Analysis on Atmospheric Environmental Quality Variation and Countermeasures in Urban Area of Nantong City

Based on the data obtained from years of monitoring,this paper analyzes changes in atmospheric pollution factors（SO2,NO2,PM10）in recent years in the urban area of Nantong city and founds that SO2 pollution ameliorates,NO2 content meets the standards,PM10 pollution close to national air quality standards and urban air pollution classification is in the level of light pollution.This paper also studies and discusses the influences and causes for the variation of atmospheric environmental quality,then puts forward countermeasures for comprehensive control and manage,expecting to provide worthy basis and theories to economic development and better environment of Nantong City.
