太原市大气环境质量时空变化分析

Spatial and Temporal Variation Analysis of Atmospheric Environmental Quality in Taiyuan City

本研究利用太原市空气质量数据,分析太原市2013至2017年间大气环境质量的时、空变化及发展趋势.结果表明:太原市大气环境质量呈逐年好转态势,其空气质量综合指数呈逐年递减趋势,除二氧化氮外,各污染物浓度逐年下降;太原市市区的空气质量大致呈西北部空气质量最好,中部地区最差,并以太原市市区中部为中心大致呈同心圆状向外辐射,其空气质量由中心向外部逐渐变好.本研究的开展可为改善或治理太原市大气环境质量提供一些科学依据或支撑.

In this paper,the air quality data of Taiyuan City were used to analyze the time and space change and development trend of atmospheric environmental quality during the 2013~2017 years.The results show that the quality of atmospheric environment in Taiyuan City is getting better and the overall air quality index showed a decreasing trend,with the exception of dioxide,the concentration of the pollutants decreased year by year.The air quality in Taiyuan City is roughly the best in the northwest,the middle region is the worst,and the central part of Taiyuan City is the center of the urban area,the air quality is gradually getting better from the center to the outside.The development of this research can provide some scientific basis or support for improving or managing the atmospheric environmental quality of Taiyuan city.
