摘要/Abstract

摘要： 通过调研多年来国内外农田N2O排放的研究结果,建立了农田N₂O年度排放数据库,并分析了N₂O排放与各环境因子之间的关系.相关分析表明, N₂O排放与温度及降水呈显著正相关,与土壤pH值、有机碳及氮含量无显著相关.依据政府间气候变化专门委员会对农田N₂O排放系数的定义和确定方法,用年平均气温及降水量对其进行修正.结果表明，经平均气温修正后的排放系数并不减小农田N₂O排放的估计误差,但用年降水量进行修正后能减小平均相对误差16%左右.

Abstract: Based on the direct measurements of annual N₂O emission from 207 field experiments reported in literatures between 1982 and 2003,this paper established a database of annual N₂O emission from agricultural fields.Correlation analysis indicated that the N₂O emission from agricultural soils was significantly correlated with climatic factors temperature and precipitation,while no significant correlations were observed between N₂O emission and edaphic parameters pH,organic carbon and nitrogen.According to the definition of N₂O emission factor and its quantification by the Intergovernmental Panel on Climate Change,the N₂O emission factor was modified by annual mean temperature and annual precipitation,respectively. The results suggested that the modification with precipitation might significantly reduce the estimated error of N₂O emission by about 16%,while that with temperature did not reduce the error,in comparison with the default emission factor by the Intergovernmental Panel on Climate Change.
