基于IPCC方法的新疆畜禽温室气体排放时空分析

Spatial-temporal Analysis of Greenhouse Gas Emission from Livestock Based on IPCC in Xinjiang

在IPCC方法的基础上,对1980-2016年新疆畜禽温室气体排放的时空变化特征进行了研究。结果表明:新疆畜禽温室气体从1980年的1224.01×10^4 tCO2-eq波动升高至2016年的2032.80×10^4 tCO2-eq,增幅为66.08%,年均增长1.41%;畜禽肠道发酵甲烷排放是新疆畜禽温室气体的主要贡献者,占温室气体排放总量的84%,其次是畜禽粪便管理氧化亚氮和甲烷的排放;而主要畜禽温室气体排放以牛和羊为主,其次是马、驴、猪、骆驼和骡;最后通过对2015年新疆畜禽温室气体排放空间变化分析可知,伊犁州直属县(市)温室气体排放量最大,为456.78×10^4 tCO2-eq,而温室气体排放量最小的克拉玛依市仅有4.37×10^4 tCO2-eq,说明新疆畜禽温室气体排放空间差异性较大。

This paper studied the time-space variation characteristics of greenhouse gas emissions of livestock and poultry in Xinjiang from 1980 to 2016.The results showed that the greenhouse gas of livestock and poultry in Xinjiang increased from 1224.01×10^4 tCO2-eq in 1980 to 2032.80×10^4 tCO2-eq in 2016 by fluctuation,with an increase rate of 66.08%and an average annual growth rate of 1.41%;Methane emission from intestinal fermentation of livestock and poultry was the main contributor of greenhouse gas in Xinjiang,accounting for 84%of the total greenhouse gas emission,followed by nitrogen oxide and methane emission from livestock and poultry manure management.The main greenhouse gas emissions of livestock and poultry were cattle and sheep,followed by horses,donkeys,pigs,camels and mules.Finally,through the analysis of the spatial change of greenhouse gas emissions of livestock and poultry in Xinjiang in 2015,it could be seen that the directly affiliated county(city)of Yili prefecture had the largest greenhouse gas emissions,which was 456.78×10^4 tCO2-eq,while the Karamay city with the smallest greenhouse gas emissions only had 4.37×10^4 tCO2-eq,indicating a large spatial difference of the greenhouse gas emissions of livestock and poultry in Xinjiang.
