摘　　要：畜牧业已经成为全球温室气体的主要排放源。通过开展重庆市畜牧业温室气体排放量估算及评价,结果表明,重庆市畜牧业温室气体的排放量受畜牧养殖量影响;牛是重庆市畜牧业温室气体排放中的关键排放源,对温室气体的排放贡献最大,其次是猪;农户散养反刍动物肠道发酵甲烷排放量比规模化饲养的排放量高。通过提高畜牧业养殖规模化率、减少反刍动物肠道发酵甲烷排放、合理利用畜禽粪便以及植树造林增加碳汇吸收等方法可有效减少畜牧业温室气体排放。Agriculture has become the main source of greenhouse gas emissions.Evaluation on greenhouse gas emission of livestock in Chongqing was carried out,the results showed that,the greenhouse gas emissions of livestock were basically proportional to breeding quantity;and cattle were the key sources and had main contribution to greenhouse gas emission of livestock in Chongqing;and the pigs were the second for greenhouse gas emission and greenhouse gas emission from the loosing raise of farmers was higher than that from scale feeding.By raising livestock breeding scale,reducing the rate of ruminant animal gut fermentation methane emission,rationally utilizing animal manure and increasing carbon absorption by planting trees,the greenhouse gas emission of livestock could be effectively reduced.
