Based on the data from December 2009 to January 2011 in Shijiazhuang City,the correlation between atmospheric particles and visibility was studied by using the method of correlation analysis. The results indica-ted that relative humidity was significantly negatively correlated with visibility,however it had a lower correla-tion with the concentrations of particle mass. The correlation between the mass concentration of atmospheric particles’ and its visibility was negative, especially in the range of 0. 43~0. 65μm granular the correlation was significant.%运用计量地理学相关分析的方法,以石家庄市2009年12月~2011年1月数据为例,研究大气颗粒物与能见度变化的相关性.研究结果显示：相对湿度与大气能见度呈显著负相关,与颗粒物质量浓度相关性较差；大气颗粒物质量浓度与能见度之间呈负相关,[0．43,0．65)μm粒径范围内二者相关性较显著.
