摘要
通过样方调查,对芒萁灌草丛不同恢复阶段的群落特征进行了分析,结果表明,芒萁群落乔木种类较为单一,物种的丰富度,多样性和均匀性都随年龄增加而逐渐增加,群落不同恢复阶段各层物种的相关系数较高,群落年龄结构属于增长型,灌木层-草本层-乔木层的物种多样性依此递减.
Through plot investigation.The study on the community feature of Form.Dicranopteris pedata at different restoration stages showed that:The number of species for Arbor were little in community of Dicranopteris pedata.The species richness,diversity and evenness were gradually increased as ages,and the correlation coefficients of species in each layer at different restoration stages were higher.The age structure of Dicranopteris pedata community were upswing.The species diversity decreases from Shrub,Herb to Arbor layer.
