The results show that:①The forest soils have the stronger nitrification, but also the nitrification in surface horizon is stronger than the undersoil's.
结果表明：①森林土壤有较强的硝化活性，且表土层比底层土强，同时根际土利于硝化作用进行，根际效应R/S在4.5左右；②淹水厌气培养24h，-N的消失率为52%～58%，占第10天的55%～71%，且表土层-N的消失率比底层土大；③参与同化反硝化作用的还原酶活性较强，在培养24h后，被还原的基质数量占加入基质数量的70%～90%。

The large-scale soil animal sorts were gathered by hand, while the medium and the small soil animals were separated by the funnel law and the funnel law, totally 314 soil animals were caught, which subordinated separately in the mollusk gate ,the annulate gate and 3 phyla 4 class 12 order results showed that the ball tail phyla and the hymenoptera prospect, tubing up 57.54% of the total phyla ,are the dominant class groups and main part of soil animals in this area; The hymenoptera ant class, the coleoptera larva, the arachnids, man kind of, the gastropoda is the common class group the hymenoptera are the common class groups .these result indicate that the community multiple of soil animal's degreases progressively basically among different soil strata sing soil depth and has an obvious aggregation .
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。关键词：枣园；土壤动物；群落多样性；陕西榆林
