Abstract. The paper shows that the fulfillment of construction works influences the level of fine dust content in urban environment. Investigations of fine dust emissions in the zones of earth excavations and soil spoil banks caused by construction works were carried out. The authors conducted an integrated investigation of the physicochemical processes in the surface layer of the atmosphere in the course of construction works, which was based on the field and computational experiments. With the help of a laboratory wind-tunnel plant, it was revealed that the character of dust emission during the development of dispersive massifs depends on the climatic conditions, in particular on the wind velocity and the physical-and-mechanical properties of the rocks (humidity, porosity, plasticity indices). A specific-purpose GIS application has been designed which allows modelling the dynamics of air flows in the territories with anthropogenic development. The application is based on the methods of mathematical and simulation modelling, the methods of visualization and surface plotting as well as the methods of software applications development.
Key words: dust emission, atmospheric pollutants, soil massif, geo-information technologies, modelling packages.
