摘　　要：根据１９９３年春季在京广线湖南段区域的观测结果，对酸性降水的污染状况、特征、成因及其来源进行了分析和探讨。结果表明：湖南地区春季降雨是“严重污染的硫酸型酸雨”；形成的机制与华南地区基本相同，污染物浓度是局地源贡献和外地源输送的叠加。Field measurements relating to acid rain were made in spring 1993 along Hunan Section,Jingguang Railroad.The pollution status,characteristics,sources and formation mechanism of acid precipitation were also studied and discussed.The results show that precipitation in spring in Hunan region is serious polluted acid rain with sulfuric acid;its formation mechanism is basically the same as that in South China;the concentrations of pollutants result from the contribution of both local sourecs and transport of external sources.
