2001年~2004年郑州市大气污染现状调查与分析

目的分析郑州市大气污染原因,提出大气污染的对策。方法对2001年至2004年郑州市空气质量自动监测数据进行统计分析、利用环境质量指数法进行评价。结果按年均浓度评价,各年年均浓度均超过了国家二级标准,空气质量为三级。2002年大气污染最为严重。各年污染结构:PM10为首要污染物,SO2、NO2污染状况随年度变化呈上升趋势。年度内数据显示:春冬两季污染较为严重,明显高于夏秋两季。结论郑州市大气污染仍属于煤烟型污染,建议环境监管部门继续加强大气污染防治工作,特别是冬春两季的监测和治理。

The investigation and analyse of the air quality in Zhengzhou city from 2001 to 2004

Objective To analyzing the cause of the air pollution in Zhengzhou.Methods By the means of environment quality index,the air monitoring data of Zhengzhou from 2001 to 2004 is analyzed and evaluated.Results PM_(10) is the primary pollutant,The yearly average concentrations of SO_2、NO_2 grow year by year.As a whole,the air quality of Zhengzhou city is not deserved to be optimistical.The air quality in 2002 is significantly worse than that of the other 3 years,and the pollution of the air in Spring and Winter is more serious than that in Summer and Autumn.Conclusions The air pollution type of Zhengzhou is soot pollutions,So the enviornment monitoring department are suggested to strengthen the work of air prevention and cure,especially the air monitoring in sping and winter.
