摘要:  氧化亚氮(N2O)是一种重要的温室气体, 农田土壤是其排放的重要源。本研究通过本地参数修正的IPCC2006计算方法, 结合统计资料计算中国农田土壤的N2O直接排放量。结果表明: 从1980年到2007年中国农田N2O排放年均增长7.6%, 2007年N2O-N排放量达到288.4 Gg。2007年化学氮肥投入、有机物质投入、作物秸秆投入、有机土排放对农田N2O直接排放的贡献份额分别为77.64%、15.57%、6.46%和0.33%。从分布格局看, 2007年农田N2O直接排放总量较大省份主要集中在华北地区和四川盆地, 单位耕地面积N2O排放量较高的地区主要集中在华北地区和东南沿海。

Abstract:  Nitrous oxide is an important greenhouse gas and agricultural soil is a major source of nitrous oxide emission. The aim of this study was to estimate direct nitrous oxide emissions from agricultural soils of China through the IPCC2006 guideline method updated with combined local parameters and statistical data. The results show that average annual growth rate of direct nitrous oxide emission from agricultural soils of China is 7.6% for 1980~2007, releasing 288 400 tons N in 2007. The contributions of chemical nitrogen fertilizer input, organic material input, crop residues input and histosol soils to direct nitrous oxide emission from agricultural soils of China are 77.64%, 15.57%, 6.46% and 0.33% respectively in 2007. From the distribution pattern, provinces of high nitrous oxide emission are mainly concentrated in North China Plain and Sichuan Basin. On the other hand, provinces of high nitrous oxide emission per unit arable land area are mainly in North China Plain and the Southeast coast area.
