摘　　要：为提高大气污染问题的认知和管理水平,文章针对大气污染季节性特征展开分析,并划分潜在污染源区域。以邢台市为例,分析其季节性特征并识别潜在污染源。利用AQI数据和Spearman秩相关系数分析污染物间相关性,结合HYSPLIT模型从潜在源贡献因子和浓度权重轨迹出发,识别出大气污染的季节性特征,特别是秋冬季污染较重。模型分析显示,除邢台本地外,周边地区也对大气污染有显著贡献。因此,在治理邢台大气污染时,需特别关注这些潜在污染源区域,以提高管理水平和减少污染。To improve the awareness and management level of air pollution,this article analyzes the seasonal characteristics of air pollution and divides potential pollution source areas.Taking Xingtai City as an example,the study analyzed its seasonal characteristics and identify potential pollution sources.The seasonal characteristics of air pollution,especially heavy pollution in autumn and winter,were analyzed by using AQI data and Spearman rank correlation coefficient to analyze the correlation between pollutants,and by combined with the HYSPLIT model and the potential source contribution factors and concentration weight trajectories.Model analysis shows that in addition to the local area of Xingtai,the surrounding areas also make significant contributions to air pollution.Therefore,when dealing with air pollution in Xingtai,special attention should be paid to these potential pollution source areas to improve management level and reduce pollution.
