城市大气环境特征及气象条件影响因子的分析

Analysis of urban atmospheric environment characteristics and impact factors of meteorological conditions

本文应用数据及统计分析法探讨了城市大气环境特征及气象条件影响因子,发现某城市2017年空气重污染主要在初春及秋冬季,影响扩散污染物的气象条件同2016年大致相当,但2017年的空气达标天数明显高于2016年,重污染天数则明显低于2016年,重污染持续天数也明显减少,这说明该城市空气质量明显改善。

This paper discusses the characteristics of urban atmospheric environment and meteorological conditions by applying data and statistical analysis. It is found that the heavy air pollution in a city in 2017 is mainly in the early spring and autumn and winter. The meteorological conditions affecting the diffusion of pollutants are roughly the same as in 2016, but In 2017, the number of days of air compliance was significantly higher than that of 2016. The number of days of heavy pollution was significantly lower than that of 2016, and the number of days of heavy pollution was also significantly reduced, indicating that the city＇s air quality improved significantly.
