Application of Rough Sets Theory to Sources Analysis of Atmospheric Particulates

In this paper, the rough sets theory (RS) is used to analyze the pollution sources of the atmospheric particulates in heating period and non-heating period of Jilin City. The result shows that the sorting results of pollution sources of atmospheric particulates in Jilin City which are calculated by the rough sets theory and CMB model are similar. In heating period, the greatest contribution to atmospheric particulates of Jilin City is fugitive dust, while in non-heating period the most contributing pollution source is construction dust. Rough sets theory on sources analysis of atmospheric particulates is simple, practical, and less demanding on the data. It is especially proper to be applied in the small and medium cities.
