Climate change caused by greenhouse gas emissions has greatly affected the world. It has become the common goal of countries worldwide to address climate change, reduce GHG (greenhouse gases) emissions, and implement sustainable development strategies. China has proposed that by 2030, its CO 2 emissions per unit of GDP will have decreased by 60-65% compared with emissions in 2005. In addition to the second and third industries, agriculture is also an important source of GHG emissions [1-3].

Agricultural GHG emissions of CH 4 and N 2 O account for 50% and 92% of China's total CH 4 and N 2 O emissions, respectively [6]. Although agriculture is one of the main sources of anthropogenic greenhouse gases on earth, it also has a strong carbon sink function, which has great potential for greenhouse gas absorption. On the one hand, forests are the first recognized ones with carbon sinks. On the other hand, crops absorb much CO 2 through photosynthesis, and the carbon content can reach 43-58% of total biomass [7] . Moreover, the potential of carbon sequestration in cultivated land is huge, Pol. Abstract Agriculture has the dual attributes of being a carbon source and a carbon sink. The agricultural carbon compensation mechanism is important for increasing agricultural carbon sink and reducing agricultural carbon emissions. However, there is no specific entry threshold for the implementation of agricultural carbon compensation in China. Taking the two indicators of agricultural carbon sink level and agricultural carbon emission intensity as the basic indicators, and taking the regional average agricultural carbon sink level and the regional average agricultural carbon emission intensity as the baseline, we established the agricultural carbon compensation area selection process. According to the agricultural carbon compensation area selection process, the results obtained in Hotan Prefecture were reasonable. The result of selection accorded with the actual situation of agricultural carbon emission and agricultural carbon sinks in Hotan Prefecture.
