贵州省主要城市PM10污染特征分析

对贵州省主要城市（贵阳、毕节、遵义、都匀、安顺、盘县）10个采样点的PM10按季节进行了系统采样,分析了其时空污染特征。结果表明：从季节分布上看,盘县、安顺和毕节春夏季PM10污染较严重,其他采样点冬季污染较重;从空间分布上看,毕节、遵义污染较严重,毕节市区点PM10平均浓度为（206.8±42.6）μg/m^3;贵阳污染较轻,市区点PM10平均浓度为（113.3±26.9）μg/m^3;参考环境保护部发布的2012年中国环境状况公报中的空气质量状况,并与郑州市、呼和浩特市、北京市、海口市近几年PM10污染水平相比较,2012年贵州省主要城市PM10污染不严重,空气质量在全国城市中较好。

Pollution Characteristics of PM10 in Main Cities,Guizhou Province

PM10samples of 10 locations were seasonally collected in main cities（such as Guiyang,Bijie,Zunyi,Duyun,Anshun,Panxian etc）from March,2012 to February,2013,and its temporal and spatial distribution characteristics were analyzed.The results show that for seasonal distribution,concentrations of PM10 samples collected in spring and summer were higher in Pan county,Anshun and Bijie city,otherwise,those in winter were higher;for spatial distribution,the concentrations of PM10 of Bijie and Anshun city were higher,with the average concentration of PM10 at urban site of Bijie reaching to（206.8±42.6）μg/m^3,however,that of Guiyang city was lowest,with the average concentration of PM10being（113.3±26.9）μg/m^3.Referred to air quality status of Bulletin Chinese environment in 2012 issued by Ministry of Environmental Protection and compared with Zhengzhou,Hohhot,Beijing and Haikou City,PM10 pollution of main cities in Guizhou province is not serious,and the air quality is better in 2012.
