    摘要:

    基于国家生态环境部发布的环境空气质量监测数据等资料,采取调查研究与量化分析相结合的方法,对关中地区西安、渭南、咸阳、铜川、宝鸡5市空气质量的总体特征和空间差异进行研究.结果表明:颗粒污染物普遍严重超标,其中PM2.5和PM10分别超标91%和77%;空气污染具有明显的季节性,冬季的首要污染物是PM2.5和PM10,夏季的主要污染物是O3;关中空气污染受地形、气象条件和工业排放、采暖、施工、道路扬尘、汽车尾气等人类活动综合影响,大气污染具有相似性,同时表现出一定的差异性.

    Abstract:

    Based on the environmental air quality monitoring data released by the Ministry of Ecology and Environment of the People's Republic of China and by using investigation and quantitative analysis methods,the overall characteristics and spatial differences of air quality in the five cities of Xi'an,Weinan,Xianyang,Tongchuan,and Baoji in the Guanzhong area were analyzed in this study.The results showed the following.(1) The particulate pollutants generally exceeded their standards significantly,with PM2.5 and PM10 exceeding the standards of 91% and 77%,respectively.(2) The air pollution has obvious seasonality,as the primary pollutants in winter are PM2.5 and PM10 and the major summer pollutant is O3.(3) Air pollution in the Guanzhong area is affected by human activities such as topography,weather conditions and industrial emissions,heating,construction and road dust,and automobile exhaust.The air pollution has similarities and shows some differences.
