摘要: 用物种多样性指数(Shnnon-Wienner指数、Simpson指数)、均匀度指数(Pielou)和物种丰富度指数(Margalef指数和Menhinick指数)对广元市7种人工森林群落进行多样性分析.结果表明,植被恢复与重建使生物多样性提高的同时,土壤侵蚀模数比治理前下降了5%;乔、灌、草复层经营对生物多样性与水土保持效益具有同样的贡献;水土保持效益因不同森林群落的生物多样性而异.

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.
