    摘要:

    测算了南岭国家级自然保护区主要天然林的物种多样性指数、物种均匀度和优势度,并对其生态学意义作了简要分析。结果表明,处于中亚热带的广东南岭天然林物种多样性指数在2.90 ̄5.34之间;物种均匀度在0.56 ̄0.87之间;生态优势度在0.05 ̄0.25之间。南岭天然林物种多样性指数依群落类型不同而异,其变化表现为由山地针叶林→山地针阔叶混交林→山地常绿阔叶林→低山丘陵常绿阔叶林递增。还分析了物种多样性

    Abstract:

    Species diversity of the natural forest communities in Nanling National Nature Reserve,Guangdong, was studied by computing the species diversity indices, species evenness and ecologcal dominance of 9 formations .The species diversity indices (Shannon-Wiener Index)ranged from 2.90 to 5.34 ,species evenness from 0.56 to 0.87 and ecological dominance from 0.05 to 0.25. The differences of species diversity indices became larger with forest types from montane coniferous forests to montane coniferous and broadleaved mixed forests, to hilly and low mountainous evergreen broadleaved forests. The relationships between species diversity,habitat and community stability were also analysed in this paper.
