Abstract: In winter, indoor temperature is kept by district heating in northern China, while human feels cold indoors in southern parts of the non-district heating areas. The demand for heating is increasing as time goes on. To resolve the inconsistency between the existing air temperature-based heating zone and actual human heating feeling demand, this paper analyzed the spatial distribution of apparent temperature and redefined the kilometer-scale heating demand zone of China with ten-day winter climate dataset of 740 meteorology stations from 1971 to 2010, combining an apparent temperature model involved air temperature and air humidity. The result shows that the high heating demand region, including Highest and High heating demand, is larger than the existing heating region. And the extended high heating demand region is mainly located in the middle and lower reaches of the Yangtze River. Compared to existing heating zoning, which only considers air temperature, the new heating demand zoning result takes air humidity into account and reflects the human intuitive feelings of indoor cold and heat. This research may provide a scientific view for policy making of winter heating in various regions of China.
