【摘要】:采用陷阱诱捕法和网捕法于2016年7月-8月对宁夏温性草原13种不同草原型的甲虫种类和数量分布进行了调查,共获得甲虫标本1591号,分属于10科58种,其中直角通缘步甲Pterostichus gebleri(Dejean)、麻步甲Carabus brandti brandti Faldermann、短翅伪葬步甲Pseudotaphoxenus brevipennis Semenov、甘肃大步甲Carabus gansuensis gansuensis Semenov、暗星步甲Calosoma(Charmosta)lugens Chaudoir和蒙古伪葬步甲Pseudotaphoxenus mongolicus(Jedlicka)为优势种,个体数量分别占总个体数的23.69%、9.68%、9.05%、8.61%、8.30%和6.28%。在种类分布上,固原官厅乡三等长芒草Stipa bungeana Trin.型、同心郭大湾村二等大针茅S.grandis P.Smirn.长芒草型、同心张家塬乡四等大针茅长芒草型、彭阳罗洼乡三等百里香Thymus mongolicus Ronn长芒草型及彭阳孟塬乡四等铁杆蒿Artemisia sacrorum Ledeb.长芒草型等地种类和数量均较多;多样性分析表明,海原月亮山四等苔草Carex.spp.、杂类草Miscellaneous grass型集中性概率指数最大,同心张家山村二等大针茅长芒草型多样性指数和均匀性指数均最大,固原官厅乡三等长芒草型的丰富度指数最高;群落相似性分析显示,固原三营镇三等长芒草大针茅型与同心张家塬乡四等大针茅长芒草型、同心郭大湾村二等大针茅长芒草型相似性系数最高;昆虫对生境指示作用分析表明,胸圆高鳖甲Hypsosoma rotundicolle Fairmaire和弯齿琵甲Blaps(Blaps)femoralis femoralis(Fischer von Waldheim)分别可作为彭阳孟塬乡四等铁杆蒿长芒草型和海原嵩川乡三等苔草杂类草型的指示类群。
