摘要
空气质量指数是一种评价大气环境质量状况简单而直观的指标,可用于大气环境质量评价以及污染控制和管理。本文利用呼和浩特市PM2.5监测点数据和气象数据,利用空气质量指数法进行空气质量分析,用逐步回归法对影响空气质量的主要因素进行分析,并分析气象因素对空气质量的影响。得出影响呼和浩特市城区空气质量的主要因素是PM2.5、PM10、NO2和SO2,且寒冷、空气相对干燥和风大对空气质量会产生显著性的影响。
Air quality index is a kind of evaluation index of atmospheric environment quality condition,and is simple and intuitive,and can be used for atmospheric environment quality assessment and pollution control and management. In this paper,air quality index was used for air quality analysis with the Hohhot PM2. 5 monitoring data and meteorological data,and stepwise regression method was used to analyze the influencing factors of the quality of the air,and analyzed the influence of meteorological factor on air quality.The results shows that the main affecting factors of Hohhot urban air quality are the PM10,PM2. 5,NO2 and SO2,and the weather cooling,air dried and wind speed increasing will generate significant on air quality.
