Vegetation cover, which reflects all the trends in the urban area, is the main component of urbogeosystems. As vegetation is possible to determine the quality of the urban landscape. In this connection, an attempt to trace the urbogenezis dynamics for example of a large industrial center and to estimate whether the city growth rates reflected in the rates of its planting greenery. In the article results of an assessment of dynamics of the area of housing and industrial estate in the Volzhsky city are presented. Research of urbanized area were conducted using Landsat space images for different years. Consecutive drawing up "compute difference map" for a series of couples of space images of 1950-1980, 1980-1990 and 1990-2000 years allowed to receive quantitative characteristics of a trend of growth of building in Volzhsky. The digital map of spatial dynamics of an urban area which analysis allowed establishing the main tendencies in development of processes of an urbogenesis within Volzhsky is made. The squares of the city given about growth Volzhsky are compared to data of population and the area of green plantings for the same period. It marked slowdown in the growth of the city in breadth, since 1995, compared with the beginning of the 1980. The consequence of the spatial urban sprawl outwards becomes a transformation of urban ecosystems, which is to reduce the amount of greenery in the direction from the central part of the city to its suburbs.
