| 为在我国构建基于"浓度控制、总量控制、质量控制"相结合的大气污染防治新模式,结合国家《重点区域大气污染防治规划(2011-2015年)》及《淄博市环境保护"十二五"规划》的编制工作,利用CALPUFF空气质量模型模拟了淄博市及其周边地区大气污染特征,并基于模型模拟结果采用多目标线性优化方法估算了淄博市SO2、NOx、PM10这3项污染物的环境容量. 研究表明,淄博市大气污染受外来污染源影响大,外来污染源对淄博全市SO2、NO2、PM10年均浓度贡献率分别达26.34%、21.23%、14.58%. 淄博市各区县之间存在显著的相互影响关系,其中周边区县对张店中心城区的SO2、NO2、PM10年均浓度贡献率分别为35.96%、43.17%、17.69%. 淄博市不同区县的空间敏感性差异较大,其中周村区、桓台县、张店区、淄川区单位污染物排放量对城市空气质量的综合影响明显大于其它区县. 淄博市要达到《环境空气质量标准》(GB 3095-2012)的要求,SO2、NOx、PM10的环境容量分别仅为8.03×104、19.16×104、3.21×104 t. 因此,在山东半岛实施区域大气污染联防联控是确保淄博市空气质量达标的必要途径. |

| To develop a new pattern of air pollution control that is based on the integration of "concentration control, total amount control, and quality control", and in the context of developing national 《2011-2015 air pollution control plan for key areas》and 《Environmental protection plan of Zibo municipality for the "12th Five-Year Plan" period》, a simulation of atmospheric dispersion of air pollutants in Zibo City and its peripheral areas is carried out by employing CALPUFF model, and the atmospheric environmental capacity of SO2, NOx and PM10 is estimated based on the results of model simulation and using multi-objective linear programming optimization. The results indicates that the air pollution in Zibo City is significantly related to the pollution sources outside of Zibo City, which contributes to the annual average concentration of SO2, NO2 and PM10 in Zibo City by 26.34%, 21.23%, and 14.58% respectively. There is a notable interaction between districts and counties of Zibo municipality, in which the contribution of SO2, NOx and PM10 emissions in surrounding counties and districts to the annual average concentrations of SO2, NO2 and PM10 in downtown area are 35.96%, 43.17%, and 17.69% respectively. There is a great variation in spatial sensitivity of air pollutant emission, and the environmental impact of unit pollutant emissions from Zhoucun, Huantai, Zhangdian and Zichuan is greater than that released from other districts/counties. To meet the requirement of 《Ambient air quality standard》(GB 3095-2012), the environmental capacities of SO2, NOx and PM10 of Zibo City are only 8.03×104 t, 19.16×104 t and 3.21×104 t, respectively. Therefore, it is imperative to implement regional air pollution joint control in Shandong peninsula in order to ensure the achievement of air quality standard in Zibo City. |
