This paper used CH4MOD model and emission factor method to calculate and analyze the CH₄ emission from agricultural activities in Yunnan province,and used scenario analysis to project the agricultural CH₄ emission in Yunnan province.The results showed that the total agricultural CH₄ emission in Yunnan province rose in fluctuation,followed by a sharp decrease,and then remained stable from 2010 to 2019,in which the emission from animal intestinal fermentation contributed the most.From 2010 to 2019,the agricultural emission intensity of CH₄ per unit agricultural added value in Yunnan province showed a downward trend,while the agricultural emission intensity per unit agricultural land area was fluctuating.The CH₄ emission from agricultural activities in Yunnan province was projected to be in upward trends under three scenarios from 2020 to 2029.Therefore,CH₄ emission reduction measures should be taken in rice cultivation,livestock and poultry breeding in order to achieve the goal of "double carbon" and build a beautiful China.
