Abstract: The summer temperature and human body comfort were calculated by inspection data come from 16 stations in Hulunbeir during 52 years from 1961 to 2012. By using the linear regression, change rate and deviation, the years, intra-season and spatial distribution of the human body comfort were analyzed. It turned out that the human body comfort in all regions of each period in summer of Hulunbeir was at an upward trend with global warming, and in a different range variation, with lowest temperature in midnight larger and highest temperature in daytime smaller. The special distribution declined along farming areapasturing area-forest area.
