Abstract
China has the world's largest area of rice paddy. As such, emissions of methane (CH4) from China are of interest in understanding the global CH4 budget. Using a simplified process-based methane emission model and a georeferenced database, CH4 emission rates from 329 defined agricultural zones in China, where rice production occurred, were estimated in this study. The calculated daily CH4 emission rates ranged from 0.12 g m−2 to 0.70 g m−2 with an average value of 0.44 g m−2. The annual CH4 emissions varied between 25 g m−2 and 80 g m−2. On average across the whole rice growing area in China, 59.9 g m−2 CH4 was released annually. Total CH4 emission was 16.2 Tg year−1 (1 Tg = 1012 g). Although the model and supporting database used had some uncertainties, these results demonstrated the ability to assess CH4 emissions at the regional level within the framework of climate-plant-soil interactions.
