甲烷是一种重要的温室气体,而稻田是甲烷的重要排放源之一。因此,对稻田甲烷排放进行研究具有重要的意义。阐述了稻田甲烷产生、氧化及传输的机理,归纳了稻田甲烷排放的日变化、季节变化、年际变化等规律,重点分析了稻田甲烷排放的影响因子,包括温度、水分、土壤有机质、土壤氧化还原电位、土壤pH、施肥等。

Methane is an important greenhouse gas, but the rice field is one of the important sources of the methane. Therefore, it is important to study the discharge of the methane in the rice field. The mechanisms of methane produce, oxidation and transfer were elaborated in the paper firstly, and then laws of were summed up in day variation, seasonal variation, and interannual variation of the rice field methane emission. Influencing factors of the rice field methane emission were analyzed selectively, such as temperature, moisture content, organic quality of soil, Eh, soil pH , apply fertilizer, and so on.
