选取了2001—2014年的相关数据,分析了江苏省水泥制造业的经济发展、资源能源消耗和污染物排放特征,同时对行业经济发展与大气环境污染变化进行了相关性分析。结果表明,2001—2014年,江苏省水泥制造业工业总产值呈现波动增加趋势,工业煤炭消费量呈现波动增加趋势,投入产出比呈现逐年波动上升态势;SO2的排放强度呈现波动下降的趋势,低于全省平均水平;烟粉尘的排放强度波动下降,高于全省平均水平;NOx的排放强度呈现波动上升的趋势,高于全省平均水平;SO2与烟粉尘排放量与GDP均高度呈负相关,回归曲线模拟基本类似U型的左半段,随着GDP的增加,SO2和烟粉尘的排放量呈现下降趋势。 |

Abstract: |
Based on the data of 2001—2014, this paper analyzed the economic development, resources and energy consumption, and the characteristics of pollutant emissions of cement manufacturing industry in Jiangsu province. At the same time, the correlations between industrial economic development and environmental pollution were analyzed. The results showed that the total industrial output value and coal consumption of cement manufacturing industry in Jiangsu province presented a fluctuating increase trend from 2001 to 2014, and the input output ratio was gradually rising year by year. The emission intensity of SO2 showed a downward trend, which was lower than the provincial average. The emission intensity of smoke dust and NOx fluctuated downward and upward, respectively, both of which were higher than the provincial average. SO2and smoke dust emissions were highly negatively correlated with GDP, and the regression curves were similar to the left half of the U model, that was, emissions of SO2and smoke dust decreased with the increase of GDP. |
