利用美国环保局开发的新一代空气质量模式系统Models-3,对2010年浙江省大气污染物进行数值模拟研究,并对SO2、NO2和PM10等大气污染物浓度的模拟结果与监测结果进行了对比分析。结果表明, Models-3系统能较好地反映浙江省的大气污染情况,模拟值与观测值的变化趋势具有较好的一致性,说明该模式能较好地进行大气污染物的分布特征和变化规律的研究。为定量分析电力行业多污染物协同控制与区域复合型大气污染之间的定量关系,评估不同控制情景下的环境质量效益,应用CMAQ空气质量模型分别对2010年基准排放情景和火电行业主要污染物(SO2、NOx和烟尘)的三套减排控制情景,评价环境空气污染物SO2、NOx、PM2.5和PM10状况进行模拟,评价污染物减排的环境效益。三套方案下PM2.5浓度下降比例分别为0.53%、0.55%和0.57%,其中重点区域浓度下降比例分别为4.36%、4.38%和5.9%;PM10浓度下降比例分别为0.40%、0.42%和0.65%,重点区域下降比例分别为3.42%、5.82%和8.16%;NOx浓度下降比例分别为12.4%和13.3%,重点区域下降比例分别为13.8%和16.9%;SO2下降比例平均为11.24%,其中重点区域下降比例为14.4%。SO2、NOx和烟(粉)尘协同减排对于浙江地区特别是重点区域的环境空气质量改善有着显著意义。

The air pollution of Zhejiang Province in 2010 was simulated using new generation air quality models system Models-3 developed by EPA, then the simulated and observed results of NO2, SO2 and PM10 concentrations were comparative analyzed. The results displayed the characteristics of atmospheric pollution, the simulated and observed values were consistency, which means that the model is able to better simulate the spatial distribution and variation features of atmospheric pollutants. In order to quantitatively analyze the relationship between the cooperative control of multi-pollutant in electric power industry and the regional complex air pollution, and assess environmental quality under different control scenarios, the 2010 benchmark emission scenarios and three different main pollutant emission control scenarios of thermal power industry, was simulated using the CMAQ model.The simulation results shows that the concentration of PM2.5 decreased 0.53%、0.55% and 0.57% respectively, as 4.36%、4.38% and 5.9% in key area. The concentration of PM10 decreased 0.40%、0.42% and 0.65% respectively, as 3.42%、5.82% and 8.16% in key area. The concentration of NOx decreased 12.4% and 13.3% respectively, as 13.8% and 16.9% in key area. The concentration of SO2 decreased 11.24% and 14.4% in whole province and key area respectively. There were signifi cant improvements in air quality by SO2, NOx and smoke collaborative emission reduction in Zhejiang Province.
