| 摘 要： | 以重庆四面山地区5种人工林群落调查资料为基础,用物种多样性指数（Shannon-Wienner指数、Simpson指数）、均匀度指数（Pielou）和物种丰富度指数对这几种人工林群落进行多样性分析。结果表明：（1）5种人工林群落物种多样性排序为：枫香＋木荷＋石栎＋香樟-灌木混交林〉石栎＋木荷混交林〉杉木＋马尾松＋木荷混交林〉杉木＋马尾松混交林〉杉木纯林;（2）多样性指数在不同群落间的变化幅度均为草本层〉灌木层〉乔木层。且乔木层以枫香＋木荷＋石栎＋香樟-灌木混交林的生物多样性最高;灌木层以石栎＋木荷混交林的生物多样性最高;草本层以杉木纯林的生物多样性最高;（3）不同林型的物种多样性不同,其生态效益、环境效益也有较大差异。建议在四面山地区以及类似生态区,今后退耕还林过程中选择以常绿阔叶林和针阔混交林为主的乔-灌结合混交林模式,以提高人工林群落的物种多样性,实现理想的水土保持林功能。

| Abstract: | Based on the data of five different forest communities in Chongqing Simian Mountain,the species diversity was measured with diversity index(Shannon-Wiener index,Simpson index),evenness index(Pielou) and richness index.The results showed :(1) The species diversity of these five different forest communities were in the following order: Deutzia scabra Thunb +Schima superba+Lithocarpus glaber+Cinnamomum camphora > Lithocarpus glaber +Schima superba > Cunninghamia lanceolata+Pinus massoniana+Schima superba > Cun... |
