The relationships between monthly average concentration of atmospheric pollutants, meteorological factors and sulphation rate of 2009 were investigated. It was found that sulphation rate is not noly depend on the concentration of SO2, but also significantly associated with PM10 , for the surface of PM10 is play an important role for oxidation of SO2. Pressure and relative humidity have a positive role to the rate of sulfation. H2O(g)in the air has the ability to condense pollutants, and the rate of sulfate is reduced by precipitation scoured the pollutants. Therefore, the rate of sulfate is decided by H2 O ( g) in air rather than precipitation, the diffusion and dilution of pollutants were impacted by the Temperature and wind speed, which is also constraints the rate of sulfate.%对硫酸盐化速率与大气中污染物质浓度和气象因素的分析结果表明,硫酸盐化速率不仅取决于SO2的浓度,还与PM10显著相关,是因为PM10表面为SO2的催化氧化提供了载体.气压和空气相对湿度对硫酸盐化速率有积极的促进作用,空气中的气态H2O具有凝结污染物质的能力,而降水对污染物质的冲刷效应降低了硫酸盐化速率.影响硫酸盐化速率的是空气中气态H2O而非降水.气温通过影响逆温层和风速共同影响着污染物浓度的扩散和稀释,从而决定着硫酸盐化速率的增减.
