太原市典型大气污染物时空分布及其成因分析研究

摘要

根据太原市2001年-2012年环境空气定点监测数据,采用分时段统计分析和GIS空间分析相结合的方法探讨了太原市主要大气污染物的时空分布特征,并分析了形成原因.结果表明,太原市环境空气污染物浓度呈逐年下降趋势,环境空气质量逐步改善,这与太原市积极转变经济结构,加强污染控制有直接的关系.但是,太原市自然气象条件和污染源格局都不利于环境空气质量的改善,太原市空气污染情况依然严峻.%According to the data of ambient air monitoring sites for 2001-2012 years, this study investigated the spatiotem-poral distribution of main air pollutants and reasons in Taiyuan by the bucketed statistics and GIS spatial analysis.The results in-dicated that the concentration of main air pollutants was decreased year by year and the air quality was gradually improved in Taiyuan.It mainly depends on transforming economic structure and strengthening pollution control.However, the natural weather conditions and pollution source patterns are unfavorable for improving air quality, resulting in air pollution is still grim in Taiyuan.
