The semi-humid evergreen broad-leaved forest is an important vegetation type in vertical zone of the Mts. Wuliangshan, which is on the edge of extinction. Based on the analysis of the disposition in vertical structure of 177 dominant and frequent species in the forest and in other areas of the mountains,it shows that there are only Tropical Asia,Sino-Himalayan and Chinese endemic elements appearing in all the all the synusiae from the canopy to the ground layer, including A,B and C tree layers, shrub layer ground layer and inter-layers. It is floristically subtro0pical in the forest rather than temperate according to a further analysis of distributions on Chinese endemic species. In the semi-humid evergreen broad- leaved forest zones there are four types of common deciduous broad-leaved forests. They are Alnus nepalensis forest, Juglans sigillata forest, Populus bonatii forest and Leucosceptrum canum forest respectively. They are secondary forests after the original vegetation was destroied. It is necessary to protect the secondary forests because we do not know what stages they are belonging to in ecological succession. It may be an ideal places for studying the secondary succession and restoration ecology. The semi-humid evergreen broad-leaved forests of Mts. Wuliangshan are of obvious significance in biodiversity conservation because of its important characters and the location harbpring many endemic and endangered taxa.
