摘要:
大蜀山短毛椴(Tilia breviradiata)林是江淮丘陵地区残存的典型落叶阔叶林,是经砍伐和火烧等破坏后恢复形成的次生林类型,也是重要的地带性植被。基于详细的群落学调查,分析了群落的植物组成、生活型特征、层次结构、群落性质以及演替趋势。结果表明,群落内共有维管束植物42科72属81种,单种科和单种属较多。群落区系地理成分较为复杂,具有一定的温带性质,同时热带成分也占有相当大的比例。群落垂直空间分化明显,可分为乔木层、灌木层和草本层3个层次,层外植物丰富。群落生活型组成、叶性质、优势种群径级结构以及重要值分析体现了较为成熟的北亚热带落叶阔叶林特征,群落处于次生演替系列中的顶极阶段。优势种群短毛椴趋于成熟阶段,演替较为激烈,天然更新较为缺乏。作为合肥市区内宝贵的乡土物种基因库和资源库,该残存落叶阔叶林在区域生物多样性的保护中具有重要的价值。
Abstract:
Natural secondary Tilia breviradiata deciduous broadleaf forest in Dashushan is one of the main secondary forests in the hill terrain between the Yangtze and Huaihe river, which is formed by the restoration after clearcutting or fire. It is also the important zonal vegetation of Hefei city. Based on the data collected from plots of Tilia breviradiata community, the floristic composition and characteristics, composition and features, structure and succession tendency were analyzed. The analysis of floristic geographical elements indicated that the temperate elements were dominant but tropical affinities also existed in the community. The xylophyte dominated in the community, which was divided into three distinct layers: tree, shrub and herb layers, species of inter layer plants were rich. The statistics of community features, life fom, mean DBH, and important value showed that the forest was deciduous broadleaved forest in the subzone of the northern subtropic. Analysis on the structure of community indicated that T.breviradiata was in the maturing stage and in short of natural regeneration, succession was intense.
