摘　　要：本文主要以河南省环境保护厅的监测数据为基础,通过对郑州市2013-2016年的空气质量的分析,得出郑州市2013-2016年的年际变化规律及年内变化规律。结果显示:郑州市在研究期间空气质量等级以Ⅱ、Ⅲ级为主,可吸入颗粒物(PM2.5、PM10)污染情况最为严重。硫化物(SO_2)、CO、臭氧(O_3)污染情况明显减少;NO_2污染情况呈加重趋势;在年内空气质量指数呈U型变化曲线,季节特征明显,夏季空气质量最好,冬季受城市采暖影响空气质量最差、污染最严重;同时,空气质量变化受到风力、风向和降水等气候条件的不同程度的影响,以及受机动车尾气污染和扬尘污染影响。This article is based on the monitoring data of Henan environmental protection department. Through the analysis of the air quality in Zhengzhou for 2013-2016 years, the annual change law of Zhengzhou city for 2013-2016 years and the changing law of the year are obtained. The results show that the air quality grade in Zhengzhou is dominated by class II and III during the study period, and the air quality can be inhaled. The pollution of particles（PM2.5, PM10） is the most serious. The pollution of sulphide（SO_2）, CO, and ozone（O_3） is obviously reduced; the situation of NO_2 pollution is aggravated; the air quality index has a U change curve in the year, the seasonal characteristic is obvious, the air quality is the best in summer, and the air quality is the worst pollution affected by the urban heating in winter. At the same time, the change of air quality is affected by different degrees of climate conditions such as wind, wind direction and precipitation, as well as the pollution of motor vehicle exhaust and dust pollution.
