摘要
为了了解渭南市大气污染成分特征及渭南市大气环境质量,对2008—2013年6年来渭南市区大气中SO_2、NO_2、PM_(10)的浓度变化进行了分析。结果表明:3种成分每年1—5月份平均浓度呈明显下降趋势5—9月份基本不变,10—12月份呈明显上升趋势。统计分析结果表明:除2008年外,2009—2013年每年大气质量达标天数在300天以上,均达到国家环境大气质量二级标准。渭南市政府倡导的"低碳环保"政策及采取的一系列措施对控制渭南市大气环境污染,提高其环境质量取得了一定的效果,但渭南市区大气环境污染的预防工作还需进一步加强。
In order to know-composition characteristics of air pollution and atmospheric environmental quality in Weinan, concentration variations of Weinan urban atmospheric SO2 , NO2 and PM10 were analyzed from 2008 to 2013. The results showed that the average concentration of three kinds of matter w,as significantly decreased from January to May each year,it basically unchanged from May to September and there was a clear upward trend presented from October to December. Statistical analysis results show that air quality standard number of days is more 300 days every year from 2009 to 2013, and reached the national ambient air quality stand-ards two.The policy of “low carbon environmental protection” and a series of measures have been used to control the weinan atmospheric environmental pollution, the environmental quality has obtained the certain effect in weinan city. But the prevention work of atmospheric environment pollution still needs to be further strengthened.
