摘　　要：四川省大气背景站颗粒物PM2.5和PM10实时监测结果表明,两个点位的PM2.5浓度占PM10浓度分别为80.15%、68.9%,两个点位的PM2.5浓度和PM10浓度均呈显著线性关系,点位1:y=0.8634x-0.2212,R2=0.9823;点位2:y=0.7352x-0.2142,R2=0.7767。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）.
