| 摘 要： | 在调查南京牛首山森林公园的南京椴天然次生林典型群落样地基础上,分析了该群落的植物区系特点、群落组成及其特征、群落的层次结构特征以及演替趋势。研究表明,该群落的植物区系特征具有一定的热带性质,温带区系成分占相当的比例。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。南京椴林在演替过程中能够保持落叶阔叶林的稳定结构,但有人工毛竹林种群侵入该群落,若不及时清除,将最终对南京椴林的顺行演替产生威胁。

| Abstract: | Based on the data collected from plots of Tilia miqueliana community,the natural secondary forest in Nanjing Mt.Niushou Forest Park,the floristic composition and characteristics,composition and features,spatial structure and succession tendency were analyzed.The flora was characterized with obvious tropical nature,but the temperate floristic elements occupied a certain proportion.The xylophyte dominated in the community,which was divided into three distinct layers: tree,shrub and herb layers.The community could still remain the stable structure features of deciduous broad-leaved forest,but the plantation of Phyllostachys edulis,which has invaded the community,would threaten the progressive succession of T.miqueliana if without being cut artificially. |
