摘要 对莫莫格国家级自然保护区的昆虫进行了系统调查,采用Shannon-Wiener多样性指数(H′)、Simpson优势度集中性指数(D)、Pielou均匀度指数(J′)及PIE种间相遇率对不同生境优势目昆虫进行了比较分析.结果表明:应用4种多样性指数测度6个优势目昆虫总体多样性时,其结果虽有差别,但都显示碱蓬群落的多样性指数值最低.分别对5个优势目的昆虫进行多样性分析,结果表明:直翅目、双翅目、鳞翅目锤角亚目的昆虫在碱蓬群落中多样性指数均为最低;鞘翅目在榆树林群落的多样性指数最低;膜翅目在苔草-小叶樟群落的多样性指数最低.不同目昆虫在不同的群落中分布有差异,表明昆虫对栖息的生境条件具有选择性.探明了莫莫格保护区不同类群昆虫群落的多样性,对未来莫莫格湿地昆虫资源的开发利用和保护提供了理论依据. The insect species in Momoge National Nature Reserve were systematically investigated in the study.Shannon-Wiener's diversity index,Simpson's index,Pielou's evenness and interspecific encounter probability indexes were used to study the insect diversity of the different representative habitats.The results showed there were differences among the 5 orders diversity,and the diversity indexes of Suaeda community were the lowest when analyzing the 6 orders' diversity as a whole.The diversity indexes of the three orders(Lepidoptera,Diptera and Orthoptera) in Suaeda community were the lowest of when analyzing the insect diversity indexes respectively.Coleoptera had the lowest indexes in Elm tree community;and Hymenoptera had the lowest indexes in Carex spp.-Deyeuxia angusrifolia community.It was obvious that insects of different orders had dissimilar optimum habitat selection in heterogenous habitat type.Insect communities' diversity in Momoge protection areas was clarified in the study,and the above results provided theoretical basis for development and protection of insect resources in Momoge wetland protection area.
