摘　　要：为改善矿区复垦地土壤生态环境,于2018年9月对铜陵市狮子山3个尾矿库复垦地和1个对照样地的土壤动物进行研究。结果表明,共捕获土壤动物24类1191只。优势类群为弹尾目、甲螨、前气门亚目、蚂蚁和鼠妇,占总数的76.99%。样地土壤动物个体数和类群数方差分析表明,香樟林获得土壤动物个体数和类群数显著高于其他样地(P<0.05),刺槐林地与其他样地的个体数无显著性差异,类群数有显著性差异,芒草地和白茅草地个体数和类群数之间无显著性差异(P>0.05)。RDA分析表明,弹尾目与土壤pH、TP显著相关;凋落物层厚度、土壤TN、TC、TOC与双尾目、蚯蚓、双翅目幼虫、鼠妇呈极显著的正相关,与鞘翅目幼虫呈显著负相关。香樟林地对照下的复垦地生态恢复综合评价表现为刺槐林地恢复效果较好,芒草地和白茅草地的恢复效果不显著。In order to improve the soil ecological environment of the reclaimed land in the mining area,soil animals in 3 tailings reservoir reclaimed land and a control plot in Shizishan,Tongling City were studied in September 2018.The results showed that a total of 1191 soil animals of 24 types were captured.The dominant taxa were placoderm,acaroid mite,anterior valve suborder,ant and murine,accounting for 76.99%of the total.Sample area soil animal number of individuals and groups of variance analysis showed that the camphor forest soil animal individual number and group number was significantly higher than the other sample(P<0.05),there was no significant difference in the number of individuals between acacia woodland and other plots,there was a significant difference in the number of groups,and there was no significant difference between the number of individuals and groups in the grasslands of miscanthus and cogon grass(P>0.05).RDA analysis showed that elastomer was significantly correlated with soil pH and TP.Litters layer thickness,soil TN,TC and TOC were significantly positively correlated with dicetops,earthworms,diptera larvae and rat females,but significantly negatively correlated with coleoptera larvae.The comprehensive evaluation of ecological restoration of reclaimed land under the control of Xiangzhang woodland showed that the recovery effect of robinia pseudoacacia forest was good,but that of Mang grassland and Baimao grassland was not significant.
