| 摘 要： | 为了降低天津市滨海新区中PM_(2.5)的污染,需要对天津市滨海新区PM_(2.5)污染的时空分布和影响因素进行研究。研究天津市滨海新区近年来PM_(2.5)的时空分布特征,并选取PM_(2.5)的相关指标,对天津市滨海新区PM_(2.5)污染影响因素进行分析。结果表明,在天津市滨海新区的冬季时,PM_(2.5)的质量浓度值最高,在滨海新区的夏季时,PM_(2.5)的质量浓度值最低。PM_(2.5)在天津市滨海新区昼间大气中的质量浓度低于夜间大气中的质量浓度。

| Abstract: | In order to reduce the pollution of PM2.5in Tianjin Binhai New area, this paper studied the spatial and temporal distribution and influencing factors of PM2.5pollution in the region in recent years. The influencing factors of PM2.5in Binhai New area of Tianjin were analyzed by selecting the relevant indexes of PM2.5.The results showed that the mass concentration of PM2.5in Tianjin Binhai New area was the highest in winter. The lowest mass concentration of PM2.5in summer. The diurnal atmospheric mass concentration of PM2.5in Binhai New area of Tianjin is lower than that in night. |
