摘要
蝴蝶资源状况能够敏感地反映出特定区域的环境质量,特别是气候及植物群落的变化情况,因此被作为区域生物多样性的重要评价指标.本研究针对新疆夏尔希里自然保护区山地草原带的蝶类物种组成及其多样性进行了研究.结果表明:山地草原带蝴蝶有30种,分属6科24属;粉蝶科(Pieridae)、蛱蝶科(Nymphalidae)、眼蝶科(Satyridae)属种资源比例占优,是山地草原带的主体蝴蝶类群;另外国家二级保护物种:阿波罗绢蝶(Parnassius apollo(L.))种群数量在调查区也较大;区系分析表明:山地草原带蝴蝶有21种为古北区特有种,占70%,其余9种为广布种,占30%,未发现东洋种.生物多样性分析表明:粉蝶科的物种丰富度、多样性指数最高,在山地草原带蝴蝶群落中占据优势地位;蛱蝶科的均匀度指数最高,在群落分布中占优.对山地草原带蝴蝶群落进行多样性分析与区系分析,摸清夏尔希里保护区垂直分布带蝴蝶生物多样性和分布现状,为补充和完善我国深入开展全球气候变化背景下的生物多样性保护工作提供重要的本底调查资料.
The status of butterfly resources could sensitively reflect ecological conditions of a particular region,especially changes of plant communities and climate.Thus,it is regarded as an important indicator of regional biodiversity.In this study,we investigated the composition and biodiversity of butterfly resources in Xarxili Nature Reserve.Thirty butterfly species collected from mountain steppe,belonging to 24 genera from six families of Lepidoptera.We noticed that Pieridae,Nymphalidae,and Satyridae are the first three biggest families,the species and genera of which dominate the quantity of specimens.In addition,we noticed that the population of Parnassius apollo （L.）,a national protected animal species （Ⅱ）,is relatively large.The results of fauna analysis show that 70% （21 of 30） collected butterfly species are endemic species of Palearctic zoogeographic region.The other nine species are distributed in both of Palearctic and Oriental zoogeographic regions.In this study,we did not collected Oriental species.Biodiversity analysis shows the family Pieridae dominates the species richness and diversity in the butterfly community of the nature reserve.The evenness index of family Nymphalidae is the highest among all of the six lepidopterous families.We analyzed the biodiversity and fauna of butterfly communities in mountain steppe.The results would be helpful to reveal the biodiversity and distribution of butterflies in Xarxili Nature Reserve.In addition,our investigation increases the fundamental information to improve biodiversity conservation in the context of global climate change.
