| 摘 要： | 本文对内蒙古巴盟草原昆虫群落结构及其多样性进行了初步研究。1、初步统计,共采到昆虫8目51科119种1772头。植食性种类占74.8％,捕食性和寄生性种类占21.8％,其它种类占3.4％。不同草场类型昆虫群落组成不同。2、应用 Shannon-Wiener 多样性指数分析,昆虫群落多样性指数以荒漠草原最高,草旬最低。3、通过 Mountford 相似性指数分析,荒漠草原中锦鸡儿—针茅+冷蒿草场与锦鸡儿—沙蒿草场昆虫群落间的相似性指数最高,草甸与其它草场昆虫群落间的相似性指数都较低。

| Abstract: | This paper,Reported the stricture and diversity of grassland insectcommunity in Bameng,Inner Mongolia.1.A total number of 1772 insects were collected,including 8 orders,51 families and 119 species.Herbiorous species took74.8%,pradutary andparasitic species took21.8%,and other species took 3.4%.The componentsof insect communities in various types of grassland varied.2.By the methed of Shannon-wiener Diversity Index,the diversity of insect community was highest at desert grassland,and lowerest at meadow.3.By the methed of Mountford Similarity Index,the Insect communityimilarity between Caragana spp.-Stipa spp.+Artemisia frigida steppe andCaragana spp.-Artemiscamordosia steppewas highest,and were lower betweenthe meadow and other types of grassland. |
