| 摘 要： | 对不同干扰条件下杭州西湖山区植被多样性进行了比较,发现随着干扰程度的增加,常绿阔叶林、落叶阔叶林和针阔叶混交林的物种数均是在中度干扰时最高,重度干扰时最低。常绿阔叶林和针阔叶混交林中各层次的均匀度大小为灌木层>藤本层>草本层>乔木层,而落叶阔叶林中各层次的均匀度大小为灌木层>草本层>乔木层>藤本层。3种植被类型中灌木层的优势度都最小,物种数最多,因此灌木层的物种多样性也最高。

| Abstract: | The diversity indexes of the evergreen broad-leaved forest(EBLF),deciduous broad-leaved forest(DBLF) and the needle and broad-leaved mixed forest(NBLMF) in the West Lake Hills Area in Hangzhou in different intensities of disturbance were compared.The results showed the most and the least species occurred at moderate disturbance and severe disturbance in these vegetations,respectively.The species evenness in EBLF and NBLMF was shrub layer>lianas>herd layer>tree layer,while shrub layer>herd layer>tree layer>lianas in DBLF.The smallest dominance and the largest species numbers were occurred shrub layer in these vegetations.It suggested the species diversity in shrub layer were highest. |
