摘　　要：土壤有机碳是土壤肥力的重要标志,土壤有机碳处在不断的动态循环之中,农田土壤有机碳储量的下降已经引起重视.农田土壤有机碳以二氧化碳和甲烷的形式释放出,农田土壤成为全球碳循环的主要碳源.中国是农业大国,研究二氧化碳和甲烷的产生机理、影响因素和减排措施对于保持土壤肥力、控制温室气体排放、维护生态平衡都具有重要的现实意义.本文就二氧化碳、甲烷的产生机理、影响因素和减排措施等研究的进展作一综述.SOC is important symbol of soil fertility, SOC is in perpetual dynamic circulation, the decline of SOC content in agricultural soil has arose people＇ s recognition. SOC in agricultural soil release in form of CO2 and CH4, agricultural soil become primary C source in global C circulation. China is a agricultural country, it have important pratical meaning to research CO2 and CH4 s produce mechanism factors and reduce measures for keeping soil fertility controling release of greenhouse gas and maintenance of ecological balance. This paper make a summary about CO2 and CHas produce mechanism factors and reduce measures.
