Investigation and Study of Rhododendron sutchuenense Ancient Tree Community in Hubei Dalaoling National Nature Reserve
We aim to understand the characteristics of Rhododendron sutchuenense ancient tree community in the Dalaol-ing National Nature Reserve.We studied the species composition,community structure and species diversity of the R.sutchuenense ancient tree community by using quadrat investigation.The results showed that there were 65 species of vas-cular plants existed in the sampling plots,belonging to 34 families and 52 genera,including 29 arbor species belonging to 14 families 21 genera,26 herb species belonging to 15 families 22 genera,7 shrub species species belonging to 7 families 7 gen-era,3 liana species belonging to 2 families 2 genera.R.sutchuenense was the dominant species in the sampling plots,with a total of 334 plants,and 75 ancient trees.The size structure of R.sutchuenense was intact and the population of R.sutchuenense was relatively stable.The vertical structure of the community was obvious,with R.sutchuenense,Indocala-mus tessellatus and Oxalis griffithii as the dominant species in the arbor layer,shrub layer and herb layer respectively.The analysis of the biodiversity of the community showed that the average richness index was the arbor layer＞herb layer＞shrub layer,and the Simpson and Shannon-wiener index were herb layer＞tree layer＞shrub layer.
