选择位于长江南岸的铜陵市为研究区域，利用2007～2010年空气污染物浓度监测数据与气象要素观测资料，分析二氧化硫（SO2）、二氧化氮（NO2）和可吸入颗粒物（PM10）浓度的日变化特征及其与气象要素之间的关系。结果表明，铜陵市空气污染物浓度和气象要素的日变化主要有“单峰单谷型”和“双峰双谷型”两种，SO2和PM10的日变化规律空间差异不显著，NO2的日变化存在明显空间差异。主要污染源附近的监测点，浓度日变化规律与气压、相对湿度和气温3个要素日变化之间存在相关性，而与风速、降水的日变化规律无关。周边无污染物排放的监测点，浓度日变化规律不仅与气压、相对湿度和气温日变化存在显著相关，还与风速呈反向相关关系。对于周边虽有部分污染源，但不是区域内的主要污染源的监测点，浓度日变化与气象要素之间无统一的相关性。

Using the monitoring data of atmospheric pollution and meteorological data from 2007 to 2010 , the concentration diurnal variations of atmospheric pollutants (including SO2 ,NO2 and PM10 ) in Tongling City were analyzed ,and the relationship between the diurnal variations of atmospheric pollutants and meteorological factors was studied .The results show that the diurnal variations of atmospheric pollutant concentrations and meteorological factors can be classified into two types ,“single pink and single valley type”and “double pinks and double valleys type”.There is no spatial variation in SO2 and PM10 ,while NO2 exhibited obvious spatial variation . For areas near the pollution source , pollutant concentration is correlated with atmospheric pressure ,relative humidity and temperature ,but not with wind speed .For the observation points free from pollutants ,the relationship of pollution concentration variation and meteorological factors is similar to the area near the pollution source , and the pollution concentration variation is reversely correlated with wind speed .The other observation points of Tongling City ,which are not included in the two ,showed little relationship between pollutant concentration variation and meteorological factors .
