摘要：

为了更好地了解和掌握秸秆还田对中国农田土壤温室气体排放的影响，笔者根据历年国内相关文献，就秸秆还田对中国农田土壤CO2、N2O和CH4等主要温室气体排放的影响进行较全面的综述。研究表明：秸秆还田能增加农田土壤CO2和CH4的排放通量，对N2O排放通量的影响表现为不确定性，分析了秸秆还田对农田土壤温室气体排放的影响因素，探讨了该领域存在的问题及未来的研究方向。秸秆还田对中国农田土壤温室气体排放有一定影响，对各温室气体影响程度和影响机理不同。

Abstract:

In order to provide better understanding and handling of the influence of straw application on agricultural greenhouse gas emissions in China. The author reviewed the influences of straw application on agricultural greenhouse gas, such as CO2, N2O and CH4 based on literatures in recent year. Research showed that straw application could increase soil CO2 and CH4 emissions fluxes, but the influence on N2O emission fluxes was uncertainty. The author analyzed the influence factors of straw application on agricultural greenhouse gas emissions, the present and future research needs about straw application on the fluxes greenhouse gas from farmland soil were discussed. Straw application influenced agricultural greenhouse gas emissions in China, the influence degree and influence mechanism of each greenhouse gases were different.
