Abstract:There are variety of seed plant in Wulingyuan.Generally, there are 171 families, 742 genera and 1468 species(including long-term domesticated plants),of which the gymnosperms are 8 families. 24 genera and 39 species; while the angiosperms are 163 families, 718 genera and 1429 species. In this thesis, we have conducted deep and accurate analyses and count on the characteristics of the flora of the seed plants of Wulingyuan, and the analyses and count are from different standards of the families, the genus and the species.According to the results, we find that the components of seed plants mainly belong to north temperate distribution-type,and the genera number is 389. Then the tropical distribution-type isnext to it, with 289 genera. In addition, some special distribution in East Asia and in China is also one of the very important ingredient of the flora, and the genera number is 139. From this point of view, we can draw a conclusion that the flora of this region not only contains abundant tropical and temperate components,but also represents the important role of the flore of Wulingyuan in Middle China.Furthermore,there are also lots of rare, precious, ancient, and primitive plant components.
