以广州某生活垃圾填埋场填埋的生活垃圾为研究对象，用普通一级模型估算填埋场从开始运行到2010年底填埋生活垃圾的产甲烷量，比较各模型逐年产甲烷量估算值的相对大小，比较2010年产甲烷量估算值和实测值的大小。结果表明：同一年逐年产甲烷量估算值最大的模型是 SWANA 一级模型，估算值最小的模型是 LandGEM（EPA，2005）；LandGEM（EPA，2005）模型估算值与实测值最接近，是估算该填埋场产甲烷量的最佳模型。“,”Household garbage of one landfill in Guangzhou is used as research object,methane produc-tion of household garbage from the run time to 2010 is estimated with ordinary first order models, the estimated relative methane production values are compared with each year,and the estimated value of 2010 is compared with the measured value.The results show that the model of the biggest estimated methane production value is SWANA first order model,the smallest estimated value is LandGEM(EPA,2005);LandGEM(EPA,2005)is most close to the measured value,and this mod-el is the most appropriate in ordinary first order models used to estimate this landfill.
