摘　　要：利用2013年哈尔滨市环境监测资料及气象资料,分析了4种主要污染物(PM_(10)、PM_(2.5)、SO_2、NO_2)的时空分布特征及各种气象条件对城市大气污染的影响。结果表明:风速在采暖期对污染物浓度的影响尤为显著,相关系数达-0.87;混合层高度对雾霾天气形成影响较大,PM_(2.5)浓度与混合层高度呈现负相关;气温、气压、降水与PM_(2.5)浓度均有较好相关性,哈尔滨市污染物特征受气象条件影响较大。In this paper, the spatial-temporal distribution characteristics of four main pollutants （PM10, PM2.5, SO2 and NO2） and the impacts of various meteorological conditions on urban air pollution were analyzed by use of the environmental monitoring and meteorological data of Harbin in 2013. The results showed that wind velocity affected the pollutant concentration dramatically during the heating period, with the correlation coefficient of -0.87. Mixing layer height had a greater impact on the formation of haze weather, and the concentration of PM2.5 was negatively correlated with it. Temperature, pressure and precipitation had good correlation with the concentration of PM2.5. Therefore, the air pollution characteristics of Harbin were greatly influenced by the meteorological conditions.
