Spatial distribution of the national average time-sharing fraction of E&G for heating (FH) (IMAGE)
Caption
The blue column chart showed that in nontypical heating zones (Southeast and Central Southern China), the changing trend of FH kept increasing from 1992 to 2017, which was largely driven by economic growth. Then the red column chart represented the FH in typical heating zones (Northern and Western China) with no obvious changing trend in the study period. Lastly, the yellow one showed the FH in the Beijing-Tianjin-Hebei and Fenwei Plain with intervention policy rose significantly.
