摘要: 对东北羊草草原土壤动物特征的研究表明i,土壤动物共有4门6纲14目。其水平分布规律是杂类草群落>羊草群落>拂子茅群落>榆树疏林>碱茅群落>碱蓬群落。土壤动物的数量和生物量的季节变化趋势相似,最大值均出现在8月份。随着土层的加深其数量逐渐减少,0-10cm上层中土壤动物数量约占总数的50%以上。

Abstract: Studies on the characteristics of soil fauna in Aneurolepidium chinense grassland show that it can be classified into 14 orders belonging to 4 phyla and 6 classes.Its horizontal distribution pattern is in the order of weeds community>Aneurolepidium chinense conmmunity >Calamagrostis epigeios community>Ulmus pumila sparse woods>Puccinellia tenuiflora community>Suaeda glauca community.The seasonal variation of its amount and biomass is similar and both of them have a peak value in August.Its amount is decreased with increasing soil depth, and occupies 50% of the total in 0-10cm soil later.

Key words: Soil fauna, Aneurolepidium chinense grassland, Distribution of soil fauna
