福建青冈林主要种群生态位的研究

Study on the Niche of the Main Tree Population in Cyclobalanopsis chungii Community

对福建青冈群落中12个主要种群的生态位特征进行研究,结果表明,福建青冈、黄瑞木、多穗石栎、栲树是广生态位树种,笔罗子、甜槠、长圆叶鼠刺是狭生态位树种。福建青冈与各种群的生态位相似比例的变化较大。福建青冈群落各种间的竞争并不十分剧烈,群落尚处于不稳定的演替过程中。

The niche characteristics of 12 main tree populations in Cyclobalanopsis chungii forests are analysed by a quantitative method.The results showed that Cyclobalanopsis chungii,Adinandra millettii,Lithocarpus hancei,Castanopsis fargesii were wide niche breadth populations,and Meliosma rigida,Castanopsis eyrei,Itea chinensis var.oblonga were narrow niche breadth ones.The niche similar proportion between Cyclobalanopsis chungii and other populations changed greatly.The inter-population competitions were not intensive and the Cyclobalanopsis chungii community just stayed in a unstable succession stage.
