利用2009年7月至2010年6月辽宁中部城市沈阳、鞍山和本溪大气成分站能见度与颗粒物连续监测资料，分析能见度变化特征及其与颗粒物的相关关系。结果表明：辽宁中部各城市能见度具有明显的月和季变化，峰值出现在3月或5月，谷值出现在12月或1月；各城市的能见度与颗粒物 PM10、PM2.5和 PM1的质量浓度均呈负相关关系，但其最优拟合关系方程及决定系数 R2不同。从拟合方程来看，沈阳市雾霾污染时采用倒数曲线 y ＝b1＋b1 x 拟合效果相对较好，全年采用指数曲线y ＝b0 eb1x拟合效果较好；鞍山市采用对数曲线 y ＝b0＋b1 lnx 或指数曲线 y ＝b0 eb1x拟合效果较好，本溪市采用倒数曲线 y ＝b0＋b1 x 或对数曲线 y ＝b0＋b1 lnx 拟合效果较好。从决定系数 R 2来看，沈阳和本溪市能见度与颗粒物的质量浓度总体相关最好，鞍山市能见度与颗粒物质量浓度总体相关性相对较差。颗粒物细粒子 PM2.5和 PM1拟合的能见度效果较好，且在雾霾污染时拟合效果更好，说明细粒子对能见度的影响更明显。

Characteristics of atmospheric visibility and it relation with atmospheric particles had been studied using observed visibility and particle data from July of 2009 to June of 2010 at air component monitoring stations of She-nyang,Anshan and Benxi in Liaoning province.The results show that monthly variation is characterized with a clear peak value in March or May and low value in December or January.There is a significant negative correlation between visibility and particles mass concentration of PM10、PM2.5 and PM1 ,while their fitting equations and corre-lation coefficients are different.From the viewpoint of fitting equation,there is better fitting effect using the equa-tion y =b0 +b1 x when fog-haze weather occurs in Shenyang,while it is better using the equation y =b0 e b1x for the whole year.The fitting effect is better using the equation y =b0 +b1 lnx or y =b0 eb1x in Anshan and y =b0 +b1 x or y =b0 +b1 lnx in Benxi,respectively.From the viewpoint of correlation coefficient,it is the best in Shenyang and Benxi,while it is worse in Anshan.Visibility fitted by fine particles PM2.5 and PM1 is accurate,especially during a fog and haze process,thus it suggests that fine particles have more obviously impact on visibility.
