摘要
氧化亚氮(N2O)是一种高效痕量的温室气体,且大气中N2O浓度正处于持续不断的增长过程中,生活垃圾填埋场是N2O的重要排放源,释放通量远远高出农田、林地、草地等其他生态系统。概述了生活垃圾填埋场覆土N2O的释放以及影响因素,并在此基础上展望了生活垃圾填埋场N2O的排放控制理论和技术的研究方向。
As a high-efficient trace greenhouse gas, nitrous oxide （N20） has a very high warming potential and its concen-tration in atmosphere continues to rise steadily. Landfills of Municipal solid waste （MSW） are main sources of N20 emission reported to be at least 1 to 2 orders of magnitude more than the maximum emissions reported for grasslands, agriculture fields and boreal forests. The factors affecting the N20 emission from the landfill covered soils are summarized. Further re search focuses on controlling N20 emission from the landfill covered soils are propected.
