中文摘要：

使用平面布点法对大气颗粒物进行监测，共采集了145个样品。系统分析了贵阳市市区各主要功能区（居民区、商业区、风景区、交通区）近地面大气颗粒物的TSP、PM10、PM2.5的浓度及其所含重金属量。结果表明：交通区PM10／PM2.5在各城市区域中污染最为严重，平均浓度值0．593mg／m^3、0．202mg／m^3，均高于国家《环境空气质量标准》二级标准，并且超标率为100％；一年四季中夏季污染浓度值最高，PM10／PM2.5的均值0．609mg／m^3、0．275mg／m^3，与气候干燥、风大有关；重金属元素中Pb和Zn的含量比较高，PM10／PM2．5中的含Pb为148mg／kg、274mg／kg，含Zn为344mg／kg、289mg／kg，这些重金属元素更易于富集在PM2.5细颗粒上，给环境带来了潜在危险。最后本文提出了贵阳城区PM10／PM2．5防治对策。

英文摘要：

According to a large number of environmental monitoring data by print distribution meth- od. a total of 145 samples, make systematic analysis of the functional urban area of Guiyang City （ resi- dential, commercial, scenic , traffic areas） near surface atmospheric particles TSP, PM10, PM2.5 con- centration and heavy metal . The results showed that： traffic district PM10/PM2.5 in various cities most polluted regions, the average value 0.593mg/m^3 and 0. 202mg/m^3 , were highter than the nation - Stand- ard of air quality , and exceeding - rate is 100% ; the highest pollution concentrations in the summer, PM10/PM2.5 mean 0. 609 mg/m^3 and 0. 275 mg/m^3 ; Pb and Zn content is higher in PM10/ PM2.5, the contain of Pb is 148 mg / kg and 274 mg / kg, the contain of Zn is 344 mg / kg and 289 mg/ kg, these elements more easily enriched in PM2.5 fine particles, a potential danger to the environment. Finally, Guiyang City PM10/PM2.5 proposed countermeasures, brought about a great potential danger, this paper write countermeasures Finally.
