摘　　要：亚运期间利用多轴差分吸收光谱仪(MAX-DOAS)对广州市的大气污染物进行了实时监测,分别对重要大气常规污染物NO_2和SO_2的日变化特征进行了探讨和分析,并通过结合气象条件和周围的重要污染源综合监测结果分析研究了广州市周围的区域污染输送,结果发现位于市东南部的工业区对于市区的污染存在较大的影响,其中以SO_2尤为明显。分析NO_2廓线结果表明,污染物主要位于1 km以下,高污染层主要位于0.5 km以下。During the Sixteenth Guangzhow Asian Games multi-axis differential absorption spectrometers （MAX-DOAS）were used to monitor the atmospheric pollutants real-time in Guangzhou.As the atmospheric conventional and important pollutants,the daily change characteristics of SO_2 and NO_2 are discussed and further analyzed respectively.By combining meteorological conditions and the important pollution sources around Guangzhou the comprehensive regional pollution transport is analyzed.And it shows that the industrial area located in southeast of Guangzhou plays an important role in the pollution transport,among which SO_2 is especially remarkable.The analysis of NO_2 profile results shows that the pollutants mainly located in 1km below,and the high pollution layer mainly located in 0.5 km below.
