摘要
对福州市2013年4月-2016年3月空气质量指数AQI(Air Quality Index)数据进行小时变化、逐日变化、逐月变化、季节变化、空间分布及其影响因素分析,探讨引起AQI时间变化及空间分布差异的原因,找出最重要的影响因子。结果表明,福州市AQI在夜间较低,白天由于人类最活动增强,AQI增大;四季中春、冬季AQI较高,夏秋季节次之;通过对首要污染物进行统计分析得到,NO2、PM2.5、PM10、O3对AQI的贡献大,空气质量达到优的天数表现为秋季>夏季>冬季>春季;福州市内各监测点中快安始终作为空气质量较为不好的监测点,而杨桥西路在四季中多表现为AQI较低,空气质量较好。
By analyzing air quality index（AQI） of hourly average changes,daily average changes,monthly average changes,seasonal changes,spatial distribution and impact factors from April 2013 to March 2016 in Fuzhou,the tendency of AQI changes over time was obtained,different spatial distribution of AQI was studied,and the causes of these changes were investigated for the purpose to find out the main impact factors. The results showed that AQI was lower during the night,however because of the increase of human activities during the daytime,AQI also increased. AQI was higher in spring and winter,and followed by autumn and summer. Through the statistical analysis of main pollutants,NO2,PM2.5,PM10,O3 were the largest contribution of AQI,and the air quality to achieve the best performance of the number of days was autumn summer winter spring. The air quality of Kuai＇an was always relatively worse compared with all of monitoring points in Fuzhou,while AQI of Yangqiaoxilu was lower and showing good air quality.
