Study on Seed Plant Flora of Diaoling Mountain Nature Reserve

Vegetation form and distribution change law in Diaoling Mountain of Yunnan Province were recorded and analyzed from 2014 to 2015 in three species resource surveys based on the method of investigating typical sample plots and routine. Result showed that there were 112 families, 355genera, 655 species of seed plants flora in the region, and the proportion of families, genus and species was different from Ailao Mountain, but same as Zixi Mountain. While middle and small sized genus which contained 1-5 species accounted for 9436%. At the families level, pantropic component accounted for high proportion in the reserve; at the genus level, temperate component was next to tropic component. Therefore, the flora of reserve was characterized by the transitional category from tropical to temperate zones. In addition, there were four endemic families of East Asian and two endemic genera of China in the reserve, so its endemism was relatively low compared with the other areas in central Yunnan.
