Annotation:  This paper studies the territory of a nature reserve within the boundaries of the modern megalopolis (Moscow) by applying the landscape profiling method. Landscape profile was laid with the use of landscape Catena. Landscape Catena is formed by consecutively changing aquatic systems and it is based on location within the Catena, the individual elements or units. The method of landscape Catena establishes a functionally dynamic relationship between the individual elements of the internal structure of the landscape. It is established that the ecological situation is alarming in 40% of the territory of the nature reserve predominantly in the cultural and roadside functional zones (high levels of industrial and phytopathogenic microorganisms, a strong alkalization of the topsoil pH of 7.5; a large number of microorganisms to 270×105 cells/g with a predominance of bacteria from the phylum Firmicutes). The natural objects on the territory of the natural reserve area “The Valley of The Setun River” have a year-round negative impact such as dust and gas emissions on the transport infrastructure of the city.
