摘要：通过在广东南岭自然保护区最高峰——石坑崆山顶矮林建立样地,对石坑崆山顶矮林群落的物种组成、区系成分、群落外貌以及结构特征等进行了研究,结果表明:在4块样地中,计有维管束植物有(10±1.41)科,(14.5±2.08)属,(21.25±6.18)种;该群落区系地理成分主要以热带区系成分为主,且带有温带成分;具有明显的亚热带常绿阔叶林特征。群落生活型谱中以高位芽植物为主,但地上芽植物也占有一定比率,具有一些热带植物群落特征;该群落种群总体上为增长种群。
To understand the species and floral composition, forest structure, plant diversity and coenological characteristics of the montane dwarf forest community in Nanling National Nature Reserve,Guangdong Province,four 20m × 20m sampling plots located from 1700 to 1900m of elevation were stablished. The results showed that, total number of plant species in the communities was 21.25±6.18, representing 14.5±2.08genera and 10±1.41families in four plots. The floral composition of these communities can be divided into 9 floral types. Among those floral tropic distributions are dominant, and with temperate elements. The vertical structure is simple, which only can be divided into tree layer, shrub layer and herb layer. Phanerophyte is dominant in fife-form spectrums, but on the ground also holds a certain percentage of chamaephytes, which has some characteristics of tropical plant communities. The analysis of age structure shows that the population in the whole community is growing population.
