福建武夷山脉裸子植物区系与地理分布的研究

通过野外实地考察，研究了福建武夷山脉裸子植物区系与地理分布及种系分化特点。结果表明：福建武夷山脉是中国裸子植物多样性中心之黄山-武夷山脉中心的核心区域，裸子植物共有10科24属39种。其地理分布呈中间海拔膨胀型。裸子植物的区系具亚热带性质，随纬度升高热带分布的比例呈下降趋势，而温带分布和中国特有分布的比例则呈上升趋势。裸子植物种系分化强度表现出南低北高的变化特点。

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 latitude. Flora of gymnosperm had notable subtropical mountainous characteristic, the proportion of tropical areal-type decreased with the increment of altitude, 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.
