Abstract: In order to investigate the driving factors and decoupling effect of carbon emission from livestock industry under the goal of “double carbon”, the LMDI model was used to decompose the driving factors of carbon emission, and the Tapio decoupling model was used to analyse the decoupling relationship between the driving factors and carbon emission from livestock industry, and to test the decoupling efforts. The results show that: 1) From 2000 to 2020, the carbon emissions from animal husbandry in the Yellow River water recharge area of Gannan varied from 50.926×10⁴−118.736×10⁴ t, with an average annual growth rate of 1.72%. Maqu County, Xiahe County, Luqu County and other purely pastoral counties livestock carbon emissions accounted for the main position. 2) Economic development, population size is an important driving force for the increase in carbon emissions from animal husbandry, and the evolution of the "U" trend; intensity of animal husbandry, industrial structure and urbanization are the main factors in the development of low-carbon animal husbandry. 3) Intensity of animal husbandry production, urbanization factors are conducive to carbon decoupling, economic development and population growth factors mainly show the inhibitory effect of carbon decoupling, and most of the years the livestock production structure factors show the promotional effect of carbon decoupling. 4) During the investigation period, the sub-decoupling effort indexes corresponding to the industrial structure of the livestock industry and the efficiency of the livestock industry were positive in most of the periods, which means that the two are the main factors for the "decoupling" of the carbon emissions of the livestock industry in the recharge zone. "decoupling" or not. Finally, it is recommended to encourage the low-carbon green transformation of the traditional animal husbandry industry in terms of the transformation of the high-carbon production mode, the optimization of the industrial structure, and the technological innovation of low-carbon animal husbandry production, so as to help the ecologically rational development of the animal husbandry industry in the recharge zone.
