| 摘 要： | 利用美国EPA开发的区域多尺度空气质量模式CMAQ对2008年8月发生在深圳地区的臭氧污染过程进行模拟,运用brute-force方法分析深圳机动车限行对臭氧浓度变化的影响.研究表明,CMAQ模式能较好的重现模拟期间臭氧的浓度水平和变化趋势;深圳机动车限行造成机动车的排放源削减会提高深圳城区臭氧浓度峰值,数值一般在10μg/m3以下。

| Abstract: | Community Multiscale Air Quality Modeling System(CMAQ),a 3-D regional chemical transport model,has been used to simulate a heavy O3 pollution episode in Shenzhen in August,2008.The brute-force method was used to investigate the motor vehicle restriction effect on O3 concentration in Shenzhen during the episode.Results indicated that CMAQ model produced a good performance on the levels and trends of O3 concentration.The reduction of motor vehicle emission because of motor vehicle restriction increased the peak value of O3 concentration in Shenzhen,with the value below 10 μg/m3 in the episode. |
