摘要
为进一步对广西壮族自治区梧州市典型月份的细颗粒物污染特性及来源进行分析,本研究利用设计特征雷达图的方式,直接表示大气污染在时间序列或空间上发生的变化特征,了解污染类型;另外,结合在线、离线监测手段剖析大气颗粒物的理化特点,分析采样期间梧州市ECOC等碳组分、颗粒物的主要来源,对梧州市大气颗粒物来源进行解析;再利用后向轨迹(Hysplit)聚类、潜在源贡献(PSCF)、浓度权重轨迹(CWT)三种气象模式逐步定量模拟梧州市周边潜在源对梧州市环境空气质量的影响,找到梧州市大气污染物受外来影响的主要区域,以期能够提前进行预警和准备。
In order to further analyze the characteristics and sources of fine particulate pollution in typical months in Wuzhou City,this study directly shows the change characteristics of air pollution in time series or space by designing characteristic radar map to understand the pollution types;In addition,combined with on-line and off-line monitoring methods,analyze the physical and chemical characteristics of atmospheric particulate matter,analyze the carbon components such as ECOC and the main sources of particulate matter in Wuzhou City during the sampling period,and analyze the sources of atmospheric particulate matter in Wuzhou City;Then,the three meteorological models of hysplit clustering,potential source contribution(PSCF)and concentration weight trajectory(CWT)are used to gradually quantitatively simulate the impact of potential sources around Wuzhou on the ambient air quality of Wuzhou City,and find the main areas of air pollutants affected by external factors in Wuzhou City,so as to make early warning and preparation in advance.
