摘要
2013年大连市区PM10年均值为85μg/m3,同比升高28.8%,是近十年来PM10涨幅最大的一次。分析得出2013年PM10升高原因主要有:12013年气象条件较2012年不利于污染物扩散;22013年雾霾产生的PM10约占全年PM10总量的14%,同比上升11个百分点;3监测方法转变导致2013年PM10浓度升高7%左右;4本地污染源的影响。据此提出,大连市要完成PM10约束性指标,除了采取常规控制措施外,还需要从根本上改变能源结构,同时开展大气污染联防联控。
In 2013, the annual average concentration of PM10 is 85μg/m^3 in Dalian city, which increased 28. 8% compare to 2012. It is the biggest gains in 10 years. The increased reasons include four parts. The first, the meteorological conditions are more disadvantageous to the dispersal of pollutants compare to 2012. The second, the PM10 produced by regional haze accounts for about 14% of the total annual average, which increased 11 persents compare to 2012. The third, the change of monitoring method makes the concentration of PM10 increase by 7%. The last, it is affected by the local pollutions. According to these increased reasons, Dalian have to change the energy structure fundamentally and control with surrounding areas jointly.
