【摘要】：畜禽养殖是农业碳源之一。根据安顺市畜禽数量,估算2001—2015年安顺市畜禽碳排放量。从畜禽碳排放结构、碳排放变异系数、碳排放密度、碳排放经济强度4个方面对其进行分析。研究结果显示:(1)安顺市2001—2006年的畜禽碳排放量连续增长,由86.91万t增长到113.06万t,2007年下降到84.31万t;2007—2010年缓慢增长;2011—2013年相对平稳;2014—2015年又增长。(2)畜禽碳排放主要来自牛和猪,牛年均碳排放量为70.70万t。(3)安顺市2003—2007年各区县畜禽碳排放绝对差异呈现扩大趋势,2008—2014年差异性呈现减小趋势。(4)西秀区的畜禽碳排放密度最高,平坝县最低;镇宁县的畜禽碳排放经济强度最高;紫云县次之;关岭县最低。安顺市政府部门应该研制并推广畜禽养殖温室气体减排技术,降低畜禽养殖碳排放量。
[Abstract]:Livestock and poultry farming is one of the carbon sources in agriculture. According to the quantity of livestock and poultry in Anshun city, the carbon emissions of livestock and poultry from 2001 to 2015 are estimated. The results showed that the carbon emissions of livestock and poultry increased continuously in Anshun city from 2001 to 2006. It increased from 869,100 t to one million one hundred and thirty thousand and six hundred t, and decreased to 843,100 t in 2007. Slow growth in 2007-2010; Relatively stable 2011-2013; In 2014-2015, there was an increase in emissions from livestock and poultry, mainly from cattle and pigs. The average annual carbon emission of cattle is 707,000 t.m3) the absolute difference of carbon emission of livestock and poultry in Anshun city from 2003 to 2007 shows an increasing trend. The difference between 2008 and 2014 showed a decreasing trend. 4) the density of carbon emission of livestock and poultry was the highest in Xixiu area and the lowest in Pingba County. The economic intensity of carbon emission of livestock and poultry was the highest in Zhenning County. Ziyun County followed; Guanling county is the lowest. Anshun city government should develop and promote greenhouse gas emission reduction technology for livestock and poultry breeding to reduce carbon emissions from livestock and poultry breeding.
