研究郑州市公园绿地土壤动物的群落组成、垂直分布及多样性,以期为公园绿地土壤动物多样性保护及土壤生态环境的改善提供科学依据。结果表明,郑州市公园绿地土壤动物分属于4门9纲26目;小杆目、蜱螨目、膜翅目、弹尾目为优势类群,其动物数量占总动物数的83.26%;颤蚓目、姬马陆目、蜘蛛目、鞘翅目、双尾目、缨翅目为常见类群,其动物数量占总动物数的14.60%;稀有类群动物数量占总动物数的2.14%;公园绿地土壤动物群落垂直分布非常明显,随着土层深度增加,土壤动物的类群数和个体数逐渐减少,表现出较强的表聚性,且土壤动物优势度指数升高,多样性指数降低。
The community structure and vertical change of soil animal in park green space in Zhengzhou were investigated to provide a scientific basis for the protection of soil animal diversity and improvement of the soil ecological environment of urban park. The results showed that the soil animals belonged to 4phylums,9 classes and 26 orders. The dominant community included Rhabditida,Acarina,Hymenoptera and Collembolan,their number accounted for 83. 26% of total animal number; the common population included Tubificida,Julida,Araneae,Coleopteran,Diplura and Thysanoptera,their number accounted for14. 60% of total animal number; the rare population number accounted for 2. 14% of total animal number. The vertical distribution of soil animal community was obvious. With the increase of soil depth,the species number and individual number of soil animal decreased,showing a strong table cohesion; the dominance index of soil animal increased; the diversity index decreased.
