摘要
利用2005年-2014年安阳市城市空气质量自动监测数据,采用Daniel趋势校验法对空气质量变化趋势进行分析,确定主要污染物,探讨影响空气质量变化的因素,提出改善空气质量的综合治理措施。结果表明2005年-2014年安阳市空气综合污染指数为2.60,属轻度污染,首要污染物为PM10,其次为SO2,冬季污染较重,呈现尘污染与煤烟型污染特征;大气污染物存在显著的空间差异性,西北工业区污染较重;总体上,综合污染指数、SO2、PM10均呈不显著上升趋势,NO2呈现显著上升趋势。
Based on the monitoring data of atmospheric environmental quality in Anyang City from 2005 to 2014,this paper conducted an analysis on air quality variation trends of Anyang City with the method of Daniel Test for Trend. According to this analytical data in this period,this paper tries to find out the key pollutant and the main causes in these years,as well as list some corresponding managements to improve the air quality. Results show that the air comprehensive pollution index was 2. 60,belonged to low- grade pollution,PM_(10) is the major pollutant followed by SO_2. Seasonal variation trend showed that the air quality in winter was worst. Moreover,the dust contamination and the coal smoking type pollutant were the remarkable feature. The spatial distribution of pollutants were significant differences,northwest industrial pollution was heavier. In general,the increase of the air comprehensive pollution index,SO_2 and PM_(10) were insignificant,the increase of NO_2 was significant.
