摘要: 2007年6—9月,对三江平原地区6种不同土地利用生境下步甲群落结构进行调查,共采集步甲标本34种871号,其中淡足青步甲、暗青步甲和圆角梨须步甲分别占总数的19.4%、19.3%和13.2%,共同构成本研究区的优势类群。通过对物种丰富度、多样性指数、均匀度指数等多样性指标进行分析,丰富度在杨树林最高,白桦-蒙古栎林最低;多样性指数和均匀度指数在大豆田最高,杨树林最低。土地利用方式对步甲数量有显著影响(F=2.987,P<0.05),杨树林步甲数量最多,松树林最少;采样时间对步甲数量显著影响(F=8.172,P<0.05),9月步甲数量最多,7月最少。但土地利用方式和采样时间对步甲丰富度,多样性,均匀度没有显著影响。

Abstract: By using pitfall trap, the Carabidae communities in six different land use types including poplar forest, pine forest, birchoak forest, soybean field, and soybean field ridge and ditch in  Sanjiang Plain were investigated from June to September 2007. A total of 871 Carabidaes belonging to 34 species were collected, of which, Chlaenius pallipes, Synuchus orbicollis and Chlaneius tristis  were the dominant groups, accounting for 19.4%, 19.3%, and 13.2%, respectively. The richness index was the highest in poplar forest and the lowest in birchoak forest, while the ShannonWiener index and Pielou index were the highest in soybean farmland and the lowest in poplar forest. Variance analysis showed that land use type and sampling time had significant effects on Carabidae abundance, which was the highest in poplar forest and the lowest in pine forest (F=2.987, P<0.05), and the highest in September and the lowest in July (F=8.172, P<0.05), but had no significant effects on the richness, diversity, and evenness of Carabidae.
