摘要:基于河南省2015—2016年AQI及首要污染物数据,从年、季节尺度分别探讨河南省空气污染首要污染物构成特征及变化过程,并借助聚类分析和空间自相关方法阐明其空间关联模式。结果表明:PM2.5是2015 —2016年河南省最常见的首要污染物,但其出现天数占比下降, O3出现天数急剧增加。首要污染物构成不同季节变化差异较大,冬季首要污染物PM2.5出现天数增多,污染物构成种类减少,春、夏、秋季首要污染物O3出现天数上升,尤其是夏、秋季节。 河南省空气污染天数及首要污染物在空间呈现一定的集聚特征,且集聚区域随时间变化差异明显。受城市社会经济、自然条件等因素影响,河南省城市首要污染物可划分为5大类。研究结果可为制定科学高效的空气污染联防联控策略及分类治理决策提供借鉴。

Abstract:Based on daily AQI and major pollutants data in 18 cities in Henan Province between March 2015 and February 2016, the characteristics of primary air pollutants composition and its change process were investigated on yearly and seasonal scale, and the spatial correlation model was clarified by cluster analysis and spatial autocorrelation method. The results showed that PM2.5 was the most common primary pollutant in Henan Province from 2015 to 2016, but the numbers of its occurence days decreased, and the occurrence days of O3 increased greatly. Composition of air pollutants varied extremely in different seasons. The number of occurrence days of PM2.5 as the major pollutant increased and the types of air primary pollutants decreased in winter,while the occurrence days of O3 as the major pollutant in spring,summer and autumn increased,especially in summer and autumn. The number of days of air pollution and the main pollutants in Henan Province showed a certain agglomeration characteristics in space, and the agglomeration areas varied significantly with time. Under the influence of social economy and natural conditions,the urban primary air pollutants in Henan Province could be divided into five categories.These findings could provide useful references for making scientific and efficient joint prevention and control strategies and classified governance decision.
