摘　　要：利用天气研究和预报(WRF)模式/大气排放源清单处理(SMOKE)模型/区域多尺度空气质量(CMAQ)模型系统模拟了天津市2016年12月16—21日红色预警期间一次重污染过程,并初步评估了应急预案响应措施的实施对大气污染物浓度的影响。结果表明,此次红色预警期间,天津市采取工业企业减排30%可使全市PM_(2.5)小时平均浓度削减3.0%～10.0%,机动车单双号限行可使全市PM_(2.5)小时平均浓度削减3.0%～5.5%,两种措施同时实施可使全市PM_(2.5)小时平均浓度削减5.0%～12.0%。重污染天气应急预案中响应措施的实施对抑制PM_(2.5)浓度上升起到一定效果,而且控制措施对污染峰值的削减效果更加明显。The WRF/SMOKE/CMAQ model was utilized to simulate a severe polluted process during the red alert in Tianjin from December 16 th to 21 th,2016,and the effect of emergency response measures on atmospheric pollutants was evaluated.The results indicated that：during the red alert period,the hourly PM（2.5） concentration would be reduced by 3.0%-10.0%if cutting the 30%industrial emission,it could be reduced by 3.0%-5.5% when taking odd-even traffic control measure,when the two measures were implemented simultaneously,5.0%-12.0% of hourly PM（2.5） concentration would be reduced.It was found that the implementation of the response measures in the emergency plan had a certain effect on the decrease of PM（2.5） concentration,and the control measures were more effective on the peak value of pollution.
