| 摘 要： | 中国是世界上最大的水稻生产国, 水稻种植面积占全球总种植面积的30%。水稻生产在粮食安全方面起着重要的作用, 稻田却是温室气体甲烷(CH4)和氧化亚氮(N2O)的重要排放源。文章综述了稻田CH4和N2O的产生过程、影响因素及时空变异规律, 总结了近年来我国稻田CH4和N2O排放总量的估算结果, 并提出了针对性的温室气体减排措施。

| Abstract: | China is the largest rice-producing country in the world, with the area of rice field accounting for about 30% of world total. While crucial for food security, rice production is a large source of greenhouse gases, known as methane(CH4)and nitrous oxide(N2O). This paper reviews the processes of CH4 and N2O emission from rice paddies, their influencing factors, and the temporal and spatial variations of these greenhouse gases. It also summarizes the various estimates of CH4 and N2O emission from China''s paddy fiels,, and proposes mitigation options. |
