| 摘 要： | 运用空气质量模型CMAQ模拟评估民用燃煤减排政策对京津冀大气中BaP污染状况的改进效果，模拟包括作为基准情景的2014年和低消减和高消减2个减排情景.模拟结果表明：基准情景下，京津冀BaP年均浓度为2.54ng/m3，超过国家空气质量标准（1ng/m3），呈现1月 > 4月 > 10月 > 7月的季节变化特点，反映出冬季供暖燃煤的影响；京津冀南部BaP浓度高于北部，推测原因是南部BaP排放量较高.1月削减民用燃煤排放量对降低该地区BaP浓度和沉降量效果最显著，低削减和高削减下，北京、保定、廊坊BaP浓度分别比基准情景降低30%和40%以上；4、7、10月削减民用燃煤排放量对该地区BaP浓度和沉降量的变化影响不大.京津冀民用燃煤联防联控能更加有效地降低该地区BaP浓度.

| Abstract: | The regional air quality model CMAQ was used to simulate and evaluate the effect of residential coal combustion emission reduction policies on atmospheric BaP pollution in Beijing-Tianjin-Hebei (BTH) region. The simulations included a base scenario (the year of 2014) and two scenarios of emission reductions. The simulation results:the annual average concentration of atmospheric BaP in BTH in the base scenario was 2.54ng/m3, which was more than twice of the national air quality standard (1ng/m3).The levels of monthly average concentration of atmospheric BaP were in the order:January, April, October, July, reflecting the impact of coal for heating in winter on atmospheric BaP concentration. The atmospheric BaP concentration of southern BTH region was higher than that of the northern region over BTH region, the reason was probably the higher BaP emissions in the south of BTH than in the north. The emissions reduction of rediential coal in January has the most significant effect on reducing concentration of atmospheric BaP and depotion.The concentrations of atmospheric BaP in January over Beijing, Baoding and Langfang in low (scenario1) and high (scenario2) were reduced by 30% and 40% respectively compared with the base scenario.The emissions reduction of rediential coal combustion in April, July and October had little effect on the changes of atmospheric BaP concentration and depotion. Taking control measures of residential coal consumption in all BTH region could more effectively reduce the concentration of atmospheric BaP concentration in this area. |
