Abstract Under the background of rapid urbanization, the original urban energy system has changed significantly. The anthropogenic heat flux play an important role in the urban energy system. In this paper, the source inventory method is selected to estimate the anthropogenic heat flux in Beijing. The results show that the total amount of AH emissions in the main zones was between 1.1×10 18 J and 1.26×10 18 J from 2007 to 2016. The structure of anthropogenic heat in Beijing also changed significantly during last ten years. The contribution of anthropogenic heat increase from 39.6% in 2007 to 57.3% in 2016, while the contribution of industrial sector decrease from 42.7% to 27.6%. The contribution of transportation have not changed significantly. The contribution of human anthropogenic heat increase from 2.6% in 2007 to 4.2% in 2016.
