The species diversity of evergreen broad-leaved tree communities in Dagangshan mountains was studied in this paper.The distribution trends of species richness indices,species diversity indices and species evenness indices along the community gradient were almost the same.They reflected the different species composition of different plant communities.The species richness indices of the shrub layer were higher than those of both the tree and herb layers.The species diversity indices of the tree layer were lower than those of the shrub and herb layers.The species evenness indices of the shrub layer were higher than those of both the tree and herb layers.The species richness indices and diversity indices of the plant communities that distributed at both the high and low altitudes were higher than those of the plant communities at the middle altitude.The plant communities at the middle altitude had lower species evenness indices mostly,but higher values occurred in the plant communities at all the altitudes.
