摘　　要：土壤有机碳具有重要的生态功能,是草原露天矿区生态恢复效果的重要标志。本文从植被恢复、土壤恢复和土壤微生物恢复角度综述当前草原露天矿山生态恢复对土壤有机碳的影响,结果表明植物恢复、土壤恢复、土壤微生物恢复均有可能影响草原露天矿山的土壤有机碳,且土壤微生物同土壤有机碳的变化联系最为密切。同时,探讨了目前研究存在的问题,提出草原露天矿山生态恢复问题的潜在解决策略以及综合研究三者间的相互关系对土壤有机碳的影响具有重要价值,可为相关工作的合理实施以及在此基础上的研究内容深化、范围拓展、技术推广、应用支撑等提供理论参考。Soil organic carbon(SOC),with its critical ecological functions,is a key indicator for assessing the effectiveness of ecological restoration in grassland surface mining areas.This review focused on the effects of ecological restoration on SOC,considering vegetation,soil,and soil microbial restoration.Plant,soil,and soil microorganism all influenced SOC dynamics in grassland surface mine,with soil microorganisms likely playing the most significant role in SOC changes.Additionally,this review identified existing challenges and proposed potential strategies to address issues related to plant,soil,and microbial restoration in these areas.The review also emphasized the importance of investigating the interactive effects between plant,soil,and soil microorganisms on SOC.This review provides theoretical insights to guide the rational implementation of ecological restoration practices and support further research development,technical advancement,and application on this field.
