摘　　要：CH4是大气中仅次于CO2的最重要的温室气体之一,其温室效应贡献已达15～20%。中国稻田是CH4的重要排放源,对全球大气的CH4排放起着重要的作用。本文较为详细地介绍了近几十年来国内外关于稻田CH4排放的研究进展。对稻田CH4的排放机理、CH4的排放规律及影响稻田CH4排放的各种因素作了详细分析,并相应地提出了控制稻田CH4排放的各种措施,最后提出了今后我国稻田CH4排放研究应加强的几个方面内容。Methane(CH_4)is the second most ubiquitous greenhouse trace gas after CO_2; however, CH_4 more effectively absorbs infrared radiation than CO_2 and is one of the most rapidly increasing greenhouse gases in the atmosphere, which accounts for about 15 to 20 percent of the enhanced warming. Chinese paddy fields are the important resources in methane emission, which play a vital role in methane increasing in atmosphere. In this paper, recent advances in the research on methane emission from paddy fields were reviewed. We analysed the mechanism and the various regularity of methane emission and the various factors affecting methane emission,and control measures of methane emission are also discussed in detail. The research emphasis in future is briefly suggested in the end.
