: 垃圾填埋场是全球重要的 CH4排放源。基于中国 1955 个垃圾填埋场基础数据和排放因子数据库,核算了中国 2012 年垃圾填埋场 CH4排放水平,同时分区域和分规模推荐了基于已填容量的计算模型。2012 年中国垃圾填埋场的 CH4排放量为 148. 12 万 t,广东排放量最高,西藏排放量最低。华东地区的垃圾填埋场 CH4排放在 7 个区域中占全国排放比例最高,达到 33. 00%,西北地区排放占比最低,为 8. 76%; 大型填埋场( I 类) CH4排放占总排放比例达 45. 88%。中国垃圾填埋场 CH4排放在空间分布上具有较强的集聚性,北京 - 天津,上海 - 绍兴 - 宁波,广州 - 东莞 - 深圳 - 清远构成了中国垃圾填埋场 CH4排放的三大核心区域。垃圾填埋场单位已填容量的 CH4排放水平在 0. 86 ~1. 83 kg/m3。

Abstract: Landfill is one of the key CH4 emission sources in the world.The CH4 emissions of 1,955 landfills were calculated,based on the detailed facility data and emission factor database. According to different scale and different location of landfills,an estimation model of CH4 emissions from landfill was proposed,based on amount of landfill waste.The CH4 emissions reached 1.48 million tons in China in 2012,in which the biggest contribution was Guangdong,while the smallest was Xizang.The emissions of East China was the largest one in all seven regions,accounting for 33. 00% of total emissions,and the emissions of Northwest China was the least,with emission share of 8.76%.The emissions from large scale landfills ( I type) occupied 45. 88% of the total emissions. The results showed that the distribution of CH4 emission was spatially clustered,with Beijing-Tianjin,Shanghai-Shaoxing-Ningbo, Guangdong-Dongguan-Shenzhen-Qingyuan as the three hotspots.The CH4 emissions per cubic meter of landfill waste ranged between 0. 86 ~ 1. 83 kg.
