Change of component structure of shrubland in Tiantong region,Zhejiang Province under different treatments

Abstract

Abstract: The community diversity of shrubland in Tiantong region,Zhejiang Province was measured by using the methods of species of abundance,Simpson index,Shannon-Wiener index and community evenness index.The beta diversity between before treatments and after treatments was also measured by applying β diversity index and similarity index.In addition,the changes of species composition and their importance values in the shrubland were analyzed.The results showed that whether in the first or second group of plots,the species composition and their importance values changed in varying degree.Compared with plots before treatments,the species diversity of shrub layer of experimented plots decreased while ecological dominance and community evenness were improved.By means of comparing beta diversity and similarity index,the results also showed that the species composition of experimented plots have changed to various extent.

Key words: Shrubland, Community, Species composition, Tiantong, N accumulation, N translocation, seed quality, oil peony
