plot method.Through Consultation,Identification and Literature search,we finally found that Mt.Ziwei has 1051 species of seed plants belonging to 138 families and 544 genera.At the level of Family,Compositae,Rosaceae,Gramineae and etc.are the the families with the largest number of specis while the Saururaceae,Alangiaceae,Calycanthaceae and etc.are the Characterizatic families because of their high VFIC(W),while the Tropicos element and Temprature element held the same propotion.At the level of Genus,most of the genera contained not more than 5 species,Pseudotaxus ? Cryptomeria ?Bretschneidera and etc.are the real genera with only one specie while the Pantropicos type and North temp.Type are the main areal-type;At the level of Species,there are 233 species endemic to China which could be put into 8 Subareal-type in China including Endemic to Zhejiang,Endemic to East China and etc.We could reach conclusions that Flora of Mt.Ziwei(1)is rich in variety,the flora origin is ancient,and the geographical compononent are multiform;(2)belonged to the mountainous type in the southern margin of the East China flora,and had the characteristics of the north and South Flora at the same time;(3)is rich in Unique and rare species which is worth further studying.The author also summarized common mistakes in today's floristic study,this research can not only provided theoretical basis of Formulating,Maneging and utilizing the Wild plant resources in Mt.Ziwei but also perfected the basic data in the further study on the Flora of Zhejiang.
