摘要
文章以2020年重庆市畜禽养殖量为依据,以肠道发酵甲烷(CH_(4))排放、粪便管理CH_(4)排放和氧化亚氮(N_(2)O)排放作为核算对象,对重庆市畜禽养殖温室气体排放进行了初步核算。研究发现全市畜禽养殖温室气体排放在类型上主要以畜禽肠道发酵CH_(4)为主,在畜种上主要以牛为主。
Based on the livestock and poultry production volume in Chongqing in 2020,CH_(4) emissions from intestinal fermentation,CH_(4) emissions from feces management and N_(2)O emissions were taken as the accounting objects to calculate the greenhouse gas emissions from livestock and poultry production in Chongqing.It was found that CH_(4) was the main type of greenhouse gas emissions from livestock and poultry farming in the whole city,and the main type of greenhouse gas emissions from livestock and poultry farming was cattle.
