摘　　要：采用环境监测资料、污染源资料及计算污染物落地浓度与天气图、气象观测数据相结合的方法分析酸雪成因,确定此次酸性降雪属于硫酸型降雪,空气中碱性颗粒物较少,锅炉排放大量的酸性水蒸汽,本地锅炉SO2排放量大,与上风向来的水汽交汇形成酸性降水。By comprehensively analyzing the environmental monitoring data, the material about the source of pollution and calculating the concentration of fallen pollutants, as well as the weather chart and weather observation data, the cause of an acid snowfall in Dandong City is detected. It is found that the acid snowfall is a sulfuric acid one which is caused by SO2 that is emitted from boilers and water vapor that comes from the windward.

关 键 词：酸雪 SO2 酸性水蒸汽 天气条件
