| 摘 要： | 采用样地调查法,分析安徽皇藏峪自然保护区天然南京椴(Tilia miqueliana)的群落特征。结果表明,南京椴群落有种子49种,隶属于31科44属,地理成分较为简单,主要由温带和热带区系成分组成,并有一定的温带性质和明显的过渡性特征。群落中高位芽植物最多,占67.35%;叶级以小型叶为主,占51.02%;叶形以单叶为主,占79.69%。群落可分为乔木层、灌木层和草本层,乔木层可分为2个亚层;乔木层优势种为南京椴,重要值高达106.87;并有较为丰富的层间植物。南京椴群落物种多样性大小依次为灌木层草本层乔木层。群落中南京椴有一定的天然更新,但缺乏幼树,在群落中处于很不稳定的地位。
