利用1961—2013年广西90个地面观测站资料，分析近年广西霾日数和雾日数的时空变化特征。结果表明，1961—2013年广西霾日出现了显著的增加变化趋势，平均每10年增加4.5 d；广西雾日出现了显著的减少变化趋势，平均每10年减少0.6 d。霾和雾气候变化发生的原因与广西气温升高、相对湿度减小和风速减小有密切关系，城镇化发展和人类活动排放污染物增加也是可能原因之一。

Using the observation data from 90 stations in Guangxi from 1961 to 2013, the spatial and temporal variation characteristics of haze day and foggy day were analyzed. The results showed that haze day in Guangxi during 1961-2013 was increasing by 4.5 d/10 a, and foggy day was decreasing by -0.6 d/10 a. The climate change of haze and fog was closely related to the rising temperatures, decreasing relative humidity and wind speed in Guangxi, urbanization develop-ment and more emissions from human activities might be also one of the caus-es.
