| 摘要: |
| 根据2010年6月1日至2011年5月31日南宁市的环境监测数据和气象数据,分析南宁市灰霾天气特征,然后通过SPSS软件分析灰霾天气与能见度、颗粒物(PM2.5、PM10)浓度、气态污染物浓度和空气污染指数的关系,探讨南宁市灰霾天气与空气污染物的关系。结果发现,南宁市灰霾天气主要分布在秋、冬两季,PM2.5是直接造成南宁市灰霾天气的主要因子,PM10、SO2、NO2、CO和O3对灰霾天气的发生也有一定影响。PM2.5与PM10相关性最显著,与SO2、NO2相关性较显著,与CO相关性显著,与O3相关性不显著。 |

| Abstract: |
| Based on the analysis of the environmental monitoring and meteorological data in Nanning from June to May,2011,the paper studied the characteristic of haze in Nanning. Then by SPSS software, the relationship between haze and visibility, the concentration of particulates (PM2.5, PM10), the concentration of gaseous pollutant, air pollution index was analyzed. The results indicated that haze mainly appeared in autumn and winter. PM2.5 was the major factor caused haze in Nanning,PM10,SO2,NO2,CO and O3 also affected the haze in certain degree. The correlation of PM2.5 and other pollutants such as PM10,SO2,NO2,CO was very significant. However, no significant correlation of PM2.5 and O3 was obtained. |
