广东八宝山常绿阔叶林物种多样性分析

    SPECIES DlVERSITY OF EVERGREEN BROADLEAVED FOREST IN BABAOSHAN NATURE RESERVE,GUANGDONG

    • 摘要: 研究了广东八宝山自然保护区常绿阔叶林26个群丛的物种多样性,并对其生态学意义作了简要的分析。结果表明,处于中亚热带的八宝山常绿阔叶林物种多样性指数(Shannon-Wie-ner指数)在2.02~4.43之间;物种均匀度在0.51~0.96之间;生态优势度在0.06~0.24之间。八宝山的低山常绿阔叶林物种多样性指数与南亚热带常绿阔叶林的相近,其值为3.22~4.43。还分析了物种多样性与生境条件的关系。

       

      Abstract: species diversity of evergreen broadleaved forest in Babaoshan Nature Reserve,Guangdong,was studied by computing the species diversity index, species evennessand ecological dominance of 26 associations.The species diversity index(Shan-non-Wiener Index) ranged from 2.02 to 4.43,species evenness from 0.54 to 0.24and ecological dominance from 0.06 to 0.17.The species diversity index of low montaneevergreen broadleaved forest in this region,which ranged from 3.22 to 4.43,was simi-lar to that of the lower subtropical evergreen broadleaved forest.The relationship be-tween species diversity and the habitat is also analyzed in this paper.
