2013年及2014年两年大连市污染天气中，首要污染物为PM2．5的天数占96%。2014年大连市区空气中可吸入颗粒物PM10的年均值为85μg/m3，细颗粒物PM2．5的年均值为53μg/m3，均超出国家标准限值。笔者通过对市区各监测点位颗粒物监测结果及典型污染过程进行分析，定性得出施工等引起的各类扬尘、机动车保有量的不断攀升、本地工业及冬季燃煤、不利的气象因素以及所处偏西和西南风向等造成了大连市区空气中颗粒物的污染。

In recent two years, the primary pollutant of 96% pollution days was PM2.5 in Dalian city. The annual average value of PM10 was 85 μg/m3 while the value of PM2.5 was 53 μg/m3. Both the two values exceeded relevant national standard. In this paper, pollution causes of particulate in Dalian air was studied qualitatively according to the analysis of monitoring data of urban air monitoring sites and typical pollution process so as to provide environmental management basis for the city.
