基于2004-2011年广西14个设区市及部分县的降水监测数据，对降水pH值进行统计和空间插值，分析广西酸雨特征的变化趋势和时空分布状况，并探讨影响广西酸雨形成的主要因素。结果表明，2004～2011年，广西降水pH值年均值均小于5．6，酸雨城市比例自2007年起逐年下降；酸雨发生频率在25％以上的城市比例自2006年起逐年下降；2004-2007年，广西酸雨区域分布格局变化不大，自2008年起，广西酸雨区域面积呈现较大幅度的减少。广西的酸雨污染有所减轻，这与广西近年来对二氧化硫排放量的严格控制有关。

Based on the acid rain monitoring data of 14 cities and some counties in Guangxi Province during 2004-2011,the annual variation trend and temporal-spatial distribution of the acid rain were analyzed, and the influencing factors were explored. The results showed that the annual mean pH value was less than 5.6 during 2004-2011. The proportion of acid rain cities annually had decreased since 2007, and the proportion of acid rain cities with acid rain occurrence frequency being over than 25% had decreased gradually since 2006. During 2004-2007,the distribution pattern of Guangxi acid rain region slightly changed. The area of acid rain region in Guangxi dramatically decreased. The rigid control of the SO2 emission recent years in Guangxi is play an important role in the decrease of pollution caused by acid rain.
