摘要
本文对陕西省关中地区33个城市环境空气质量自动监测站点2015年全年的监测数据进行统计和研究,讨论了关中城市空气质量特征和主要影响因素。结果表明,关中地区城市间空气质量具有密切的相关性和整体性,影响关中城市群全年空气质量最主要的污染因子是可吸入颗粒物(PM10)和细颗粒物(PM2.5),首要污染物呈现出显著的季节变化规律。人类活动、气象因素以及地形特征是造成关中地区空气质量现状的主要原因。
In this paper,the monitoring data of 2015 coming from 33 urban air quality automatic monitoring stations in Guanzhong region of Shaanxi Province,China were collected and studied,and the urban air quality characteristics and main influencing factors in Guanzhong region were discussed. Results show that air quality is closely related with cities in Guanzhong region. The main pollution factors affecting air quality in Guanzhong region are respirable particulate matter（ PM10） and fine particulate matter（ PM2.5）.The primary pollutants show significant change with seasons.
