钱江源国家公园昆虫物种组成及其多样性分析

Composition and Diversity of Insect in Qianjiangyuan National Park

2016年5月—2018年11月,利用网捕法、马氏网诱捕法、灯诱法、黄盘诱捕法、陷阱法对钱江源国家公园进行了昆虫资源调查,并分别从昆虫的物种组成、群落相似性和多样性等方面对保护区昆虫多样性进行分析。结果表明,钱江源国家公园昆虫共有2014种,隶属24目275科1244属;优势类群鳞翅目Lepidoptera、膜翅目Hymenoptera、鞘翅目Coleoptera、双翅目Diptera、半翅目Hemiptera的科数分别占总科数的17.45%、14.91%、12.36%、11.27%和10.55%,其种数分别占总种数的25.93%、15.6%、10.53%、23.0%和8.49%;拥有天敌昆虫、药用昆虫和观赏昆虫累计73科263种,占昆虫总种数的13.07%;多样性分析结果显示,钱江源国家公园的昆虫Shannon-Wiener多样性指数、Simpson优势度指数、Margalef丰富度指数的变化趋势一致,表明钱江源国家公园科昆虫群落具有较高的稳定性。研究结果为钱江源国家公园内的昆虫资源的保护和利用、生物研究提供重要数据。

During May 2016 and November 2018,investigation of insect resources was conducted by different methods in Qianjiangyuan National Park,Zhejiang province.The result demonstrated that there were 2014 species belonging to 1244 genera,275 families and 24 orders.Families of Lepidoptera,Hymenoptera,Coleoptera,Diptera and Hemiptera,accounted for 17.45%,14.91%,12.36%,11.27%and 10.55%of the total ones,and their species occupied 25.93%,15.6%,10.53%,23.0%and 8.49%of the ones in the Park.The natural enemy insect,medicinal insect and ornamental insect had 263 species of 73 families,accounting for 13.07%of the total species.Analysis showed that Shannon-Wiener diversity index,Simpson dominance index and Margalef richness index had similar changes,revealing that the insect community structure in Qianjiangyuan National Park was stable.
