Abstract:

In order to study the quality of atmospheric environment change in recent years in tangshan, understanding the atmospheric pollution of the environment factor, selecting SO2, NO2 and PM10 as evaluation factors, consulting the standards relevant to atmospheric environment and calculating the weight, distribution coefficients of weight, grade attachment of atmospheric pollution factor. The results of weight analysis indicated that the main pollution factor is PM10 in 2004 and SO2 in2005-2010. The results of comprehensive evaluation showed that atmospheric environment of Tangshan was mildly polluted (Grade Ⅱ), and it has been improved year after year.
