摘　　要：运用份额偏离方法分析吉林省松花江流域内主要污染物年际变化,评估污染物类别、竞争力和结构特征.研究表明:1)研究期内流域整体环境污染物排放变化幅度不大,年均增长率为0.4%;2)污染强度呈下降趋势;3)从污染物类别看,样本城市既存在共性也存在差异性.共性表现在主要污染物均为工业SO2,差异性表现在污染物的结构组成不同.造成差异性的原因在于城市产业结构不同,农产品加工业和造纸业对污染物结构的形成影响最大.Using the shift-share deviation method we analyze interannual variations of the main pollutants in assess type, competitiveness, and structure characteristics. The results could be summarized as follows： 1） emissions changed slightly and annual average growth rate was 0.4% ;2）the pollution intensity decreased; and 3 ） in the four sample cities the main pollutants were S02 and the pollutant structures were different. The largest influence was from the agricultural products＇ processing industry and papermaking industry.
