| 摘要: |
| 以天津市2010年污染源普查数据中SO2、NOx及颗粒物排放数据以及各行业挥发性有机物调查核算数据为主要数据源，制作天津市大气污染物排放清单，用MM5模型模拟2010年天津市地区1、4、7、10月的气象场，通过CMAQ模型，设置不同计算情景，分析天津市p(03)变化与NOx及挥发性有机物的排放量变化关系。结果表明，天津市的O3生成处于VOCs控制区，随着天津市NOx减排力度的不断加大ρ(O3)可能呈上升趋势，在夏季，需要削减40%以上挥发性有机物，以避免ρ(O3)进一步上升。 |

| Abstract: |
| The SO2 and NOx emission data from Tianjin pollution source survey of 2010 and industrial volatile organic compounds estimation data were used as main sources to establish Tianjin air pollutant emission inventory. The meteorological fields of Tianjin Area in January, April, July, October 2010 were simulated using MM5. Finally, CMAQ model was used and several scenarios were designed to analyze the correlation ship between the O3 concentration change and NOx and VOCs emission change. The results indicated that O3 generation in Tianjin was limited by VOCs.O3 concentration might continue to increase when more and more NOx emissions were cut down, but VOCs reduction was beneficial to O3 control. In summer, more than 40% VOCs emission was needed to be cut down to avoid the O3 increase in Tianjin. |
