摘　　要：指出了冬季是郑州市区霾天气高发季节,环境空气中PM_(2.5)质量浓度在郑州市各城区的差异和影响因素尚需进一步讨论。采用全国城市空气质量实时发布平台于2015年11月18日至2016年1月31日期间发布的郑州市五城区监测点的PM_(2.5)质量浓度数据和郑州市经济统计数据,分析了各城区间PM_(2.5)污染水平的特征、相互关系及影响因素。结果显示:霾高发季节郑州市各城区之间的PM_(2.5)质量浓度相关性显著,各城区的经济结构对PM_(2.5)污染水平的影响也比较显著,城市的绿色发展对区域PM_(2.5)污染水平具有积极作用。Zhengzhou had a high frequency of haze in winter. There are some questions on the differences of aerosol PM2.5 mass concentration among the districts of Zhengzhou and the influencing factors on those differences. This study collected PM2.5 mass concentration data during Nov. 18, 2015 to Jan. 31, 2016 and economy statistic data from 2015 to 2016 of five districts in Zhengzhou. PM2.5 pollution characteristics and interrelation of those districts and their influencing factors were analyzed based on Pearson＇s correlation analysis and other methods. The results showed that the correlations between PM2.5 mass concentration data of all districts were significant in the haze season. Economic development contributed to high PM2.5 mass concentrations for all districts. Hence, green--development might pro duce positive effects to reduce PM2.5 pollution in city developing process.
