徐州市环境空气质量综合评价

摘要

为了研究徐州市大气环境质量变化情况,深入了解污染大气的环境因子,选取2013年10月～2016年12月的监测数据,参照环境空气质量标准(GB3095—2012),将SO2、NO2、PM10、PM2.5、CO、O3作为评价因子.运用模糊数学方法对徐州市空气环境质量等级进行划分,并采用AQI指数评价法对污染程度做出评价.经过推理运算得出的综合评价结论为:徐州市空气质量逐年好转,主要污染物为细颗粒物(PM2. 5)、可吸入颗粒物(PM10).%In this paper, with the aims at studying the ambient air quality changes in the recent years in Xuzhou City and understanding the environmental factors affecting the air pollution, monitoring data from October 2013 to December 2016 was selected. According to the Ambient Air Quality Standards ( GB3095 －2012), indicators such as SO2, NO2, PM10, PM2. 5, CO and O3 were determined as the evaluation factors. Fuzzy theory was used to rank the air quality grade and AQI method was used to evaluate the air pollution degree. The results of comprehensive evaluation showed that the air quality in Xuzhou improved gradually year by year and the primary pollutants were PM2. 5 and PM10.
