摘　　要：研究了国内城市生活垃圾清运量、填埋量、构成特点及变化趋势,采用联合国政府间气候变化委员会(IPCC)推荐的用于估算填埋气甲烷产量的IPCC缺省法,对2005～2009年中国城市生活垃圾填埋气甲烷产量进行了初步评估;目前我国年垃圾填埋气甲烷产量已超过50亿m3,可转化为电能200亿kWh左右,人口密度越大、经济越发达地区其填埋气产量越高,在地域上呈现由东到西递减趋势。开发填埋气回收利用工程,不仅能有效地控制温室气体甲烷的排放,而且通过净化后还可获得资源量可观的清洁能源,实现能源与环保的双赢。Based on the survey on quantity,characteristics and changing trend of municipal solid wastes,the methane emission from landfill in China from 2005 to 2009 is calculated by IPCC model in this paper.At present,the annual landfill methane gas production is beyond 5 billion cubic metres,which could produce about 20 TWh electricity powers,if fully used.The research indicated that densely populated and economically developed areas often with higher methane production,showing a decreasing trend from the east to west of China geographically.The potentials of alternative energy are very considerable in some regions.The landfill gas recycling projects can not only effectively reduce the greenhouse gas emissions,improve air quality,but also can yield substantial clean energy resources and economic benefits.And then realize the win-win of environmental protection and energy demand.
