千岛湖生境片断化对苔藓植物多样性的影响

Effect of Habitat Fragmentation on Bryophytes Diversity in the Thousand-Island Lake Region

  • 摘要: 选取浙江千岛湖东南湖区的10个岛屿和1个半岛,详细研究了苔藓植物组成及生境片断化对其多样性的影响。研究结果表明:该区域有苔藓植物37科71属129种,其中浙江新记录3种。群落类型主要包括土生群落、石生群落和树生群落。苔藓植物区系以东亚成分为主,其次为北温带成分和热带亚洲分布,分别占总种数的39.45%、20.18%和18.35%,说明该地区苔藓植物区系具有典型的东亚特征。岛屿面积对苔藓植物分布影响结果显示:不受岛屿面积影响的苔藓植物有29种,受岛屿面积影响的苔藓植物有58种;各岛屿苔藓植物物种数与岛屿累加面积存在明显正相关。

     

    Abstract: Based on an investigation of bryophytes on ten islands and one peninsula of the southeastern sub-region of the Thousand-Island Lake,the composition of bryophytes and the effects of habitat fragmentation on their diversity were studied.The results showed 129 species belonging to 71 genera and 37 families,among which 3 species were new to Zhejiang province.Geophytia,petrophytia and epixylophytia were dominant bryophyte communities.The bryoflora of the Thousand-Island Lake was characterized by East Asia elements represented by 39.45% of the entire species,followed by North Temperate elements and Tropical Asia elements which accounted for 20.18% and 18.35%,respectively.The distribution of 58 bryophyte species was affected by island area,while 29 species was unaffected.The relationship between island size and bryophyte richness showed a positive correlation.
