摘    要:以南京市2004年-2008年降水监测数据为基础,对降水pH值、酸雨出现频率、阴阳离子组成进行了分段统计分析,探讨了南京市酸雨类型、变化规律及与气象环境关系,认为全市酸雨污染呈现减轻趋势。酸雨类型主要为硫酸型,酸雨污染秋季较严重,春季次之,冬、夏季相对较轻,其中9月份酸雨强度最强。降水中主要阳离子为Ca2+和NH4+阴离子则以SO4^2-为主。相对湿度与降水pH值呈负相关;风速与降水pH值呈显著的正相关。

关 键 词:酸雨  特征  变化趋势  南京

Abstract:Basis on the data on raining monitoring between 2004 to 2008 in Nanjing,the essay is to analyze the annual precipitation data,precipitation pH,the acid rain frequency and the composition of the anion and cation sub-statistical,to study the type and the developing law of the acid rain in Nanjing,as well as the relations between the weather conditions and the acid rain.From the research we can see that the effect of the acid rain pollution in the city is decreasing.The major acid rain pollutants in the city a...
Keywords:acid rain  characteristics  developing trend  Nanjing
