根据中国旱田和水田的区划、各地区的作物集约度和田间实测资料，估算出1995年中国农田N2O排放量为398GgN，其中旱地为310GgN，占总排放量的78%。水田共排放N-N2O 88gg，其中水稻生长期排放35ggN，旱作季节排放53ggN。旱地和水田的N2O排放量占总排放量的91%。
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 Gg 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.
