摘　　要：为探究非正规垃圾填埋场填埋气甲烷含量的影响因素及其作用机制,试验选取4个非正规垃圾填埋场,对其垃圾组分和填埋气组分进行长期跟踪与采样分析。结果表明,采取封场措施有助于显著增加填埋气的甲烷含量。填埋气的甲烷含量与月均气温呈正相关。随着气温的上升,相比甲烷最低含量和甲烷平均含量,各堆点甲烷最高含量增加幅度均最大。研究表明,采取封场措施和建设覆盖层是管理运营非正规垃圾填埋场的优先选择。In order to explore the influencing factors and mechanisms of methane content in landfill gas from informal landfills,four informal landfills are selected for long-term tracking and sampling analysis of their garbage and landfill gas components in this experiment.The results indicate that implementing site closure measures can significantly increase the methane content of landfill gas.The methane content of landfill gas is positively correlated with the monthly average temperature,as the temperature rises,compared to the lowest and average methane content,the highest methane content at each stacking point increases the most.Research has shown that implementing closure measures and constructing cover layers are the priority choices for managing and operating informal landfills.
