| 利用统计学和GIS方法对2016年武汉市各区不同污染物的时空分布特征及相关性进行分析。结果表明：武汉市大气污染季节性特征明显，春季和冬季颗粒物（PM2.5、PM10）及NO2污染突出,夏季O3污染严重。污染物空间差异显著，主城区和东西湖区颗粒物及NO2污染严重，郊区O3污染严重。平均气温、平均水汽压与SO2、NO2、CO、PM2.5和PM10均呈显著负相关，而与O3呈显著正相关；降水量与SO2、NO2和CO呈显著负相关。 |

| The spatio temporal distribution characteristics of air pollutants and the correlation between them in each district of Wuhan in 2016 were analyzed by statistical method and GIS. The results showed that the seasonal characteristics of air pollution in Wuhan were obvious, and the pollution of particulate matter (PM2.5, PM10) and NO2 in spring and winter were prominent. The pollution of O3 in summer was serious. The spatial distribution of pollutants varied significantly. The particulate matter and NO2 in the main urban area and Dongxihu District, and O3 in the suburbs were serious. The average air temperature and vapor pressure had significant negative correlation with SO2, NO2, CO, PM2.5, PM10, and a significant positive correlation with O3. The precipitation had significant negative correlation with SO2, NO2 and CO. |
