合肥市城市PM10污染成因及控制对策

利用合肥市4个空气自动监测站2001-2003年3年PM10的监测结果,从4个监测点3年PM10年均值、月均值和日均值超标率的变化情况对PM10污染时空分布特征进行了详细分析,并从气象条件、下垫面性质和污染物排放三个方面对PM10污染的成因进行了分析研究。同时针对PM10污染的形成原因和影响因素,提出了加大执法力度,控制燃烧排放;采取综合措施,减少扬尘污染;加强机动车尾气治理与监督管理;加强生态环境建设,以增加城市大气环境容量等一系列减轻合肥市城市PM10污染、改善城市空气环境质量的综合治理对策。

Study on the cause of formation and control countermeasures of PM10 pollution in urban area of Hefei City

This paper utilizes the monitoring data of inhalable particulate matter (PM_ 10 ) in 4 automatic monitoring station of Hefei City from 2001 to 2003.On the basis of analysis the temporal and spatial variation characteristics of PM_ 10yearly,monthly mean concentration and daily mean concentration ratio that surpass the national standard, study the main causes of the formation of PM_ 10 pollution from main factors:metrological condition,ground situation and discharge sources of pollutants.Finally put forward a series of comprehensive countermeasures for control PM_ 10 pollution and improve the environmental air quality in Hefei City,such as: control burning discharge by enhancing legalization,reduce dust pollution through integral measures,strengthen treatment and management for pollution from automobile vehicle exhaust emission,reinforce the construction of eco-environment to enlarge city air environmental capacity and so on.
