Study on Plant Community Diversity in Putang Scenic Resort in Maanshan City of Anhui Province

Ten tree plots in plant community of Putang Scenic Resort were studied.The results showed that there are 143 species of vascular(including varieties),which belong to 101 genera and 62 families.Lindera glauca,Castanea seguinii,Celtis sinensis took up predominant positions,their importance values were 36.82,31.09,24.13 respectively.Plant community of Putang Scenic Resort have relatively high species indexes and relatively even distribution,their Simpson index,Shannon-Winner index and Evenness index average were 15.069,3.16,0.82 respectively.Then,the relationship between species diversity and growth form was studied,the conclusion is that the species richness order was that the shrub layer,herb layer,tree layer.The species richness of shrub showed close relationship with the total species richness of community;the Simpson index and Shannon-Winner index were the highest in the shrub layer,but were in un-regular variance in the tree layer and herb layer.
