The plant species diversity within the artificial coniferous community in Baishanzu Nature Reserve

The species richness index,species diversity index and community evenness in different plots and layers of the artificial coniferous community in Baishanzu Nature Reserve,Zhejiang Province were analysed by using the adjacent grid method.The result showed that the species richness(19) and species diversity index of woody plants were obviously bigger than those of herbs.Their community evenness had slightly different significance.In the vertical structure of community,the species richness and species diversity index of shrub layer were obviously bigger than those of the tree layer and the herb layer.It was not very different from those between tree layer,shrub layer and herb layer.
