为了研究水磨沟公园土壤动物群落结构,于2006年4月15日至9月21日在水磨沟公园不同高度选择3个取样区,每个取样区设立两个不同的取样点,采集了0～5、5～10、10～15cm3个不同层次的大中型土壤动物.共获得土壤动物1153个,分别属于3门8纲18目,其中鞘翅目、中腹足目、小引类为优势类群,占全捕量的61%.蜘蛛目、伪蝎目、半翅目为稀有类群,仅占总捕获量的2.34%,其余为常见类群.分析表明,在不同高度土壤动物群落物种组成和多样性之间有明显的区别;山顶土壤动物个体数量和群落物种多样性指数明显的高于山地土壤动物个体数量和群落物种多样性指数.同时随着土壤深度的增加土壤动物物种数量逐步减少,表现出明显的垂直分布特征.
In order to study the community structure of soil animal in Shuimogou Park, three sampling zones were selected at different heights from Shuimogou Park from April 15 to September 21, 2006. Two sampling points were set up for each sampling zone and 0 ~ 5,5 ~ 10,10 ~ 15cm3 soil mesothelioids, 1153 soil animals were found, belonging to 3 classes, 8 classes and 18 orders, respectively. Among them, Coleoptera, 61% of the total catch.Arachnids, Pseudoscimenea and Hemiptera were rare species, accounting for only 2.34% of the total catch, the rest were common species.Analysis showed that species composition and diversity of soil animal community at different heights The number of soil animal and the index of community diversity were significantly higher than those of the mountainous soil animals and the species diversity index of the community.At the same time, the number of soil animal species decreased gradually with the increase of soil depth, showing obvious The vertical distribution features.
