Therefore, it＇s important to study the discharge of methane from cropland. This paper reviewed the methane emission from agricultural ecosystem, the factors controlling CH4 fluxes from soil, such as water regime, the soil characteristics, and the type and amount of applied fertilizers and so on, the management for mitigation of CH4 emission from cropland, especially from paddy field, and put forward some research suggestions on methane emission in the future. The objective of this paper is to provide reference for controlling methane emission in cropland.展开更多
