摘　　要：以福建省23个城市2004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,探讨了全省酸雨类型、分布特征及变化规律,认为全省降水pH年均值<5.6的城市比例呈逐年上升趋势,酸雨区主要分布在闽东南沿海,酸雨类型主要为硫酸型,3月份酸雨强度最强。On the basis of monitoring data of 23 cities over the whole province, statistics and analysis were carried out to describe the status quo of acid precipitation in terms of type, geographic distribution feature and the rule of changes. It was concluded that the number of city with annual average value of pH<5.6 tended to rise in the current years.
