摘 要:无想寺森林公园麻栎次生林群落中立木密集程度因样地不同存在一定的差异,群落垂直结构分为乔木、灌木和草本3个层次,群落中木本植物占优势;群落的植物区系特征具有明显的热带性质,但温带区系成分也占有一定比例;群落的外貌是由小型叶、单叶、纸质叶、非全缘叶为主的落叶高位芽植物所决定的,具有明显的温带向亚热带阔叶林过渡的特点;由麻栎立木结构表明该群落处于旺盛生长期;在演替过程中能够保持落叶阔叶林的稳定结构。The stock density of secondary Quercus acutissima community was varied in different plots and the vertical structure could be divided by arbor, shrub and herb layers. Woody plants dominated in the community. The flora was characterized with obvious tropical nature, but the temperate species occupied a certain proportion. The deciduous phaenerophyte of microphyll, single, herbaceous and non-entire leaf dominated the community, which characterized by the distinct transitional features from the temperate zone to the subtropical zone. The stock structure showed that the community was in vigorous growing stage, and the community could still remain stable deciduous broad-leaved forest in the future succession.
