ABSTRACT

The forest community diversity along the altitudinal gradient was analyzed in the Cibagou National Nature Reserve. Results showed that the forest types of Cibagou Gorge could be divided into six types: Castanopsis hystrix forest; camphor and acer mixed forest, blue Japanese oak broad-leaved mixed forest, blue Japanese oak forest, Populus simonii mixed forest; Quercus aquifolioides forest. The total coverage of undergrowth vegetation altitude was the lowest at 1749 m, only 30%, and plant species numbers in the sample was only 5. The total coverage of the plant was the highest at 2327 m altitude, the value was 95%, and the number of species in experiment plot was 14. The species richness of Margalef increased first and then decreased with the increase of altitude gradient at 1749 m to 2880 m, and the Shannon-wiener species diversity index increased, but the difference was not significant, Pielou species evenness and Sheldon species evenness index decreased first and then increased with altitude.
