| 摘 要： | 大气污染问题是河谷型城镇目前面临的最严峻的挑战,利用典型河谷型城镇山西省灵石县2005-2009年的主要污染物SO2、PM10和NOx的浓度监测资料与同期的地面气象资料分析了其大气污染物的时空变化规律,研究分析了污染物的扩散、迁移、转化机制与污染机理,研究得出河谷地形与逆温影响是灵石县城大气污染严重的主要原因,并提出了合理、有效的改善河谷型城镇大气环境质量和大气污染综合治理的措施与对策.

| Abstract: | The problems of serious atmospheric pollution has become the greatest challenge faced by the river valley town.Based on the density of several kinds of main pollutants such as PM10,SO2 and NOx and ground meteorological data of Lingshi county(2005～2009),being a typical river valley town in Shanxi,the temporal and spatial change rules of atmospheric pollutants were stadied.By the analysis of the diffusion,move,transforming mechanism and atmospheric pollution mechanism of pollutants,the results shows that the river valley terrain,parasol cold lake effect,converse temperature layer depth and intensity are the major controlling factors of atmospheric pollution in Lingshi County.In addition,some countermeasures are put forward to economically,rationally and effectively improve the air quality and air pollution treatment of the river valley town. |
