| 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.

| Abstract: | 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 SO2 and the pollutant structures were different.The largest influence was from the agricultural products’ processing industry and papermaking industry. |
