摘　　要：对北京西卓家营退化湿地恢复1年后其中的土壤节肢动物群落结构进行了研究,并与未恢复的荒滩和周围的杏树林中土壤节肢动物群落进行了比较。通过手拣法、Tullgren法对获得的土壤动物进行分离、分类,共获得39类3 226只,隶属4纲19目36科。调查结果显示恢复湿地内土壤节肢动物的个体数、类群数、多样性与荒滩相比均显著增加(p<0.05),而与周边的杏树林没有明显差异(p>0.05)。恢复湿地中紫穗槐、灌木柳、蒙桑、沙棘等4种植物种植区的土壤节肢动物群落结构差异不显著(p>0.05),不同土层间的差异也不显著(p>0.05)。这说明湿地恢复取得了一定的效果,但由于恢复时间较短,仍然处于湿地恢复的初期阶段。By the methods of hand-sorting,Tullgren＇s,the soil arthropod composition structure in the wetland restored for a year in Westzhuojiaying of Beijing was investigated,also compared with the wasteland and surrounding apricot forest.A total of 3 226 soil animals in 39 groups belonging to 4 classes,19 orders,36 families were collected.Compared with the wasteland,the number of individuals and groups,and the diversity of the soil arthropods in restored wetland were significantly（p0.05） increased,while with the surrounding apricot forest not significantly different.The community structure of soil arthropod had no significant difference（p0.05） among the areas of Amorpha fruticosa,Salix saposhnikovii,Morus mongolica,and Hippophae rhamnoides,also no significant difference（p0.05） among the different soil layers.The results showed that wetland restoration truly achieved some effects,but it was still in the early stages of recovery due to short restoration time.
