以冷空气过境前后的广州市污染物数据为基础，运用 Shapiro-Wilk 检验、Pearson 积矩和 Spearman 秩等方法，探讨 PM2.5、PM10、SO2、NO2、O3、CO 的污染特征及变化规律.结果表明，PM2.5、PM10高浓度出现在8-9时和17-18时，低浓度出现在12-13时和0-1时. PM2.5和 PM10相关性显著，PM2.5/ PM10=0.62~0.83，冷空气对 PM2.5和 PM10都有较好的清除作用. SO2浓度在7-8时出现峰值，3时出现谷值，良好的气象条件对 SO2有明显的清除作用. NO2、CO 高浓度出现在9时和19时，低浓度出现在15时和3时.冷空气对NO2有一定的清除作用，对于 CO 浓度增大的异常情况，推断与广州以北地区燃烧生物质有关. O3浓度日变化呈现单峰特征，15时浓度最高，5时浓度最低，冷空气在夜间过境对O3浓度影响较小. O3与 CO、NO2存在显著的负相关，在光化学反应时间段 O3/ CO =0.06~0.12，O3/ NO2=1~2.

According to the concentrations of Guangzhou atmospheric pollutants before and after a cold air transit, the polluted characteristics and variation of PM2. 5 ,PM10 ,SO2 ,NO2 ,O3 ,CO are studied using Shapiro-Wilk Test, Pearson correlation and Spearman correlation. It is found that the highest concentrations of PM2. 5 and PM10 appear at 8:00 - 9:00 and 17:00 - 18:00,while the lowest of those shows at 12:00 - 13:00 and 0:00 - 1:00. The corre-lation between PM2. 5 and PM10 is significant,and the value of PM2. 5 / PM10 is at the range of 0. 62 - 0. 83. Cold air transit can clear up PM2. 5 and PM10 significantly. The highest concentration of SO2 appears at 7:00 - 8:00 while lowest shows at 3:00. Meteorological condition plays a significant role in the clearance of SO2 . The high concentra-tions of NO2 and CO appear at 9:00 and 19:00 while lowest of those shows at 15:00 and 3:00. After the transit of cold air,concentrations of NO2 reduces while CO increases. It is inferred that biomass burning in the north of Guangzhou is attributed to the abnormal increase of CO concentration during the transit of cold air. The concentra-tions of O3 show a very clear cycle with one peak at 15:00 and a trough at 5:00. When the cold air comes,concen-tration curve of O3 shows little decline. The correlations between CO,NO2 and O3 are significantly negative. During the period of photochemical reaction,the value of O3 / CO is at the range of 0. 06 - 0. 12 and the value of O3 / NO2 ranged from 1 to 2.
