稻田温室气体（CH4和N2O）排放影响因素及其减排措施研究进展

甲烷(CH4)和氧化亚氮(N2O)是重要的两种温室气体,近一个世纪以来,大气中这两种气体浓度持续升高,进而引起温室效应明显加剧和气候变暖等极端气候的频繁出现.稻田生态系统是大气CH4和N2O的重要源.稻田温室气体的排放受土壤性质、气候条件及人为活动等因素的交互作用和综合调控,CH4和N2O排放量与各因素的变异程度、敏感程度密切相关.全面综述了影响稻田温室气体排放的因子及温室气体减排措施的研究进展,可为制定我国稻田温室气体减排措施、促进农业可持续发展以及生态环境协调发展提供参考.

Research progress of emission influence factors and reduction measures of greenhouse gases in paddy field

Methane (CH4) nitrous oxide (N2O) are important greenhouse gases. The concentration of the twogases in atmosphere is increasing continuously in almost a century, thereby resulting in significant increase ofgreenhouse effect and frequent appearance of extreme climate, such as climate warming. Paddy field ecosystem is animportant source of atmospheric CH4 and N2O. The emissions of greenhouse gases are affected by the interaction andcomprehensive control of soil properties, climatic conditions and human activities factors and so on. The papercomprehensively reviewed the research progress of emission factors and reduction measures of greenhouse gases, toprovide great significance to develop emission reduction measures of greenhouse gases for paddy field in China, andto promote the sustainable development of agriculture and coordinated development of ecological environment.
