中文摘要：
稻田甲烷产生、氧化等过程不仅影响甲烷排放量，还影响其稳定性碳同位素组成；反之，稻田所排放甲烷的稳定性碳同位素组成也可用来定量研究甲烷的产生和氧化过程。20世纪80年代以来，国外已将稳定性碳同位素方法广泛应用在稻田甲烷的研究中。本文介绍了稳定性碳同位素方法的基本原理及其在稻田甲烷产生、氧化过程研究中的应用，指出了该方法在稻田甲烷研究中的不确定因素，为我国稻田甲烷的深人研究提供了新的有力手段。
英文摘要：
Methane production and oxidation in paddy fields not only affects methane emission from the fields, but also influences isotopic carbon composition of the methane emitted into the atmosphere ; hut in turn, by determining isotopic carbon composition of emitted methane, quantitative study of the processes of methane production and oxidation is made feasible. Since the 1980s, the stable carbon isotope technique has been widely applied in the research on methane in pad- dy abroad. By introducing the fundamental principles of the stable carbon isotope technique and their application in the research on methane production and oxidation in paddy fields, and discussing some uncertain factors of its application in the study, the paper provides the study of methane emission from paddy fields in China with a new strong means.
