摘要
为了解枣园土壤动物群落多样性及其结构特征,选取陕西榆林地区清涧县和佳县枣园作为研究样地进行土壤动物调查,共捕获土壤动物314只,分别隶属于软体动物门、环节动物门、节肢动物门3门4纲12目。结果表明:弹尾目和鞘翅目成虫为优势类群,占全捕量的57.54%,是该区土壤动物的主体;膜翅目蚁类、鞘翅目幼虫、蜘蛛类、螨类、腹足类等为常见类群。上述结果显示土壤动物群落的多样性在不同土层中基本上是随土层深度的增加而递减,并且表聚性明显。
In order to understand the diversity and the structure of soil animal community in jujube gander,taking that in Qingjian County and Jiaxian County as the research type places,the soil animal investigations were carried on.314 soil animals were caught,which subordinated separately in the mollusk gate,the annulate gate and 3 phyla 4 class 12 order.The results showed that the ball tail phyla and the hymenoptera prospect,tubing up 57.54% of the total phyla,were the dominant class groups and main part of soil animals in this area.The results also showed that the hymenoptera ant class,the coleoptera larva,the arachnids,man kind of,the gastropoda was the common class group,the hymenoptera were the common class groups.These results indicated that the community multiple of soil animals degreased progressively basically among different soil strata sing soil depth and showes an obvious aggregation.
