    2014年-2015年兰州市环境空气质量分析

    Environmental Air Quality in Lanzhou City in 2014-2015

      摘要
    • 摘要:
      目的 分析2014年-2015年兰州市环境空气质量现状。
      方法 收集兰州市2014年-2015年PM10、PM2.5、NO2、CO、O3-1h和SO2的日均浓度监测数据，分析其年度、区域、采暖期、非采暖期分布特征并进行综合评价。
      结果 2014年-2015年兰州市环境空气质量有所改善，空气中的PM10、PM2.5、CO和SO2平均浓度下降，NO2和O3-1h平均浓度上升；除O3-1h外，其余空气污染物均是采暖期高于非采暖期；2014年-2015年市区西部总体污染物浓度较高；环境空气中主要污染物是PM10、PM2.5和NO2，2014年-2015年污染负荷系数PM10、PM2.5、CO、SO2下降，NO2和O3-1h上升。
      结论 2014年-2015年兰州市环境空气质量逐渐改善，采暖期与非采暖期空气污染物种类有所区别，针对兰州市首要污染物和污染区域等特点，应有针对性地制定改善空气质量的防治措施。

       

      Abstract:
      Objective To analyze the status of environmental air quality in Lanzhou city in 2014-2015.
      Methods The monitoring data on the average daily concentration of air pollutants, including PM10, PM2.5, NO2, CO, O3-1h and SO2 in Lanzhou during 2014-2015, were collected; the yearly, regional and seasonal characteristics in heating and non-heating season were analyzed, and then a comprehensive assessment was made.
      Results The environmental air quality in Lanzhou city was improved. The concentration of PM10, PM2.5, CO and SO2, was declined, the concentration of NO2 and O3-1h was increased. The concentration of air pollutants except O3-1h in heating season was higher than that in non-heating season. The total concentration of pollutants was higher in the western urban area of Lanzhou in 2014-2015. The major pollutants in environmental air were PM10, PM2.5 and NO2. The load factor of PM10, PM2.5, CO and SO2 were declined, but that of NO2 and O3-1h were increased.
      Conclusions The environmental air quality was improved gradually in Lanzhou in 2014-2015. The type of pollutants was different between heating season and non-heating season. According to the characteristics of major pollutants and contaminated areas, targeted measures should be taken to improve the quality of environmental air.
