摘要:
运用TWINSPAN对山西七里峪茶条槭群落类型进行划分,并采用Patrick指数、Simpson指数、ShannonWiener指数、Alatalo指数研究群落的物种多样性。结果表明:TWINSPAN将茶条槭群落的73个样方划分为10个群丛;各群丛的物种丰富度指数、多样性指数和均匀度指数之间存在差异,群丛Ⅲ和Ⅶ的丰富度指数和多样性指数较高,群丛Ⅰ的多样性指数较低;各群丛乔木层、灌木层和草本层之间的物种多样性也存在差异,多样性指数大致表现为草本层高于灌木层高于乔木层。土壤中的有机质、速效钾、含水量是影响茶条槭群落物种多样性的主要因素。
Abstract:
Based on a survey of 73 community quadrats,TWINSPAN and four indices (Patrick,Simpson,Shannon and Alatalo index) of species diversity were used to analyze differences in richness,evenness and heterogeneity between the communities. The correlation analysis was performed to reveal the relationship between diversity indices and environmental factors. The results showed that Acer ginnala communities were classified into 10 associations. Among 10 associations,there were differences of richness indices,diversity indices and evenness indices. The indices of species diversity of the asso. Ⅲ and Ⅶ were higher,while that of the asso. Ⅰ was lower relatively. The differences of species diversity of arborous layer,shrub layer and herb layer in each association also had occurred. The richness and diversity indices showed similar rule,namely herb layer>shrub layer>arborous layer. The evenness indices of different layer,however,were the other way round. The main factors were physical microenvironmental factors such as organic matter,K+ and water content in soil for the community structure of Acer ginnala.
