2010年3月—4月对淮南市八公山区4种生境土壤动物进行了调查,获得各类土壤动物1965只,隶属4门12纲27目。其中优势类群为膜翅目和近孔寡毛目,常见类群为等足目、鞘翅目幼虫、鞘翅目成虫、柄眼目、鳞翅目幼虫、蜘蛛目和山蛩目,其余类群为稀有类群。研究结果表明:植被类型对土壤动物群落的结构特征有一定影响,不同植被条件下土壤动物个体及群落类群数存在差异。土壤动物多样性与均匀度指数呈正相关,与优势度呈负相关。4种生境的土壤动物群落之间都达到了中等相似水平。从土壤动物群落数量的垂直分布来看,0 cm~5 cm土壤层数量最大,有明显的表聚现象。
From March to April in 2010, 4 habitats of soil animals were surveyed in Habitat of Baigong Mountain, Huainan City, and 1965 soil animals of all kinds were obtained, belonging to 4 groups of 12 classes and 27 orders. Among them, the dominant groups were Hymenoptera and Morphidae. The common groups were Isopoda, Coleoptera, Coleoptera, Phasmatodea, Lepidoptera larvae, Spider-head and Shaddock, and the remaining groups were rare. The results showed that: the vegetation types had certain influence on the structure characteristics of soil animal community, and there were differences in individual and community groups of soil animals under different vegetation conditions. Soil animal diversity was positively correlated with evenness index and negatively correlated with its dominance. Soil animal communities in all four habitats reached a moderately similar level. In terms of the vertical distribution of soil fauna, the number of 0 cm ~ 5 cm soil layer is the largest with obvious surface aggregation phenomenon.
