江苏省畜禽养殖温室气体排放估算

根据畜禽养殖的活动数据和温室气体排放因子,采用IPCC指南(2006)推荐的排放系数法,估算江苏省2000~2009年畜禽温室气体排放量。结果显示:江苏省畜禽养殖甲烷年平均排放总量为174.63 Gg,氧化亚氮年平均排放总量为20.80 Gg。其中,畜禽肠道发酵是重要甲烷排放源,年平均排放量为106.63 Gg,占畜禽甲烷排放总量的61.06%;粪便管理甲烷排放是畜禽温室气体的另一重要来源,年平均排放量为68 Gg,占甲烷排放总量的38.94%;2000~2009年期间江苏省畜禽温室气体排放量总体呈下降的趋势,肠道发酵羊的甲烷排放量最大,粪便管理中温室气体排放生猪排放贡献最大,前者主要是由排放...

Summary:根据畜禽养殖的活动数据和温室气体排放因子,采用IPCC指南(2006)推荐的排放系数法,估算江苏省2000~2009年畜禽温室气体排放量。结果显示:江苏省畜禽养殖甲烷年平均排放总量为174.63 Gg,氧化亚氮年平均排放总量为20.80 Gg。其中,畜禽肠道发酵是重要甲烷排放源,年平均排放量为106.63 Gg,占畜禽甲烷排放总量的61.06%;粪便管理甲烷排放是畜禽温室气体的另一重要来源,年平均排放量为68 Gg,占甲烷排放总量的38.94%;2000~2009年期间江苏省畜禽温室气体排放量总体呈下降的趋势,肠道发酵羊的甲烷排放量最大,粪便管理中温室气体排放生猪排放贡献最大,前者主要是由排放系数决定,后者取决于饲养量。

Livestock and poultry; Greenhouse gas; Emission coefficient; Methane; Nitrous oxide
According to the activity data of livestock and poultry as well as greenhouse gas emission factors,by using the emission coefficient method recommended by the IPCC Guidelines(2006),this study estimated the greenhouse gas emission from the livestock and poultry in Jiangsu province from 2000 to 2009.The results indicated that the annual average methane emission from the livestock and poultry in Jiangsu province was 174.63 Gg,and the annual average emission of nitrous oxide was 20.80 Gg.Among them,the enteric fermentation of livestock and poultry was an important source of methane emission,and the annual average methane emission from the enteric fermentation reached 106.63 Gg,accounting for 61.06% of the tot
