| Abstract: | Based on the investigating the natural community of Taxus chinensis var.mairei,Simian Mountain,Chongqing,the results showed this community is dominated by invasion of Neosinocalamus affinis and can be divided into 1 formation groups（Neosinocalamus affinis forest）,3 associations.The community is formed of arbor,shrub and herb layers.In this plantation,3 layers demonstrate a declining trend in richness and diversity indices,shrub layerherb layerarbor layer.Neosinocalamus affinis dominates in the species of arbor layer while Taxus chinensis var.mairei in shrub layer act as the characteristic species of the community. |
