Abstract: The species diversity of seven forest communities in Guangyuan city was measured with diversity index (Shannon-Wienner index,Simpson index),evenness index(Pielou) and richness index(Margalef index,Menhinick index).The results showed that vegetation restoration make it possible for the increase of biodiversity and the modulus of soil erosion declined by 45%.Mixed forest is important for biodiversity as well as for soil and water conservation.Benefits of soil and water conservation are different in different forest communities which depend on the species diversity.
