Keywords: Air pollutants; Correlation analysis; Nanchang.
The air quality have drawn high attention by public due to it special location and the development strategy. 1.
Resource Air pollutants SO2, NO2 andPM10 measurement methods includes: Determination of SO2: Formaldehyde absorption - Pararosaniline spectrophotometry (GB/T 15262-94) Determination of SO2: Formaldehyde absorption - Pararosaniline spectrophotometry (HJ 482-2009) (To substitute GB/T 15262-94 from Nov. 1, 2009) Determination of NO2 : Saltzman (GB/T15436-1995) Determination of NO2: Naphthyl ethylene diamine dihydrochloride spectrophotometric method (HJ 479-2009, To substitute GB/T 15436-1995 from Nov. 1, 2009) Determination of PM10: Determination of the concentration of airborne particulate (HJ 618-2011) (To substitute GB6921-1986 from 2011) According to the monitoring data, the concentration of air pollutants sulfur dioxide, nitrogen dioxide, PM10 10 year (2003-2012) annual statistical data, and reference to the research results of many scholars from 2003 [1], can be pushed forward to 1996, which won the concentration variation of 1996-2012 for up to 17 years of three kinds of
main pollutants, drawing the air pollution interannual variation trend of Nanchang City as shown in Figure 1, the time span, more easy to explain variation.

Industrial pollution sources were the main causes of dust haze pollution, some scholars pointed out that Hebei province was in the middle of industrialization development stage [1], relatively backward industrialization process determines the Hebei in the integration construction must make adjustments.
So we must scientific evaluation of power industry dust haze that make a balance of social development and dust haze reduce. 1.
