Abstract

In contrast to a large body of literature assessing the impact of agriculture greenhouse gas (GHG) emssions on climate change, there is a lack of research examining the impact of climate change on agricultural GHG emissions. This study employed the DNDC v9.5, a state-of-art biogeochemical model, to simulate greenhouse gas emissions in China's rice-growing fields during 1971-2010. The results showed that owing to tempeature rising (on average 0.49-degree C higher in the second 20 years than in the first 20 year) and precipitation ncrease (11 mm more in the second 20 years than in the first 20 years) during the rice growing season, CH4 an N2O emissions in paddy field increased by 0.25 kg C-hm^-2 and 0.25 kg N-hm-2., respectively. The rising temperature accelerated CH4 emission and N2O emission increased with precipitation. These results indicated that climate change exerted impact on the mechanism of GHG emissions in paddy field.
