通过对山东省东营市黄河三角洲盐生植物下土壤动物群落结构研究发现,蜱螨目是该地区的主要优势类群,占捕获土壤动物总数量的79.66%;另一优势类群是弹尾目,占捕获土壤动物总数量的13.00%.膜翅目和鞘翅目是常见类群,分别占捕获土壤动物总数量的3.03%和2.07%;其他均为稀有类群.在调查的6个样点中,优势类群弹尾目个体数量受盐度影响明显,分布存在显著差异.黄河三角洲盐生植物下土壤动物多样性以夏季较为丰富,土壤动物多样性与均匀度表现为正相关关系.黄河三角洲盐生植物下土壤动物垂直分布显示:该区土壤动物具有明显的表聚现象.

At the Yellow River Delta (YRD) in Dongying, Shandong, Acari and Collembola were dominant groups, the former accounting for 79.66%and the later for 13.00%. The frequent groups were Hymenoptera and Coleoptera, the former accounting for 3.03% and the later for 2.07%. Then the remnant groups were rare groups. The number distributions of Acari and Collembola were different. The soil fauna in summer being richest in diversity. The index of diversity of the soil fauna in the YRD was correlated with the index of evenness. The vertical distribution of the soil fauna had obvious surface assembly.
