摘　　要：在徐州市的7个典型城市功能区采集大气颗粒物样品,对PM_(10)和PM_(2.5)的污染水平进行了分析。结果表明,徐州市PM_(10)和PM_(2.5)的污染较严重,超标率分别为26.3%和31.2%;空间上,工业区和交通居住混合区污染严重;时间上,污染水平呈现为冬季>春季>秋季>夏季;PM_(2.5)在PM_(10)中的比重大于粗颗粒物,约占58%,应重视对其监测与治理。For investigation of pollution levels of airborne particulate matter in Xuzhou City, airborne particulate PM10 and PM2.5 samples were collected at seven typical functional areas of Xuzhou City. The results showed that the pollution by PM10 and PM2.5 is serious. The rates exceeding the standards are 26.3 % and 31.2 % for PM10 and PM2.5 respectively. In space, the industrial zone and the mixed area of the transportation and residential pollution are more serious than others; in time, the pollution level is presented as the winter〉spring〉autumn〉summer. The PM2.5 fraction accounts approximately 58% of the PM10.
