摘　　要：稻田是甲烷(CH_(4))的主要排放源之一,对全球温室气体排放有着重要影响,减少稻田CH_(4)排放是实现“碳达峰”和“碳中和”目标的重要举措。稻田CH_(4)多在淹水的厌氧条件下产生,与水稻根系生长特征密切相关。主要介绍了稻田CH_(4)的排放机理,阐述了水稻根系结构、形态和生理特性与CH_(4)排放的关系以及内在机理,分析了水分管理对稻田CH_(4)排放的影响,提出了目前存在的问题,对未来的研究进行了展望,以期为稻田CH_(4)减排及水稻绿色生产提供理论依据。Paddy field is one of the main sources of methane(CH_(4))emissions and has an important impact on global greenhouse gas emissions.Reducing CH_(4) emissions from paddy fields is an important measure to achieve the goals of"carbon peak"and"carbon neutrality".CH_(4) in paddy fields is mostly produced under flooded anaerobic conditions,which is closely related to the growth characteristics of rice roots.This paper mainly introduced the mechanism of CH_(4) emission in paddy fields,expounded the relationship between rice root structure,morphology and physiological characteristics and CH_(4) emission and its internal mechanism,analyzed the influence of water management on CH_(4) emission in paddy fields,and put forward the existing problems and prospects for future research,in order to provide theoretical basis for CH_(4) emission reduction in paddy fields and green production of rice.
