摘要
通过对永州不同生境设立5个样区进行取样调查,共获得土壤动物2024头,隶属于5门、10纲、31目、111科、共152种。其中垫刃目、弹尾目、蜱螨目属于优势类群;矛线目、膜翅目等14个目属于常见类群,构成了永州土壤动物的主体。不同生境中土壤动物的种类和个体数量都有一定的差异,苗圃和杉树林远远大于其它3个生境。土壤动物的垂直分层也比较明显,种类和个体数量随着土壤层次的加深而减少,具有明显的表聚性。对各生境的密度—类群指数DG、丰富度指数D、多样性指数H、优势度指数C、均匀性指数E和相似性系数进行分析,结果表明,植被类型、土壤有机质含量是影响土壤动物群落结构的主要生态因子。
2024 individuals of 152 species are captured by sampling investigation on soil animals in purple soil of 5 kinds of different habitat in Yongzhou Area, Hunan, and belong to 5 sorts,10 class, 31 orders and 111 families. Of which Tylenchida,Dorylaimida and Acaraina are the dominant orders, 14 orders such as Dorylaimida,Hymenopteraetc are the common ones and these two parts of orders form the main bodies of soil animals in Calcarleous Shale of Yongzhou Area. There are certainly differences of animal varieties and quantities in different soils of habitats that animal individuals of nursery, pine-forest are obviously more than that of the other three soils of habitats. And also there are evidently upright delamination, of them that mainly live in the topsoil layer because their varieties and amounts decrease with the increasement of soil animals gradations. The results show that vegetation types and organic contents are main ecological factors that influence on soil animal community structure through analyzing the indexes of destiny-group（DG）, variety（D）, diversity（H）, dominance（C）, evenness（E） and comparability coefficient on different habitats.
