摘 要:试验对位于山东省无棣县北部的黄河三角洲贝壳堤岛,逐月进行分层(上、中、下3层)取样研究该区跳虫群落结构,共获得各类跳虫标本7 461头,隶属于弹尾纲4目7科17属。结果表明,优势类群为棘跳属(Onychiurus)和符跳属(Folsomia)两者之和占总捕获个体数量的79.25%;常见类群为球角跳属(Hypogastrura),疣跳属(Neanura),奇跳属(Xenylla)和等节跳属(Isotoma),占总捕获个体数量的15.91%;其他11个属为稀有类群,仅占总捕获个体数量的4.84%。跳虫群落的Margalef丰富度指数、Shannon-Weiner多样性指数和Pielou均匀度指数的变化规律一致,Simpson优势度指数与Pielou均匀度指数的变化规律相反。Shannon-Weiner多样性指数(H)的月份动态为8月>7月>9月>10月>5月>6月。From May to October of 2008 by using a sampling method,the soil collembolans communities were investigated at shell island of the Yellow River Delta(YRD) in the north of Wudi,Shandong Province.Totally 7 461 soil collembolans individuals belonged to 17 genus,7 families and 4 orders were obtained in total samplings,among which Onychiurus and Folsomia were dominant groups and their amount reached 79.25% of the total.Hypogastrura,Neanura,Xenylla and Isotoma were the frequent groups and their amount reached 15.91% of the total.And then,the remnant groups were rare groups.The changes of Shannon-Weiner diversity index,Margalef richness index and Pielou evenness index were similar,contrary to that of Simpson dominance index.The monthly dynamics of ShannonWeiner diversity index was AugustJulySeptemberOctoberMayJune.
