利用三波段积分浊度仪和 Differerntial Optical Absorption Spectroscopy(DOAS)差分吸收光谱仪对南京北郊地区2009—2011年四季气溶胶散射系数和 NO 2进行观测，结合自动气象场观测数据，计算了南京北郊工业区四季的能见度消光因子贡献率.同时依据2011年5月—2012年4月的 PM2.5数据，分析了 PM2.5、相对湿度和能见度之间的关系，并得到了不同相对湿度和 PM2.5质量浓度下能见度的回归方程.结果表明：气溶胶散射消光贡献(βsa )最大且存在季节差异，冬季最高，夏季最低.PM2.5质量浓度在150~200μg·m-3时，霾发生概率最高，达到97.7%.相对湿度和 PM2.5质量浓度不同，影响能见度的因子不同.

Based on the aerosol scattering coefficient observed by the integrating Nephelometer in the north suburb of Nanjing in four seasons 2009 -201 1,combined with data of NO 2 mass concentration,visibility,the contribution of extinction factors were.calculated.According to data of PM2.5 mass concentration,the relationship of PM2.5 ,relative humidity (RH )and visibility were analyzed,regression equations of PM2.5 ,visibility relative humidity and temperature were calculated.Results show that aerosol scattering accounted for the most of extinction factors,andβsa varied seasonally from the peak in winter to the bottom in summer.The concentration of PM2.5 between 1 50 μg· m-3 and 200 μg·m-3 ,haze has the highest incidence,reaching 97.7%.The extinction factors of visibility is different as the diffierentof relative humidity and PM2.5 mass concentration.
