摘　　要：根据永福国家气象观测站(以下简称永福站)的风向风速、总云量、低云量等观测资料,采用一些公式和统计方法,从污染系数和混合层厚度的角度分析永福的污染气象条件。研究结果表明:永福站年污染系数为14.63,主要集中在NNE方位;混合层厚度较厚,大气扩散能力较好,有利于污染物的迁移扩散。According to the observation data of wind direction,wind speed,total cloud cover and low cloud cover of Yongfu national meteorological observation station(hereinafter referred to as Yongfu station),some formulas and statistical methods are used to analyze the pollution meteorological conditions of Yongfu from the perspective of pollution coefficient and mixed layer thickness.The results show that:the annual pollution coefficient of Yongfu station is 14.63,which is mainly concentrated in NNE direction;the thickness of mixing layer is thicker,and the atmospheric diffusion ability is better,which is conducive to the migration and diffusion of pollutants.
