摘  要：
为研究毛竹林扩张对植物多样性的影响,在浙江天目山国家级自然保护区内,采用样方调查法对毛竹林、常绿阔叶林、毛竹-常绿阔叶林、针叶林、毛竹-针叶林、针阔混交林、毛竹-针阔混交林等7种群落进行调查,分析毛竹扩张对自然保护区植物群落立木数、不同类型不同层次的物种丰富度、多样性指数及均匀度指数的影响。结果表明:毛竹林的立竹度为3700株·hm-2,毛竹扩散到其他森林类型,均造成其他树种立木数的降低。受毛竹扩张的影响,常绿阔叶林、针叶林、针阔混交林植物群落的乔木层物种丰富度、多样性指数及均匀度有减小的趋势。灌木层中,由于受毛竹扩张的影响,常绿阔叶林和针叶林的物种丰富度、多样性指数及均匀度增大。草本层中,常绿阔叶林和针叶林的物种丰富度、多样性指数及均匀度基本未受毛竹扩张的影响。

摘  要：
By sampling method,we studied the effects of Phyllostachys pubescens forest expansion on biodiversity in Tianmu Mountain National Nature Reserve in seven communities of the P. pubescens forest,the broad-leaved evergreen forest,the P. pubescens broad-leaved evergreen forest,the coniferous forest,the P. pubescens coniferous forest,the mixed broadleafconifer forest,and the P. pubescens mixed broadleaf-conifer forest. The number of P. pubescens was 3 700 tree·hm-2. The number of other species decreased with the expansion of P. pubescens forest for the three communities. The species richness,species diversity index and evenness of plant communities decreased with the expansion of P. pubescens forest. Three indices of species diversity of shrub layer of the broad-leaved evergreen forest and the coniferous forest were higher than those of the corresponding communities which were expanded by P. pubescens forest. The species richness,species diversity index and evenness of herbaceous plant communities were almost unchanged along with the expansion of P. pubescens forest.
