根据郑州市2013年PM2．5和PM10颗粒物连续自动监测数据，对郑州市各国控站点的PM2．5和PM10的达标情况、变化趋势等进行探讨分析。结果表明：2013年郑州市PM10和PM2．5的年均质量浓度均超过了新标准规定的年均值二级标准限值。 PM10和PM2．5月均值峰值出现在1月和10月，谷值出现在8月，各月PM2．5的超标天数都大于PM10。PM10和PM2．5冬季的日均值浓度明显高于其他季节，呈双峰型，夜晚浓度整体高于白天；PM2．5春、夏、秋三季日变化呈单峰型，PM10夏季和秋季呈单峰型，春季呈双峰型。 PM2．5和PM10日均值有着非常显著的线性相关关系，PM2．5和PM10浓度的比值（p）10月最高。

This paper analyzed reach the standard and variation trend of PM 2.5 and PM10 from Zhengzhou national control sites according to continuous automatic monitoring data in 2013 .The results show that the annual average mass concentrations of PM2.5 and PM10 in Zhengzhou in 2013 exceeded annual average standard of grade secondary standard limit in the new criterion . The results also shows that PM 10 and PM2.5 monthly mean peaks appeared in January and October and troughs in August , and the number of days of PM 2.5 exceeding the standard was larger than that of PM 10 in each month.The daily average concentra-tions of PM10 and PM2.5 in winter were significantly higher than that in other three seasons during 2013 and presented as bi-modal distribution , meanwhile their concentrations during nights were integrally higher than that during days .The diurnal vari-ation of PM2.5 in spring, summer and autumn were single peak type .The diurnal variation of PM 10 in summer and autumn were single peak type and bimodal distribution in spring .There was a significant linear relationship between PM 2.5 daily mean con-centration and that of PM10, at the same time the ratio(p) of PM2.5 and PM10 concentration was the highest in October .
