摘要
基于2000—2020年相关面板数据,运用核密度估计方法、空间相关性分析等测算新疆14个地级行政区畜牧业碳排放量并探究其动态演变情况。结果表明:(1)研究期内新疆畜牧业碳排放整体呈波动上升趋势,且牲畜肠道发酵是其主要源头,核密度曲线表明各地级行政区畜牧业碳排放由集聚向分散演化。(2)研究期内各地级行政区畜牧业碳排放空间相关性加强,且“低-低”集聚类型增多。(3)各地级行政区畜牧业碳排放存在差异,研究期内伊犁畜牧业碳排放量下降最多,减排效果最为突出。
Based on the relevant panel data from 2000 to 2020,the kernel density estimation method and spatial correlation analysis were used to calculate the animal husbandry carbon emissions in 14 prefectural districts of Xinjiang and explore their dynamic evolution.The results showed that:(1)the overall fluctuation of animal husbandry carbon emissions in Xinjiang increased during the study period,and intestinal fermentation was the main source.The kernel density curves showed that the animal husbandry carbon emissions in each district evolved from agglomeration to dispersion.(2)The spatial correlation of animal husbandry carbon emissions in different districts of Xinjiang was constantly strengthened during the study period,and the“low-low”agglomeration types increased.(3)There were differences in carbon emissions from animal husbandry in different districts.During the study period,the carbon emissions of animal husbandry in Yili decreased the most,and the emission reduction effect was the most prominent.
