%X Based on the data acquired from PRD(Pearl River Delta) observation campaign from October 1 to November 5, 2004, analyzing the relationship among atmospheric visibility in Guangzhou and gaseous pollutant, aerosol mass and chemical component. Extinction proportion of each factor is given: b_ sa 75.26%,b_ aa 12.89%,b_ sw 5.78%,b_ ag 3.68%,b_ sg 2.38% respectively. Contribution of different particles to scattering is analyzed. Lastly, experiential function among b_ sa and PM2.5 concentration,PM10 concentration and chemical components is obtained based on the method of stepwise multiple linear regression, then,the mass scattering coefficient is put forward.
