Abstract: Based on the climate comfort index model and the climate data of 9 meteorological stations in Urumqi and its surrounding areas from 1961 to 2020,the spatial and temporal change of climate comfort in the past 60 years were analyzed by using statistical methods and ArcGIS.The results show that:（1）The climate comfort index changes within a year showed “M”type with double peaks and double valleys in the plain area and“∩”type with single peak and single valley in the mountainous area.（2）Due to the combined effects of increased temperature and relative humidity,as well as reduced wind speed and sunshine hours,the climate comfort index in spring,autumn,and winter in the plain area was significantly increased（P=0.05） in recent 60 years,while it was significantly decreased in summer.The climate comfort index in mountain areas was significantly increased in summer and autumn,while the changes in winter and spring were not significant.（3）In the past 30 years（1991-2020）,compared with the previous 30 years（1961-1990）,the upper elevation limit of the more comfort climate zone in spring and autumn had increased by 100-150 m,and the area had increased by 950 km2,the less comfort climate zone and uncomfortable climate zone had increased by50-100 m towards higher altitude,their areas had decreased by 694-828 km2and 131-236 km2,respectively.In summer,the climate comfort zone had increased by 100 m towards high altitude,and its area reduced by 514 km2,the upper limit of altitude of the more comfort climate zone increased by100-150 m,and increased its area by about 718 km2,the less comfortable climate and uncomfortable climate zone had also increased by 50-100 m toward high altitude,with a slight decrease in areas.In winter,the situation that Urumqi belongs to the uncomfortable climate zone had not changed.
