湿地具有极其特殊的生态功能,是地球上最重要的生命支持系统,也是CH4的重要排放源。CH4作为备受关注的温室气体之一,许多国内外学者都对湿地CH4产生、氧化和排放进行了深入研究,并取得了大量研究成果。本文综述了国内外湿地CH4产生、氧化和排放的研究现状,总结了湿地CH4排放的影响因素以及CH4排放的模型估计,并对今后湿地CH4研究提出了展望。
Wetlands are provided with special ecological functions and the most important life-support systems.Wetlands are major natural sources of atmospheric CH4.CH4 is one of greenhouse gases which attracting much attention.Many domestic and foreign scholars have studied on CH4 production,oxidation and emission deeply and achieved a great deal of research results in wetlands.In this paper,researches of both at home and abroad on CH4 production,oxidation and emission from wetlands are summarized;CH4 emission factors and CH4 emission estimate models from wetlands are summed up;also,prospect on the future of CH4 research from wetlands is presented.
