根据山西省阳泉市南煤集团西上庄煤电一体化项目的总体要求,拟用中尺度气象模式MM5耦合大气污染模式CALPUFF,对评价区域2005年4月的大气环境进行数值模拟.通过综合模式系统的模拟发现:该地污染源的排放对阳泉空气质量起决定作用;对SO_2的平均浓度贡献为47.05μg/m~3,对PM10的平均浓度贡献为20.37μg/m~3.本地点源的排放对SO_2的影响相对较大;对SO_2平均浓度的贡献可达36.93μg/m~3.该地面源排放对PM_(10)的影响相对较大,对PM_(10)平均浓度的贡献为14.63μg/m~3.外地点源排放对阳泉大气环境的影响较小,但在某些过程中外地点源排放的污染物通过区域输送对阳泉的宅气质量也会造成一定的影响.

Based on the integration project of South Coal Corporation, Yangquan City, Shanxi Province, aggregative model MM5 coupling CALPUFF was used to simulate the concentration of PM_(10) and SO_2 of full month in April, 2005. Results of aggregative model simulation showed that local emission had crucial influence on air environment in the City, with average concentration contribution to SO_2 of 47.05μg/m~3 and contribution to PM_(10) 20.37μg/m~3. Local point emission had relatively big impact on SO_2, with average concentration contribution up to 36.93μg/m~3. Influence of local area emis-sion was relatively high to PM_(10), with concentration contribution up to 14.63μg/m~3. Emission from surrounding regions were lower, but also had relatively significant influence in certain process through regional transportation.
