摘　　要：以福建省近年来降水监测数据为基础,分析了主要城市降水中致酸离子组成及沉降量现状,认为降水中的酸性物质是以硫酸盐为主,近年来硫酸根离子沉降量基本稳定;二氧化硫排放量、外省排放源、气象条件、土壤酸碱性、点位布设等因素对降水致酸离子沉降量有影响.Monitoring data about the component of precipitation of recent years was used to analyze acid caused ions, together with the present status of ions sedimentation through precipitation in the main cities of Fujian Province. It was found that the major part of acidic substance in the precipitation came from sulfate, and the total sedimentation of sulphate ions was basically stable in recent years. The calculation of sedimentation of acid caused ions through precipitation was not only affected by real sulfur dioxide emissions inside and outside the province, but also by other factors, such as meteorological conditions, background value of acidity and alkalinity of regional soils and spots arrangement.
