Studies on Flora and Geographical Distribution of Gymnosperm in Wuyi Mountains,Fujian Province,China

The geographical distribution,floristic characteristics,and species differentiation of gymnosperm in Wuyi Mountains,Fujian Province,were studied based on field investigation.The results showed that Wuyi Mountains of Fujian was a core region of Huangshan-Wuyi Mountains centers,there were 39 species of gymnosperms,belonging to 10 families and 24 genera.The geographical distribution patterns belonged to mid-altitude bulge type along altitude.Flora of gymnosperm had notable subtropical mountainous characteristic,the proportion of tropical areal-type decreased with the increment of latitude,while the proportion of temperate and endemic to China areal-types increased.The phylogenetic differentiation intensity of gymnosperm decreased from northern to southern of Wuyi Mountains.
