Abstract: Global warming caused by carbon emissions has an obvious inhibitory effect on human being’social and economic activities. Expecially,agriculture and animal husbandry production which leads to carbon emissions is one of the important inducements for accelerating global warming. Whereas the huge pressure of carbon emission caused by agriculture-stock production,based on 15 categories of major carbon sources from agricultural land use,and animal husbandry, this study calculated the agriculture and animal husbandury carbon emissions in Xinjiang during 1993-2011,as well as all of the prefectures and cities in 2011. And by using Tapio decoupling model,it has analyzed the Xinjiang’s agriculture and animal husbandry carbon emissions’decoupling relationship with agricultural economic development. The results shows as follows:(1)Xinjiang’ s agriculture and animal husbandry carbon emissions in 2011 were 778.73 thousand tons,a 50.12% increase over 1993,resulting from agricultural land use,animal husbandry which respectively accounted for 53.16%,46.84% of total agriculture and animal husbandry carbon emissions.In relation to time-series change,carbon emissions displayed an obvious‘kept elevating-fluctuating uprising’phase- change characteristic. (2) In lateral view,the regional difference was clear. As for total agricultural and animal husbandry carbon emissions,Kizilsu Kirgiz Autonomous Prefecture,Altay Prefecture and Counties Direct Under Ili Prefecture produced higher carbon emissions more than 600 thousand tons. Hotan Prefecture,Tacheng Prefecture,Aksu Prefecture and Kashgar Prefecture’ agricultural carbon emissions lay between 300-600 thousand tons. Changji Hui Autonomous Prefecture,Bayangol Mongol Autonomous Prefecture,Bortala Mongol Autonomous Prefecture,Hami Prefecture,Turpan Prefecture and Urumqi City produced lower carbon emissions less than 300 thousand tons.In all,the major areas of agriculture and animal husbandry production are the main source of carbon emissions. (3)As for the structure carbon emissions of agriculture and animal husbandry,based on the different carbon emissions,all the prefectures and cities were divided into three types:Bortala Mongol Autonomous Prefecture,Bayangol Mongol Autonomous Prefecture and Aksu Prefecture belong to land use dominant. Urumqi City,Hami Prefecture,Counties Direct Under Ili Prefecture,Altay Prefecture,Kizilsu Kirgiz Autonomous Prefecture,and Hotan Prefecture are the type of animal husbandry dominant. Turpan Prefecture,Changji Hui Autonomous Prefecture,Tacheng Prefecture and Kashgar Prefecture belong to composite factors dominant.(4) In relation to agriculture and animal husbandry intensity,in general,it presents obvious difference among all of the prefectures and cities in Xinjiang. To be specific,northern Xinjiang was the highest, followed by southern Xinjiang, and the east Xinjiang was the lowest. (5) The result from Tapio decoupling model shows that: it was an evolution process from weak alternating negative strong decoupling,to stationary weak decoupling,and changed into strong decoupling,indicating that some certain results have been achieved in agricultural carbon emission reduction during recent years. The conclusions of this paper have certain significance for supplementing the research of the issue about Xinjiang agricultural carbon emissions.
