A Floristic Analysis on the Gymnosperms of Fujian Province

In this paper, fieldworking,literature and data consulting,floristic analysis method have been taken through the research of the gymnosperms of Fujian Province. Those conclusions may be drawn as follow: (1) Being located in the south-eastern part of China along the coast,belonging to typical monsoon climates and above 50% mountainous landforms made Fujian suitable for living and breeding of plants.(2) The gymnospermous flora of Fujian Province consists of 9 families, 24 genera and 44 species(including one endemic family,six endemic genera and 26 (ende-)(mic) spcies), accounting 90.0%,70.59% and 19.13% for corresponding taxa of China, being an important part of the gymnospermous flora of China, too.(3) The data of palaeobotany and age-old,relict,endemic compositions illustrates that the origin of gymnospermous flora of Fujian is age-old; Through geologic distribution analysis of genera types and species subtypes, there are a few the genera tropical composition (only 25.0%), and abundant of the subtropical to temperate ones(up to 75.0%,41.67% in which are subtropical compositions); there are 67.10% subtypes of subtropical species, the results show that gymnospermous flora of Fujian has notable subtropical mountainous character and may be from the subtropical mountains of China.(4) About 30% species such as Tsuga. longibracteata,Fukienia hodginsii,Pinus taiwanensis,Cryptomeria fortunei,Cunninghamia lanceolata et al, are distributed in the mountainous landforms. (5) Among species areal-types, there are 35 species distributed in Nanling Mountains, Nanling mountains not only provides migration passageway for the subtropical compositions of southwest core region, supplies path for tropical compositions of Trop. Asia also; (6) The gymnosperms of Fujian Province is interacting with areas being connected with Fujian Province through Wuyi Mountains and Fujian-Taiwan land bridge, The outcome of coefficient of similarity analysis also indicates that there is closely relationship between gymnospermous flora of Fujian and those of S China, SW China, E China, C China, Taiwan of China.
