The article presents some aspects of the problem of isolation and mapping of urban ecotones. The study of transition zones is necessary not only to determine the boundaries of natural and man-made systems, but also to determine the internal structure and mechanisms of functioning of ecotones. One of the main difficulties mapping ehkotonnyh bands, is the lack of a common classification in step significantly complicates mapping.
