摘　　要：通过对南京牛首山森林公园苦槠次生林典型群落样地的调查,分析了该群落的植物区系特点、群落组成、群落层次结构特征以及演替趋势。该群落的植物区系具有明显的热带性质,群落中木本植物占绝对优势;层次分明,有乔木、灌木和草本3个层次。在未来的演替中,该群落的落叶物种将会逐渐减少,最终会演替为稳定的常绿阔叶林结构。The floristic characteristics, community composition, spatial structure characteristics and succession tendency were analyzed in terms of the data collected from plots of Castanopsis sclerophylla community of the secondary forest in Mount Niushou Forest Park, Nanjing City. The flora is characterized by obvious tropical nature, and woody plants are dominated in the community with distinct layers of arbor, shrub and herb. In the future succession, the deciduous species will reduce gradually, and the community will finally succeed to an evergreen broad-leaved forest.
