Abstract: Based on data of daily average temperature, average wind velocity and average relative humidity in 70 observatories in Anhui Province from 1961 to 2010, the spatial-temporal distribution of climate comfort degree was calculated by the model of climate comfort degree index. The comprehensive zoning and evaluation was done by using of spatial interpolation techniques of Geographic Information System. The results show that the temporal and spatial distribution of climate comfort degree is significantly different in Anhui. The climatic condition is relatively comfortable from April to October in general, yet uncomfortable in wintertime mainly from November to next March; the climate comfort degree in the southern part of the region is better than in the northern part. Since the 1960s, the annual climate comfortable days have obviously increased in general under global warming, and the linear increasing trend once mutated around 1986 at 95% level; however, the annual climate uncomfortable days have obviously decreased, and the linear decreasing trend mutated around 1997 at 95% level. Comprehensive zoning shows that the best comfortable climate regions are mainly located in the southern part of Jiangnan and areas along the Yangtze River; while the northeast of Huaibei Region, Dabie Mountains and mountainous areas of South Anhui are the most uncomfortable areas in terms climate.

Key words: Anhui Province, climate comfort degree, comprehensive zoning, spatial-temporal distribution
