中文摘要	利用乌鲁木齐2002年4月15日-2003年3月15日期间CE318太阳光度计的观测数据, 计算了气溶胶光学厚度, 对气溶胶光学厚度与地面污染物浓度之间的关系进行了探讨.乌鲁木齐的首要污染物为PM_(10), 其次是SO_2.结果表明, 全年中乌鲁木齐气溶胶光学厚度与PM_(10)、 SO_2浓度的逐月变化趋势基本一致.气溶胶光学厚度与PM_(10)浓度日均值、月均值的相关系数分别为0.4104和 0.5922, 与SO_2浓度日均值、月均值相关系数分别为0.3212和0.8168.每月SO2浓度和硫酸盐化速率的相关性很高, 为0.8430, 所以导致SO_2对气溶胶光学厚度的贡献更显著.这在一定程度上说明SO_2浓度是估测气溶胶光学厚度的一个较好参量.
英文摘要	urumqi city,located in northwestern semi-arid area of China,is well known for its serious air pollution.In this article,aerosol optical depth(AOD) was retrieved from observation measured by sun photometer CE318 from April on 15 2002 to March on 15 2003.There were two principal kinds of air pollutants in rumqi,namely PM_(10) and SO_2.Combining AOD and air pollutant concentration such as PM_(10) and SO_2,the relationship between these elements was discussed.The research results showed that the monthly mean AOD changed in the way consistent with pollutant concentration changing year around.The correlation coefficients between AOD and daily and monthly means of PM_(10) were 0.4227 and 0.5993,respectively;correspondingly,that ones between AOD and SO_2 were 0.3212 and 0.8168,respectively.The correlation coefficient between monthly mean concentration of SO_2 and monthly mean sulfation rate was very high with the value of 0.8430,which means concentration of SO_2 made great contribution to AOD.It was possible for concentration of SO_2 to evaluate AOD to a certain extent.
