[Objective] The carbon emission characteristics and driving factors of agriculture and animal husbandry in Qinghai Province were analyzed in order to provide theoretical and empirical evidence for Qinghai government on how to promote the scientific and orderly development of green and low-carbon development of agriculture and animal husbandry. [Methods] Carbon emissions from agriculture and animal husbandry in Qinghai Province during 2000—2021 were calculated from consumption of agricultural materials, livestock and poultry breeding, and crop growth. The methods of log-mean Dietrich index (LMDI) and Tapio decoupling models were used to examine the driving factors and decoupling state of carbon emissions from agriculture and animal husbandry, and the future development tendency from 2022 to 2035 was predicted. [Results] ① Carbon emissions from agriculture and animal husbandry in Qinghai Province showed a fluctuating upward trend during 2000—2021, with an average annual growth rate of 1.61%. Intestinal fermentation and manure management during livestock and poultry breeding were the main sources of carbon emissions, accounting for 94.94% of total emissions per year. ② The effect of the level of agricultural economic development and agricultural structure could increase the amount carbon emissions, with annual contribution rates of 39.40% and 16.53%. The effects of agricultural production technology and agricultural labor force could inhibit carbon emissions, with annual contribution rates of -37.45% and -6.63%. ③ On the whole, the decoupling state between carbon emissions and economic growth of agricultural and animal husbandry in Qinghai Province was characterized as weak decoupling. Agricultural production technology and agricultural labor force scale had weak decoupling effects, while agricultural structure had no decoupling effects. ④ From 2022 to 2035, the carbon emissions from agriculture and animal husbandry will show an increasing trend, with an average annual growth rate of 1.23%, and 0.38% lower than observed from 2000 to 2021. [Conclusion] Qinghai Province should increase carbon sequestration capacity of farmland soil, reduce the intensity of intestinal methane emissions from livestock and poultry products, strengthen the leadership of carbon reduction and fixation technology in agriculture and animal husbandry, and cultivate high-quality talents in agriculture and animal husbandry, and therefore to achieve low-carbon development in agriculture and animal husbandry.
