摘　　要：通过对覆盖不同气候区的83个站点气象数据进行系统分析,研究了不同气候区供暖供冷度日数受气候变化的影响规律。结果表明:近20年来,空气相对湿度和太阳辐照度在我国大部分地区均呈上升趋势,而气温上升现象主要出现在中部地区和东北地区;近年气候变化造成我国寒冷地区和严寒地区的供暖度日数分别以每10年4.49%和2.41%的速率下降;夏热冬冷地区的供冷度日数以每10年19.22%的速率上升,而夏热冬暖地区供冷度日数则以每10年15.36%的速率下降。The influence of climate change on heating and cooling days in different climatic zones was studied through analysis the meteorological data of 83 stations covering different climatic zones systematically.The results show that in the past 20 years,the relative humidity and solar irradiance have been increasing in most parts of China,but the temperature rise mainly occurs in the central region and the northeast region.Along with the climate change,the heating days have decreased at a rate of 4.49%and 2.41% per decade in cold and severe cold regions.The cooling days have increased at a rate of 19.22% per decade in cold winter-hot summer region,but decreased by 15.36%per decade in warm winter-hot summer region.
