Abstract

The article considers the basic principles of structure formation in urboecosystems as conjugate active media. The mathematical model is based on the modified system of Fitz-Hugh-Nagumo equations. Criteria of formation of the transition zones between the cities were obtained from the aerial photographs of the cities near Moscow. The mathematical model and analysis of the real-world ecosystems have shown that non-regulated increase in the number and density of cities population leads not only to the increase of the cities areas, but, first of all, to the destruction of the natural subsystem due to the development in space and time of an autowave front of anthropogenic processes. The proposed approach makes possible to obtain an adequate estimation of an anthropogenic impact in excitable media of urboecosystems as conjugate natural and man-made structures and aims at identification of the threshold values of the control parameters in the processes of city formation.

Keywords
