| Abstract: | The air environmental background value monitoring results of PM,0 and PM2.5 in Sichuan province showed that the ratio of PM2.5 to PMl0 in the two monitoring site were 80. 15%, 68.9% respectively. The PM2.5 and PM10 w at both monitoring sites showed significant linear relationship. The linear regressive relation of one site is y = 0. 8634x-0. 2212 （R^2 =0. 9823）, the other site is y =0. 7352x -0. 2142 （R^2 =0. 7767）. |
