Environmental Air Quality Change Trend Analysis And Prediction Research Of Shijiazhuang During The Period Of "11th Five-year Plan"

In recent years unceasingly developed along with the Shijiazhuang city socialeconomy,the urban environment contamination concern is day by day serious,the cityatmospheric environment pollution already became the people to prepare one ofenvironmental pollution questions which paid attention. Carries on the science to the cityatmospheric environment quality the appraisal as well as makes the effective forecast,hasvery important significance.In this paper, based on the environmental air quality during the period of "11thfive-year plan" Shijiazhuang city monitoring data.Union ambient air pollution exponentialmethod （API）, Ambient air synthesis pollution exponential method, In Shijiazhuang cityduring the period of "11th five-year plan" status and change trend of air environmentalquality made in-depth analysis. The analysis results show that, Three main pollutantconcentration change in volatility. City air pollution characteristics by" Coal ash"pollutionto the"compound "pollution". Ambient air pollution temporal variation trend is obvious,Pollutant concentration has obvious seasonal distribution, Heating time PM₁₀ and SO₂concentration is greater than the other time. Major pollutants in different space distributioncharacteristics of the obvious, SO₂and NO₂pollution levels higher than that of suburb,town and particulate matter pollution degree is slightly higher than the city suburbs.This article rests on the Shijiazhuang for2006-2012to be possible the PM₁₀,SO₂andNO₂three item of main air pollutant monitor data, Utilizes the grey system theory,Establishes GM（1,1） model.The air quality of the environment of urban area ofShijiazhuang "12th Five Year Plan" period is studied. The prediction results show,respirable particulate matter, sulfur dioxide, nitrogen dioxide concentration showed arising trend,but the respirable particulate matter, nitrogen dioxide concentration changetrend is not significant.According to Shijiazhuang “2006-2010” the year the ambient air quality condition,the union natural environment condition, the city space layout, the city industrial structure,the city energy structure, the city centralism heat, the city two times raise problem analysisair pollution and so on the dust primary causes.According to Shijiazhuang “2006-2010” the year period ambient air quality condition,the union natural environment condition, the city space layout, the city industrial structure,the city energy structure, the city centralism heat, the city two times raise problem analysis air pollution and so on the dust primary causes. Emergency measures of adverse weatherconditions, further optimize the industrial layout, Adjust the coal-fired power plants andcentralized computer layout, Strengthen industrial pollution prevention and control,control dust pollution.
