摘要/Abstract

摘要： 采用物种丰富度、Simpson指数、Shannon-Wiener指数、群落均匀度指数研究浙江天童灌丛群落在人工处理下群落的α多样性动态特征;采用β多样性指数和相似性系数测定该区灌丛群落在处理后的群落间多样性的变化.此外,还分析了实验样地及对照样地在处理前后的种类组成及其重要值的变化.结果表明,除对照样地外,各实验样地的种类组成及其重要值都有不同程度的改变;与处理前相比,实验样地灌木层的物种多样性有所减少,但生态优势度及群落均匀度有所提高.β多样性的研究结果同样表明在实验处理措施下各实验样地的种类组成已经发生了一定的变化.

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.
