利用重庆34个地面观测站1980~2012年气象资料，对重庆霾的空间分布、气候特征及其变化趋势进行了分析。结果表明：重庆霾日数空间分布呈现出西部多、东部较少、盆地多的特点；霾天气冬季最多，春秋季次之，夏季最少，12月最多，7月最少；20世纪80年代中期到90年代后期重庆霾日数总体较多，从变化趋势看，1980~1996年呈波动上升趋势，1997~2012年呈波动下降趋势，这与重庆以煤炭为主的能源消费结构、SO2排放量的变化等密切相关。

Based on the daily observational data of 34 meteorological stations from 1980 to 2012,including visibility,relative humidity, weather phenomena,precipitation,wind speed and so on,and the annual emission of SO2 and industrial dust during 1998-2012,the spatial and temporal distribution characteristics and climatic trends of haze days in Chongqing were analyzed. The results indicated that the haze days in Chongqing had been more in the western part which located in basin and less in the eastern part. The haze days were most in winter,the next in autumn and spring,and least in summer. The annual change of haze days during 1980-2012 was obvious, the haze days were generally more from the mid-1980s to the late 1990s,and showed a fluctuating upward trend during 1980-1996 and downward trend during 1997-2012,which was closely correlated to the consumption structure of energy focusing on coal as well as the emission of SO2 in Chongqing.
