天津市城区大气污染状况调研与分析

探究天津市城区大气污染状况,采集2016年4月至9月7个环境空气质量监测站实时发布的包括PM_(2.5),PM_(10),SO_2,NO_2,CO,O_3等指标数据,结合城区主干道路分布的地理位置,利用聚类分析、相关性分析等多元统计分析方法研究大气污染影响因素。分析表明,天津市城区大气的主要污染物为PM_(2.5)和PM_(10),二者对空气质量指数AQI影响显著。天津市城区大气污染状况每日变化呈早高晚低的趋势。

Investigating the air pollution condition in Tianjin and real-time collecting the PMz5 PMf0, SOs, NO2, CO and 03 data that was published by seven air quality monitoring stations from April 2016 to September 2016. The cluster analysis and the correlation analysis are applied to investigate the air pollution influencing factor with the urban trunk road location. The results show that the main air pollutants in Tianjin are PM2.5 and PM10, which have a notably effect on the AQI index. In addition, the degree of contamination shows a download trend in the whole day.
