摘要
2012年入冬以来,郑州市与我国中东部地区一样出现大范围长时间雾霾天气,其中主要成分是PM2.5.PM2.5污染成为影响郑州市空气质量的首要问题.根据监测结果分析郑州市冬季PM2.5污染时空分布特征,并与气象因素进行相关性分析,郑州市PM2.5在污染物排放相对稳定前提下,受气象因素影响较大,特别是冬季更为明显.
Since the winter of 2012, haze in a wide range of Zhengzhou has been occurred for a long time as well as China＇s central and eastern regions. The main source of haze is PM2.5, which has been the most important root that affects Zhengzhou＇s air quality. Based on the monitoring results of Zhengzhou＇s PM2.5 pollution in winter, its spatial and temporal distribution characteristics and the correlation with meteorological factors has been analyzed. The result showed that the PM2.5 pollution in Zhengzhou is greatly influenced by meteorological factors under a constant pollution emissions, especially in winter.
