An analytical model for methane and oxygen transport through a single soil cover considering diffusion, advection, and oxidation was developed. The results obtained by the analytical model agree well with those obtained by the numerical model and the column tests. Dimensionless analysis indicates that methane emission flux is more sensitive to the variation of Pe and Da numbers when advection dominates methane transport (Pe ≥ 1) and oxidation dominants methane transport (Da ≥ 10), respectively. It also indicates that landfill gas pressure build-up will decrease the amount of oxygen migrating into the soil. The methane emission flux for the case with Sr = 0.2 is 5.30 and 200 times greater than the cases with Sr = 0.5 and 0.8, respectively. The methane removal efficiency for the case with Sr = 0.8 is 1.25 and 1.58 times greater than the cases with Sr = 0.5 and 0.2, respectively. With the increase of Sr (soil moisture content), methane oxidation rate increases, and diffusion coefficients and advection rates decrease. The methane removal efficiency was increased because more amount of methane was stuck and oxidized in the soil.

建立了考虑到扩散，对流和氧化作用的甲烷和氧气在单一土壤覆盖层中迁移的分析模型。通过分析模型获得的结果与通过数值模型和柱测试获得的结果非常吻合。量纲分析表明，甲烷排放通量是变化更敏感Pe的和大数字时平流支配甲烷传输（Pe的 ≥1）和氧化优势种甲烷传输（沓 分别≥10），。这也表明，垃圾填埋气压力的增加将减少迁移到土壤中的氧气量。Sr  = 0.2的情况下的甲烷排放通量为5.30，是Sr = 0.2的情况下的200倍。Sr 分别为0.5和0.8。Sr  = 0.8的情况下的甲烷去除效率分别是Sr  = 0.5和0.2的情况下的1.25和1.58倍。随着Sr（土壤水分含量）的增加，甲烷的氧化速率增加，扩散系数和对流速率降低。由于更多的甲烷卡在土壤中并被氧化，因此提高了甲烷的去除效率。
