摘　　要：对平朔安太堡露天煤矿恢复生态系统中不同恢复阶段的大型土壤动物群落组成进行了调查,共获取大型土壤动物316头,隶属4纲8目30科。利用DIC多样性指数与密度-类群多样性指数(DG指数)以及Gower相似性指数对土壤动物群落结构进行了分析。结果表明:随着土地复垦与生态重建时间的延长,恢复生态系统中土壤动物群落的结构趋于复杂;在排土场形成到复垦13年的这个恢复阶段中,大型土壤动物群落的演替处于增长期,且在增长期内,土壤动物群落的增长速度为快-慢-快;在恢复时间较长的生态系统之间,土壤动物群落之间相似性指数值相对较大。An investigation was made on the compositions of soil macro-fauna in Antaibao Opencast Coalmine ecosystems at three restoration stages in Pingshuo of Shanxi Province. A total of 316 individuals belonging to 30 families, 8 orders and 4 classes of soil macro-fauna were collected, and the community structure was analyzed by using DIG index, DG index, and Gower similarity index. The results indicated that the community structure of soil macro-fauna in restored ecosystems tended to be complex with the time of land reclamation and ecological reconstruction. At the restoration stage from the 1st to the 13th year after reclamation, the biomass of soil macrofauna increased, with a speed of fast-slow-fast. Higher values of Gower index were observed among the ecosystems with longer term restoration, indicating that soil macro-fauna had a relatively higher similarity in the ecosystems with longer term restoration than in those with shorter term restoration.
