中文摘要：

采用变异系数和空间自相关等分析方法对我国华北地区5省市单位工业产值SO2排放量、SO2去除比例的差异大小和空间聚集特性进行了分析，并采用线性回归方法对未来几年发展变化趋势进行了预测，提出了相关建议。

英文摘要：

By using the variation coefficient variation analysis method together with the spatial autocorrelation method, the difference and the spatial aggregation characteristics of SO2 emission value per industrial GDP and the disposal ratio were analyzed. The linear regression model was also used to predict the trends in the next few years. At last, the conclusions were drawn and some suggestions were proposed.
