  • 摘要: 选择石家庄市区代表性路段作为研究对象，对其交通环境空气中NOx的污染水平进行现状监测。基于Matlab软件建立拟合模型，对下一时期的NOx污染趋势进行预测。结果表明，石家庄市交通环境中NOx小时浓度介于0.047~0.237 mg/m3之间，呈早晚高，且下午明显低于上午的日变化规律；NOx日均浓度介于0.076~0.211 mg/m3之间，其浓度与车流量呈明显的正相关性。利用matlab软件建立的ARMA模型能够较好地预测道路交通环境空气中NOx的浓度变化趋势。
    Abstract: The representative roads in Shijiazhuang were selected as the research objects,the NOx pollution level in the road traffic ambient air was monitored.The fitting model was created by the Matlab software,then the pollution trend of NOx for the next period was forecasted.The results showed that the hourly average concentration of NOx in Shijiazhuang road traffic ambient air ranged from 0.047 to 0.237 mg/m3,the daily variation presented that the NOx concentration was high in the morning and in the evening,and the concentration in the after-noon was significantly lower than the one in the before-noon.The daily average concentration of NOx ranged from 0.076 to 0.211 mg/m3,and it had a significant positive correlation with the road traffic flow.The ARMA model established by the Matlab software could better predict the concentration variation trends of NOx in the road traffic ambient air.
