SO2 Air Quality Impact on Beijing and Surrounding Region From Power Plant Emissions in North China

  • 摘要: 采用MM5、Models-3/CMAQ耦合模型系统,模拟了河北、天津、山西、内蒙古4省市电厂源排放对北京及周边地区SO2a质量浓度影响.模拟结果表明,电厂源对华北地区SO2a年均贡献质量浓度高值多出现在电厂密集、污染物排放量大的地区,且从南到北呈递减趋势,北京城区、北京全市1月月均贡献质量浓度分别为7.63和7.13μg/m3,4月分别为5.54和5.37μg/m3,7月分别为3.02和3.68μg/m3,10月分别为7.49和7.53μg/m3,年均贡献质量浓度分别为5.92和5.93μg/m3,其中日均最大贡献质量浓度出现在1月,为30.1和19.1μg/m3,分别占国家空气质量二级标准的20.1%和12.7%.研究表明,华北地区电厂源排放对北京市SO2a空气质量影响是不能忽视的,能够促使和加剧北京市的大气环境污染.
    Abstract: An integrated MM5,Models-3/CMAQ modeling system was applied to study SO2a air quality in Beijing and its surrounding regions by the effects of power plant emissions from Hebei,Tianjin,Shanxi and Inner mongolia.The result of simulation indicated that high SO2a concentration was appeared in regions with high density of power plants and high emissions magnitude.SO2a concentration in Beijing was decreased from south to north,with monthly concentration of 7.63 and 7.13 μg/m3 in January,monthly concentration of 5.54 and 5.37 μg/m3 in April,monthly concentration of 3.02、3.68 μg/m3 in July,monthly concentration of 7.49、7.53 μg/m3 in October,and annual concentration of 5.92 and 5.93 μg/m3 in 2005,for urban and entire city of Beijing,respectively.The maximal daily concentrations of urban and entire city of Beijing were 30.1 and 19.1 μg/m3 in January,which were 20.1% and 12.7% of the class Ⅱ national air quality standard.Power plant emissions in north China induce or enhance air pollution in Beijing,which should not be neglected.
