摘要
在山西庞泉沟自然保护区选取典型森林群落5类,设置15块样地,采用Rao指数和CWM指数计算群落的功能多样性指数,分析了不同森林群落功能多样性指数及其生态学意义。研究结果表明:不同群落类型群落功能Rao指数和CWM指数表现一致,基本排序为:华北落叶松混交林>云杉混交林>油松混交林>阔针混交林>阔叶树混交林,群落内不同层次间排序为:乔木层>灌木层>草本层。群落功能多样性指数与物种多样性指数呈显著正相关,并与群落生产力等功能特性密切相关。
Functional diversity and ecological significance of five different forests were analyzed by the functional diversity indices of Rao and CWM in Pangquangou Natural Reserve in Shanxi. Results showed that the indices of Rao and CWM had the same variation rule in different forest communities that indices of five forest communities ranked as mixed forest of Larix. principis-rupprechtii, mixed forest of picea, mixed forest of P. tabuliformis, mixed forest of coniferous and broad-leaved, mixed forest of broad-leaved and indices of tree layer, shrub layer, herb layer that ranked as arboreal layer, shrub layer, herb layer in forest community. This research also indicated that functional diversity index was positively related with the biodiversity index, and was closely related with the ecological significance such as productivity.
