| 摘 要： | 本文收集西安市2013年环境监测站发布的空气质量指数（AQI）及环境空气状况与监测月报资料,对空气质量等级、AQI变化情况、主要污染物浓度变化趋势及采暖期和非采暖期浓度比较进行分析.研究结果表明：西安市2013空气质量二级以上的达标率为37.8％,年均AQI值为151,SO2、NO2、PM10和PM2.5的月监测浓度变化趋势无显著意义,采暖期平均浓度均显著高于非采暖期平均浓度,PM2.5采暖期均值是非采暖期均值的3.09倍.由此可见控制SO2、NO2、PM10和PM2.5的排放是改善西安市空气质量的重点工作.

| Abstract: | The AQI changes, major pollutants concentration and the comparison between the heating and non - heating period were analyzed in this paper based on the air quality index and monthly data of environmental monitoring stations of Xi＇ an in 2013. The attainment rate of the air quality above grade Ⅱ was 37.8% of Xi＇an in 2013. The average annual value of AQI was 151. The monthly trend of SO2, NO2, PM10and PM2.5 was not significant, but the average concentration of heating period were significantly higher than non - heating period. The concentration of PM2.5 in heating period is 3.09 times in non - heating period. It is concluded that controlling the emissions of SO2 , NO2 , PM10 and PM2.5 is one of an important part for improving air quality in Xi＇an. |
