摘要
为推动唐山市空气质量改善,以PM2.5、PM10、CO、NO_(2)、O_(3)、SO_(2)六项大气污染物数据为基础,通过相关性分析和因子分析,探讨了影响唐山市空气质量变化的成因。结果表明:不同污染物的相关性研究结果显示,影响唐山市空气质量的主要污染物是SO_(2)、CO、PM2.5和PM10,其次是O_(3)和NO_(2);从空间上看,中部地区相较沿海地区、迁西县和迁安市污染较为严重;唐山市以第二产业为主的特征导致煤炭消耗量高、企业排放量大、柴油货车多,是导致唐山市空气质量不佳的主要原因。
In order to promote the improvement of air quality in Tangshan,based on the six air pollutant data of PM2.5,PM10,CO,NO_(2),O_(3) and SO_(2),through correlation analysis and factor analysis,the causes affecting the change of air quality in Tangshan are discussed.The results showed that:The correlation study of diff erent pollutants showed that the main pollutants aff ecting air quality in Tangshan were SO_(2),CO,PM2.5 and PM10,followed by O_(3) and NO_(2);In terms of space,the central region is more polluted than coastal areas,Qianxi County and Qian’an City;Tangshan’s secondary industry led to high coal consumption,large enterprise emissions,and many diesel trucks,which are the main reasons for poor air quality in Tangshan.
