Zusammenfassung:This paper is about the analysis on the characteristics and parameters of particle size of atmospheric dust in the spring of Xianyang city, in order to understand their potential sources and the impacts on the environment. The results show that the size of dust particle mainly concentrated in 4-32 ¿m; the average PM10 account for 35.1% of all the dust, PM2.5 account for 9.9 %. It shows that the pollution of atmospheric particle is heavy, particularly in the business district; on the other hand, human activities such as the burning of motor vehicles, production and daily life have greater impact on the atmosphere in Xianyang city. The source of dust on the whole is natural, but the impact of human activity is obvious on PM2.5 and the particles which size >50 ¿ m.
