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.
Highlights
Study of biological diversity has long been the concern of the ecology
Community as an important part of biodiversity, species diversity is the very important content in community ecology; altitude is one of the main plant community species composition control mountains natural gradient, elevation gradient change will lead to the change of factors such as temperature, precipitation, light conditions, affecting species distribution
The species diversity of zonal plant communities in western Yunnan was studied and results showed that the density of species decreased with the increasing of altitude gradient [15], Zhang [16] has a consistent conclusion based on Luya Mountain plant community diversity in Shanxi province
Summary
Plant species diversity and species richness is the comprehensive reflection of the uniform distribution, the difference can reflect the characteristics of plant communities in composition, structure, characteristics of spatial and time characteristics, and reflect the plant community [1] [2]. We investigated the vegetation under different elevation gradients in the Cibagou National Nature Reserve, and analyzed species diversity by the commonly analysis method. The aim was to provide some references for the comprehensive management of vegetation, the protection and development of biodiversity in Cibagou Nature Reserve
