摘要：

综述了水分管理对稻田甲烷产生、氧化和传输排放的影响以及秸秆还田对稻田甲烷排放和固碳的影响，并提出了今后中国稻田CH4排放应加强以下2方面的研究：（1）水分管理对稻田甲烷产生机理的研究；（2）秸秆还田对稻田甲烷排放和土壤固碳的综合影响研究，旨在为以后的水稻生产如何进行水分管理和秸秆还田提供参考和依据，以期充分发挥稻田的生态效益。

Abstract:

This paper reviewed production, oxidation and transmission of methane in rice paddy fields as affected by the water management, the influence of rice straw incorporation on emission of methane and carbon sequestration in rice paddy fields. Two aspects were put forward which should be strengthened about methane emission from Chinese rice paddy fields in the future: (1) Research on production mechanisms of methane in rice paddy fields; (2) Research on the comprehensive influence of rice straw incorporation on emission of methane and carbon sequestration in rice paddy fields. Some suggestions were as references for us on how to carry out water management and how to incorporate rice straw in rice paddy fields, in order to develop the ecological efficiency of rice paddy fields.
