In this study, a graphic representation method and a hierarchical mining analysis scheme was proposed based on the effect of meteorological factors on PM_(2.5). The characteristics on the PM_(2.5) pollution change and influenced by meteorological factors in Beijing have been obtained. An experiment for high PM_(2.5) pollution process prediction have conducted based on the knowledge obtained by mining analysis. The high PM_(2.5) pollution phenomenon can be captured accurately by the prediction of PM_(2.5) pollution based on mining association knowledge. The hierarchical analysis scheme on mining PM_(2.5) pollution still exist shortages, and need further study in the future.
