摘　　要：利用徐州市钢铁行业高分辨率排放清单,采用空气质量模式WRF-CALPUFF模拟并分析2017年徐州市钢铁行业大气污染物在冬、夏季对大气国控站点空气质量的贡献。结果表明,2017年徐州市钢铁企业排放主要大气污染物对大气国控点的ρ(PM2. 5)贡献最大达到10. 80μg/m3,对桃园路、铜山兽医院影响较大,其中一家企业的ρ(PM2. 5)贡献值就占了14家钢铁企业总贡献值的44. 33%;冬季的ρ(PM2. 5)贡献值总体上高于夏季,但不同钢铁企业在夏季和冬季对空气质量造成的影响存在一定的差异性,其中有5家企业在冬季的ρ(PM2. 5)贡献值明显高于夏季,而有2家企业的ρ(PM2. 5)贡献值在夏季高于冬季。Using the high-resolution emission list of Xuzhou iron and steel industry, the air quality model WRF-CALPUFF was used to simulate and analyze the contribution of atmospheric pollutants in Xuzhou Iron and Steel Industry to the air quality of atmospheric control points in winter and summer. The results showed that in 2017, the main atmospheric pollutants emitted by Xuzhou iron and steel enterprises contributed to a maximum concentration of PM 2.5 of 10.80 μg/m 3 to the atmospheric control points, which had a great impact on Taoyuan Road and Tongshan Veterinary Hospital. Among them, the contribution of one of the companies to the air quality of atmospheric control station accounted for 44.33% of the total contribution of 14 steel companies. From a seasonal perspective, the ρ （PM 2.5 ） contribution in winter was generally higher than that in summer, but there are some differences in the impact of different steel companies on air quality in summer and winter, the concentration of 5 companies were significantly higher in summer than in winter, while the contribution of 2 companies were greater in summer.
