Abstract: It is of great significance to study the carbon emission of livestock breeding in Xinjiang,China, which enriches the theoretical and empirical research content related to agricultural carbon emissions,and innovative practice of greenhouse gas carbon emissions from livestock farming,and also promotes the sustainable development of animal husbandry in Xinjiang. Carbon emission coefficient and equity evaluation model were used to calculate the carbon emissions of livestock breeding in Xinjiang during 1995-2015,and to analyze the fairness of carbon emission in livestock breeding in 14 prefectures from two aspects of production efficiency and economic efficiency. The results show that the total amount of carbon emissions from animal husbandry in Xinjiang has gone through three stages of development “ rising- falling-rising”,and the overall trend is on the rise,which increases from 324.90×10⁴ t to 524.31×10⁴ t. The per capita carbon emissions fluctuate slightly from 0.27 t to 0.22 t, the carbon emissions of per ten thousand yuan GDP decreases significantly from 3.95 to 0.73. The carbon emission is larger in the areas where the minority concentrates and the water and pasture are rich,while smaller in the areas where the secondary and tertiary industry are flourishing,but the water and pasture are short,Kashi has the highest amount of carbon emission while Karamay has the least in 2015. The equity of Carbon emissions of the animal husbandry is lower in Xinjiang,the Gini coefficient of production efficiency is 0.42,which is in the unfair state of“big gap”,the Gini coefficient of economic efficiency is 0.48,and it is also in the unfair state of“big gap”,the fairness between“production level carbon emission”and“economic level carbon emission”has exceeded the“0.4”distribution gap warning line. The production efficiency and economic efficiency of Urumqi,Karamay, Turpan,Hami and Changji are all greater than 1,which belongs to the“high-high”type,The production efficiency in Akesu and Kashi areas is greater than 1 but the economic efficiency is less than 1,which belongs to the “high-low”type,the production efficiency in Bazhou and Tacheng areas is less than 1,and the economic efficiency is greater than 1,which belongs to the“low-high”type. The production efficiency and economic efficiency of direct under Ili Prefecture and Altay,Bortala,Kizilsu,Hotan,Hetian area are less than 1,which belongs to the “low-low”type. The economic efficiency and production efficiency of 50% states are less than 1,because the resources have not been effectively configured,and the carbon emissions of animal husbandry affected the environmental equity. As Xinjiang is now in a critical period of agriculture and animal husbandry modernization,it will be necessary to reduce the carbon emission and boost the coordinated development of animal husbandry. In this paper,some suggestions are given as follows: firstly,the government should show concern for and give support to the low carbon development of animal husbandry;secondly,a demonstration park of low-carbon livestock breeding should be established;thirdly,establish a interregional carbon emissions trading system;at last,optimize the allocation of resources and promote the coordinated development of animal husbandry.

Key words: carbon emissions from animal husbandry, production efficiency, economic efficiency, fair, Xinjiang
