对封闭式垃圾填埋场的填埋气体和植被特征进行了调查。结果表明，填埋场的稳定化过程是影响填埋气体组分的重要因素。随着填埋场封场时间的延长，植被的覆盖度、高度和种类逐渐增加。在调查的细胞中观察到14种，主要是芦苇，一种入侵的多年生植物。有植被覆盖土壤的甲烷和二氧化碳浓度低于无植被覆盖土壤。
An investigation was carried out to elucidate landfill gas (LFG) and the vegetation characteristics in closed landfill. The results indicate that the stabilization process of the landfill is an important factor influencing the components of landfill gases. The coverage, height and species of vegetation increase with the closed time of landfill. Fourteen species were observed in the investigated cells, dominated by Phragmites australis, an invasive perennial plant. The concentrations of methane and carbon dioxide from vegetated cover soil were lower than those from non-vegetated cover soil.
