Analysis on Gray Relation of Affected Factors of Atmospheric NO_x Concentration in Guangzhou
Xu Jiaying Yang Shihong South China Normal University, Guangzhou 510631
Several affected factors of atmospheric NOx concentration have been analyzed by applying theory and relation method of grey-system. The result showed that the hourly average vehicle flow and the area of motor road in Guangzhou proper were two major factors which affected atmospheric NOx concentration. Adopting grey model GM (1,1) to forecast the variation of NOx concentration, and relevant countermeasures to control and eliminate NOx pollution were put forward.
