山西省煤电行业的大气污染物排放占到全省排放总量的将近50％，山西省政府要求2020年前现役机组进行超低排放改造，鉴于煤电产业的排放特点，现役机组实施超低排放对于空气质量将会有较大的影响。研究建立现有燃煤电厂超低排放实施前和实施后的排放源清单，利用Calpuff 模型对现役机组执行超低排放空气质量改善效益进行模拟。结果显示，在原标准下现役燃煤发电机组对11个设区市市区的空气质量浓度贡献较大，山西省平均来看贡献相对较小，现役燃煤发电机组执行超低排放后，11个设区市市区现役燃煤发电机组的空气质量浓度贡献值有明显的下降，但山西省平均的下降值相对较小，“十三五”期间的大气污染防治需更多的考虑对其他源的控制。

In Shanxi province,50% of the air pol utants comes from coal-fired power plants.Shanxi provincial government has been asking al the service coal-fired power plants meet a ultra-low emission standard before 2020 , it's predictable that this policy wil improve the ambient air quality.It developes emission inventorys before and after the service coal-fired power plants maintain the ultra-low emission standard, and numerical y simu-lates the improvement of the ambient air quality, with the Calpuff model.Results indicate that there is an signifi-cantly decline of the pol ution contribution of service coal-fired power plants after maintaining the ultra-low e-mission standard in 11 districted cities, but non significant in the whole provincial area.To evidently improve the ambient air quality in the whole provincial area,other types of emission sources need more focus.
