The method of calculating the fractal dimension of dirt surface fields, based on studying the dependence of the pollutant mass and the occupied area formed in double logarithmic coordinates at concentrations above the specified level is introduced. The fractal dimension value of the surface pollution fields dependence on the number and mutual arrangement of sources has been researched. The fields of pollution have been calculated by a cellular automata simulation model for 1,2,2,4-point sources of equal emission power which had been located close to and far away from each other, wind velocity = 0. The criterion for distance between sources is the full width at a half maximum (FWHM) R of single-source pollution spread. The field model size is 2x2 km, the atmosphere height is 1 km. The fractal dimension value (from Df = 1,88±0,01 to 1,591±0,003) decreases with the source number increase only when they are close to each other (the distance between the sources centers is on the order of 1,2 R).
