温室气体CH4是导致气候变化、引起全球变暖的因素之一。垃圾填埋场是CH4重要的人为释放源，而填埋场覆盖土CH4氧化能有效削减CH4排放。本文对近年来国内外在影响覆盖土CH4氧化的主要因素方面取得的研究成果进行了总结，提出影响覆盖土CH4氧化的主要因素有：土壤含水率、土壤pH、土壤温度、土壤碳氮含量、土壤粒径、气象条件、CH4及O2浓度、重金属及覆盖土材料。最后，对其后的研究方向进行了展望，指出通过优选覆盖土材料以及控制环境状态，可以有效提高覆盖土CH4氧化速率，减小垃圾填埋场CH4释放。

CH4, as a serious greenhouse gas, is one of the reasons for climate change and global warming. Municipal solid waste (MSW) landfill is a significant source of anthropogenic CH4, but the use of landfill cover soil (LCS) is seen as a key technology for the mitigation of CH4 emissions from landfill. In this paper, research progress about the main factors affecting CH4 oxidation in LCS were reviewed, and the major factors influencing CH4 oxidation potential in LCS included soil water content, soil pH, soil temperature, soil carbon and nitrogen content, soil particle, weather condition, CH4 and O2 concentrations, metal content and landfill final cover material. Finally, the future research directions of MOP in LCS were discussed, and through optimizing cover material and controlling environment condition, MOP can be effectively improved and mitigation of CH4 emissions from MSW landfills can be decreased.
