| 摘 要： | 应用物种多样性指数(Shannon-Wiener指数、Simpson指数)、均匀度指数(Pielou)和物种丰富度指数对重庆四面山地区5种人工水土保持林群落进行多样性分析.结果显示:(1)5种人工林群落以枫香+木荷+石栎+香樟+灌木混交林的物种多样性最为丰富,纯杉木林最次.(2)各多样性指数在不同群落间的变化以乔木层的枫香+木荷+石栎+香樟+灌木混交林、灌木层的石栎+木荷混交林、草本层的纯杉木林等的生物多样性最为丰富.(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的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一灌结合混交林模式,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: | The species diversity of five different deposition model plantations in Chongqing Simian Mountain was measured with diversity index(Shannon-Wiener index,Simpson index),evenness index(Pielou) and richness index.The results showed that Liquidambar formosana+Schima superba+Lithocarpus glaber+Cinnamomum camphora+shrub mixed forest had the richest species diversity among the five type of plantations.Cunninghamia lanceolata was in the lowest.The change of every diversity index about Liquidambar formosana+Schima s... |
