[Objective] To study the influence of earthworm activities on soil nutrients in copper mine tailings in order to provide references for the ecological restoration by soil animals in copper tailings.[Methods] 8 treatments were designed and lasted for one month in laboratory(20℃).[Results] (1) The inoculation of earthworm affected the soil nutrients as following order:phosphorus >organic matter >K >available nitrogen. Soil nutrients content increased with the increase of earthworm density;(2) The inoculation of earthworm with the coverage of straw on copper tailings affected the soil nutrients as phosphorus >available nitrogen >K >organic matter, and soil nutrients content increased with the increase of the earthworm density;(3) Earthworm inoculation with coverage of straw showed higher impact on soil nutrients than earthworm inoculation only, and the affecting speed were as phosphorus >K >available nitrogen >organic matter.[Conclusion] Earthworms do have effect on soil nutrient restoration in copper mine tailings, the greater the earthworm density, the higher the impact.
