【摘要】 基于WRF-CAMx模型模拟天津市"十三五"期间大气污染防治措施对PM_2.5浓度改善的贡献,利用排放因子法计算大气污染防治措施对CO₂减排的贡献,在此基础上构建了协同效益指数评估污染防治措施对PM_2.5浓度改善和CO₂减排的协同效益。结果显示,"十三五"期间主要大气污染治理措施中,散煤治理、工业锅炉改燃并网和供热锅炉改燃并网措施对PM_2.5浓度改善的贡献最为明显,分别使PM_2.5浓度下降18.3%、13.6%、11.1%;工业锅炉改燃并网、钢铁企业退出、清洁能源利用措施对CO₂减排效果最为明显,分别减排834.71万、699.31万、300.05万t。综合来看,以工业锅炉改燃并网和钢铁企业退出措施对PM_2.5浓度改善和CO₂减排的协同效益较为显著。更多还原

【Abstract】 Based on WRF-CAMx model, the contribution of various measures to the improvement of PM_2.5 concentration in Tianjin during the 13 th Five-Year Plan period was simulated in this study. The contribution of some measures to CO₂ emission reduction was also calculated by using emission factor method. Based on the above research, a synergistic benefit index was constructed to analyze and evaluate the synergistic effect of each measure to the improvement of PM_2.5 concentration and CO₂ emission reduction. The results showed that the improvement of PM_2.5 concentration was significantly contributed by the control of coal, the fuel-changed and grid-connected of industrial boilers and heating boilers among the major air pollution control measures during the 13 th Five-Year Plan period, which reduced PM_2.5 concentration by 18.3%,13.6% and 11.1% respectively. The effective measures on the CO₂ emission reduction were the fuel-changed and grid-connected of industrial boilers, the withdrawal of steel enterprises, clean energy utilization, achieving 8.347 1 million, 6.993 1 million and 3.000 5 million tons of emissions reduction respectively. In summary, the measures of fuel-changed and grid-connected of industrial boilers and withdrawal of steel enterprises had the most obvious synergistic effect on the improvement of PM_2.5 concentration and CO₂ emission reduction.更多还原
