摘　　要：大气CO_(2)浓度升高是全球气候变化的主要驱动力,可直接或间接影响陆地生态系统碳氮循环。阐明稻田生态系统CH_(4)和N_(2)O排放对大气CO_(2)浓度升高的响应及其机制,是农业生产应对全球气候变化的重要组成部分。本文综述了国内外不同大气CO_(2)浓度升高模拟技术平台条件下稻田CH_(4)和N_(2)O排放的响应规律,进一步讨论分析了大气CO_(2)浓度升高影响CH_(4)和N_(2)O排放的相关机制,并展望了今后稻田CH_(4)和N_(2)O排放对大气CO_(2)浓度升高响应的主要研究方向,以期为应对全球气候变化提供理论依据和技术支撑。Elevated atmospheric CO_(2) concentration is the main driving force of global climate change, which directly or indirectly affects carbon(C) and nitrogen(N) biogeochemical cycles of terrestrial ecosystems. It is necessary to clarify the effects and mechanisms of elevated CO_(2) concentration on CH_(4) and N_(2)O emissions from rice fields, for which is an important part of agricultural systems to mitigate global climate change. Therefore, this review focused on the mechanisms of CH_(4) and N_(2)O emissions from rice fields in response to elevated atmospheric CO_(2) concentration under various facilities in different countries, discussed and prospected the effects of elevated atmospheric CO_(2) concentration on CH_(4) and N_(2)O emissions from rice fields. The review would provide an important theoretical basis and technical support for responding to global climate change.
