%X Based on the approximation classification thoughts and method of rough sets theory for uncertainty information,calculation were carried out to study the classification relation betwwen the different extents of element components of atmospheric pollution sources and the element contents of atmospheric particulate samples.Importance evaluation of source was performed using the effective extent of source as standard for the element content of atmospheric particulate.Analyses of cases and comparisons with other source apportionments suggested that the orders of importance of main atmospheric pollutant sources show no difference using different sources apportionment.
