摘　　要：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(PM_(2.5)、PM_(10))及NO_2污染突出,夏季O_3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NO_2污染严重,郊区O_3污染严重。平均气温、平均水汽压与SO_2、NO_2、CO、PM_(2.5和PM_(10)均呈显著负相关,而与O_3呈显著正相关;降水量与SO_2、NO_2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 in2016were analyzed by statistical method andThe results showed that the sea-sonal characteristics of air pollution in Wuhan were obvious,and the pollution of particulate matter(PM25,PM10)and NO2in spring and winter were prominent.The pollution of O3in summer was serious.The spatial dis-tribution of pollutants varied significantly.The particulate matter and NO2in the main urban area and Dongxihu District,and O3in the suburbs were serious.The average air temperature and vapor pressure had signifiCant neg-ative correlation with SO2,NO2,CO,PM25,PM10,and a significant positive correlation with O3.The precipita-tion had signifiCant negative correlation with SO2,NO2and CO.
