【摘要】：采用陷阱誘捕法和網(wǎng)捕法于2016年7月-8月對寧夏溫性草原13種不同草原型的甲蟲種類和數(shù)量分布進(jìn)行了調(diào)查,共獲得甲蟲標(biāo)本1591號,分屬于10科58種,其中直角通緣步甲Pterostichus gebleri(Dejean)、麻步甲Carabus brandti brandti Faldermann、短翅偽葬步甲Pseudotaphoxenus brevipennis Semenov、甘肅大步甲Carabus gansuensis gansuensis Semenov、暗星步甲Calosoma(Charmosta)lugens Chaudoir和蒙古偽葬步甲Pseudotaphoxenus mongolicus(Jedlicka)為優(yōu)勢種,個體數(shù)量分別占總個體數(shù)的23.69%、9.68%、9.05%、8.61%、8.30%和6.28%。在種類分布上,固原官廳鄉(xiāng)三等長芒草Stipa bungeana Trin.型、同心郭大灣村二等大針茅S.grandis P.Smirn.長芒草型、同心張家塬鄉(xiāng)四等大針茅長芒草型、彭陽羅洼鄉(xiāng)三等百里香Thymus mongolicus Ronn長芒草型及彭陽孟塬鄉(xiāng)四等鐵桿蒿Artemisia sacrorum Ledeb.長芒草型等地種類和數(shù)量均較多;多樣性分析表明,海原月亮山四等苔草Carex.spp.、雜類草Miscellaneous grass型集中性概率指數(shù)最大,同心張家山村二等大針茅長芒草型多樣性指數(shù)和均勻性指數(shù)均最大,固原官廳鄉(xiāng)三等長芒草型的豐富度指數(shù)最高;群落相似性分析顯示,固原三營鎮(zhèn)三等長芒草大針茅型與同心張家塬鄉(xiāng)四等大針茅長芒草型、同心郭大灣村二等大針茅長芒草型相似性系數(shù)最高;昆蟲對生境指示作用分析表明,胸圓高鱉甲Hypsosoma rotundicolle Fairmaire和彎齒琵甲Blaps(Blaps)femoralis femoralis(Fischer von Waldheim)分別可作為彭陽孟塬鄉(xiāng)四等鐵桿蒿長芒草型和海原嵩川鄉(xiāng)三等苔草雜類草型的指示類群。
