利用江苏省2008－2013年24个站的酸雨监测资料，分析出2008－2013年江苏省酸雨的强度和发生频率都有下降趋势，秋冬季酸雨发生频率高，夏季最低。基于信息扩散理论对全省酸雨进行风险评估，结果发现：年降水pH值和酸雨发生频率在不同风险水平分布特征较为一致，呈西北－东南逐渐增强趋势；年降水pH值80％的可能介于4.5～5.6之间，呈弱酸性；淮河以南地区酸雨发生频率的风险为40％的概率超过90％。

Data of acid rain from 24 stations during 2008-201 3 are used to analyze the trends of acid rain in Jiangsu Province.It is shown that the intensity and frequency of acid rain are decreasing within the recent 6 years and the frequency is highest in autumn and winter and lowest in summer.The acid rain risk of the province is eval-uated based on information diffusion theory.The results indicate that:the distribution characteristics between the pH value of precipitation and the frequency of acid rain is consistent in different level of risk and it increases gradu-ally from Northwest to Southeast.The pH value of annual precipitation is between 3.8 and 4.5 with about 80%probability and it presents weak acidity.There is more than 90% probability that the acid rain is with 40% risk level in South of Huaihe River.
