摘要
基于沈阳市2014年大气环境监测数据,分析空气质量随时间变化规律。对PM_(10),SO_2,NO_2的日变化、月变化、季变化规律进行统计并归纳分析,得出PM_(10)与NO_2的日变化曲线均呈现双峰型,NO_2最大值出现在20时左右,PM_(10)最大值出现在22时左右,最小值均出现在15时左右,两者的形成原因具有类似性。SO_2的日变化曲线呈现单峰型,最大值出现在8时左右,与PM_(10),NO_2的最小值出现时间相同,均在15时左右。PM_(10),SO_2,NO_2月浓度变化曲线均呈V型,污染物浓度在冬季达到最大值,在夏季达到最小值。
This paper analyzes the variation law of air quality with time, based on the data of atmospheric environ- ment monitoring in Shenyang in 2014. The daily variation, monthly variation and seasonal variation of PM10, S02 and NO2 were analyzed and summarized. The results showed that the diurnal curves of PM10 and NO2 showed bi- modal type, the maximum value of NO2 appeared at about 20：00, the maximum value of PM10 appeared at 22 o＇ clock, the minimum value of each other appeared at about 15 o＇clock, and the formation reason of them was sim- ilar. The diurnal variation curve of S02 showed a single peak type, the maximum value appeared at about 8：00, and the time of minimum of PM10 and NO2 was similar, which was reached at about 15 o＇clock. The monthly curves of PM10, SO2 and NO2 showed V-type, and the concentration of pollutants reached the maximum in winter and reached the minimum in summer.
