| In recent years,a large area of Hebei Province has frequent smog and frequent worsening of regional air pollution with particulate matter as the main pollutant,which is constantly threatening the health of the people.On the other hand,the issue of regional and complex air pollution poses a huge challenge to the coordinated and sustainable development of our economy,society and the environment.In this paper,the prominent problems of air pollution in Hebei Province are studied.The meteorological data and atmospheric environmental monitoring data of three typical cities of Shijiazhuang,Baoding and Xingtai are collected and analyzed.Combined with the evaluation model of air quality index,the basic urban pollutants,Including PM2.5 and PM10 particulate matter,sulfur dioxide,nitrogen oxides and ozone and other major pollutants were studied,a comprehensive analysis of the typical city of Hebei Province,the characteristics of atmospheric pollution.Through the analysis of the 2015 air pollution status and pollution characteristics of Shijiazhuang,Baoding,Xingtai three cities show: In terms of air quality,the monthly changes of AQI in the three cities are more obvious,showing a "U-shaped" trend.Summer AQI generally lower,better air quality,winter AQI generally higher,more serious air pollution.Shijiazhuang,Baoding,Xingtai particulate matter concentration exceeded the standard overall,the three cities in contrast,Baoding City and Xingtai City,the air quality status can not be optimistic.As a result,the status quo of air pollution in the three cities is the result of a combination of natural and human factors.In addition to the natural factors,the three typical cities are developed industrially,the economy is developing rapidly,and at the same time,there are ubiquitous situations such as dense population,heavy traffic flow,unreasonable energy structure,single industrial structure and low urban greening rate.Resulting in more serious air pollution in our province. |
