研究森林群落种类组成的数量综合特征,以期为揭示森林群落结构规律、营建以及保护或利用多功能的森林生态系统提供依据.用3个特征指标数值综合为重要值的定量方法,分层测定亚热带常绿阔叶林各物种在群落组成中的地位和作用.结果表明:经过顺向演替,中亚热带常绿阔叶林的种类组成比较丰富,在1000m2左右的3个样地内有乔木22～30种.乔木层的优势种主要由壳斗科、樟科、木兰科、槭树科等常绿树种所组成,大多为珍贵的用材树种和庭园绿化树种.乔木层中含有常绿、半常绿、落叶3个层片,攀援或附生多种层间植物,已形成多层的立体群落结构,表现出向更高阶段演替的外貌特征.
In order to reveal the regularity of forest community structure, construction and protection or utilization of multi-functional forest ecosystem, the quantitative characteristics of the species composition of the forest community were studied to provide the basis for quantitative analysis of three sub-tropical regions Evergreen broad-leaved forest in the community composition of the status and role of the results showed that: through the succession succession, the species composition of the evergreen broad-leaved forest in the subtropical rich, in about 1000m2 3 plots of trees with 22 ~ 30 species.The dominant species of the arbor layer is mainly composed of evergreen species such as Fagaceae, Lauraceae, Magnoliaceae, Maple Branch, etc., mostly of precious timber species and landscaping tree species.The tree layer contains evergreen, Green and deciduous three layers, climbing or epiphytic multiple interpland plants, has formed a multi-layer three-dimensional community structure, showing the appearance of a higher stage of succession.
