摘　　要：根据2014年1月1日-6月30日江苏省13地级市监测PM2.5,PM10的数据,分析其污染特征。结果表明：全省PM2.5和PM10污染较严重,全省PM2.5,PM10超标率都分别达到78.33%,66.11%以上,尤其是细颗粒物的污染占主导地位;PM2.5/PM10的比值范围达到0.461 9~0.687 2,全省PM2.5和PM10之间存在显著的线性关系;PM2.5,PM10浓度时空分布特征为PM2.5：1月〉3月〉2月〉5月〉6月〉4月,PM10：1月〉5月〉3月〉6月〉2月〉4月;苏北〉苏中〉苏南。The paper analyzed the pollution characteristics according to the PM2. 5and PM10 monitoring data of Jiangsu Province from January 1st to June 30 th,2014. The results showed that pollution of PM2. 5and PM10 in the whole province is serious and exceeded 78. 33% and 66. 11%,respectively,especially fine particulate matter pollution is dominant. The ratio of PM2. 5and PM10 range from 0. 461 9 to 0. 687 2,there is a significant linear relationship between PM2. 5and PM10. The provincial PM2. 5and PM10 concentration of space- time distribution features of Jan Mar Feb May Jun Apr; Jan May Mar Jun Feb Apr; Southern Jiangsu Central Jiangsu Northern Jiangsu,respectively.
