| Abstract: | The monthly variation and annual variation of descend dust in Lanzhou city was investigated, respectively Progressive regression analysis was used to screen variables By using principal component analysis, the principal components of descend dust pattern clearly In addition, a novel multiple self regression prediction equation was set up and successfully used to predict the descend dust of the city proper Compared to the practical measurement, satisfied results were achieved |
