摘　　要：文章利用1992-2008年17年福州市酸雨观测资料，分析了福州市酸雨的时间分布特征，着重分析了2007-2008年福州市酸雨的若干特点，以及与福建省其他3个酸雨监测站对比情况。结果表明：2007-2008年福州市酸雨污染是有观测记录以来最严重的两年，也是福建省4个酸雨监测站中酸雨污染最严重的地方；2007-2008年福州市酸雨降水酸度明显加强，年均降水pH值首次连续两年达到强酸雨量级；酸雨和强酸雨的出现频率明显上升、出现日数明显增多，酸雨量与总降水量的比值逐年上升、增幅明显；17年来各项监测数据的最大值和次大值均出现在2007或2008年，且高于或远高于其他3个站对应的监测值。Based on the 17 years （1992-2008） observations of acid rain, the spatial features and characteristics （2007-2008 ） of acid rain in Fuzhou were analyzed. The results show that 2007-2008 was the period of severest acid rain on observation record in Fuzhou, and Fuzhou was the severest station in acid rain observation network of Fujian province. The acid intensity of rain in fuzhou between 2007 and 2008 increased obviously, and annual average pH value belongs to severe acid rain grade uninterrupted first time. The frequency of acid and severe acid rain increased evidently, and the proportion of acid rain in total rain increased year after year. The maximum and second maxima of acid rain observation data occur in 2007 or 2008, and the value was higher than other stations in Fujian.
