Research On The Time-space Distribution Of SO₂ During The Period Of Smog In Beijing-Tianjin-Hebei Region,2015

With the rapid economic development,industrialization and urbanization speed up,environmental governance in China is facing a serious problem that the regional atmospheric environmental problems.In recent years,haze weather happened frequently in Beijing-Tianjin-Hebei region,SO₂ pollution is serious,cause the extensive concern of the whole society.Understand the area SO₂ space-time distribution change law research on atmospheric environment and air quality control has important significance.Based on the atmospheric probe of carrying on the Aura of ozone watcher OMI?Ozone Monitoring Instrument?of SO₂ sensor data products as the basis,combined with remote sensing image processing technology and geographic information system analysis method,to study the Beijing-Tianjin-Hebei region space-time distribution of the atmospheric boundary layer SO₂in 2015.Combined with the region gray haze weather process,analysis of SO₂ during this time and space changes.Significant influence on human activities during the Spring Festival,the parade of air quality change are studied,and analyzes the strong fog haze pollution in the process of climate factors.In this paper,the main conclusions are:?1?of SO₂ column value with high spatial distribution of the main areas in southern Hebei province,Shijiazhuang,Handan,Xingtai,Tangshan area,low overall assumes the meteorological north.?2?continuous ash haze weather change rule in the process of SO₂ is increased before they are reduced.?3?human activities have important influence on atmospheric environment quality.Regional cooperative governance is an important means of controlling air quality in Beijing-Tianjin-Hebei region.Strong fog haze pollution shows that wind speed is small,climate impact factors in the process of inversion is strong,the weather is in static stability condition,not conducive to the spread of SO₂,pollution process lasts longer,strength larger.
