摘要
Based on the regionalization of uplands and paddy fields in China, the crop intensity in each region and the available field measurements, N2O emission from cropland in China in 1995 was estimated to be 398 Cg N, in which, 310 Gg N was from uplands, accounting for 78% of the total. 88 Gg N-N2O was emitted from paddy fields with 35 Gg N emitted during the rice growing season and 53 Gg N emitted during upland crop season. N2O emission from upland and from paddy field during upland land crop season accounted for 91% of the total emission.
