2012—2016年安庆市空气质量状况分析及控制对策

Analysis and Control Measures of Air Quality in Anqing City from the Year of 2012 to 2016

利用安庆市环境空气质量监测点的数据,对安庆市近5年的空气污染特征进行研究。分析了该地区影响大气质量的主要污染物SO_2,NO_2,O_3,PM_(10),CO和PM_(2.5)浓度的时空分布特征。结果表明:安庆市近5年空气污染指数的年平均值都低于90;年优良天气率在70%到80%之间,天气优良频率在春夏两季相对较高,秋冬两季较低;主要污染物SO_2,NO_2,O_3,PM_(10),CO和PM_(2.5)都达到国家空气质量二级标准,总体的空气质量表现为良好;分析不同采样地点得到的污染物浓度,以及不同年份的季节变化规律,得出市区污染物的时空分布。最后分析了其影响因素并且提出了进一步改善空气质量的基本对策。

Based on the datum of air quality in Anqing,the characteristics of air pollution in Anqing from 2012 to 2016 are studied.The temporal and spatial distribution characteristics of the dominant 6 atmospheric pollutants（SO2,NO2,O3,PM（10）,CO and PM2.5）are analyzed.The results show that the average air pollution index in Anqing city in recent five years are less than 90;the rates of good weather between 70%to80%,the good weather occurring in spring and summer are more than in autumn and winter in number and in frequency;the dominant pollutants SO2,NO2,O3,PM10,CO and PM2.5reached national air quality secondary standard,and air quality is good overall;the pollution datum from different sampling locations and different seasons are analyzed.Finally,the influencing factors also discussed and the countermeasures and suggestions of the air quality are put forward.
