The present paper describes the results of the research lixenobit, which is an indicator of the ecological zoning of urban territories (by the example of the city of Elista, Republic of Kalmykia). The basis of the study is selected route-stationary method. During the study in the city of Elista have been found 18 species of lichens, which were divided into three groups, dividing the territory of the city of Elista into three zones of contamination. When considering the distribution of lichens in general on the city’s territory there were a large number of lichen in the parks. Furthermore, it was noted the abundance of coverage trunks lichen in the summer planting and artificial forest plantations. Within the city there was impoverishment of lixenobited associated with the exhaust fumes of cars and atmospheric pollution. In process of removal from the center of the city species diversity of lichens are growing. Thus, the maximum number of species in lichen groups is typical for the forest zone in the vicinity of the city of Elista, where the overlap ecological niches sustainable, medium sensitive and sensitive to the pollution of species. Issues with the assessment of the impact of medico-geographical peculiarities of the study and the adjacent territories on human health were discussed. In particular, there were considered the issues of multifactor impact on human health. Identified areas of pollution mainly differ in the number of SO2. It should be noted is area of the smallest pollution (zone III) that outside of the city. lichens kind of Coloplaca on the highways on the concrete marked. Lichens type Xanthoria in the industrial zone, the Eastern part of the city, on the roofs and fences marked. But in the surroundings there were some instances of epiphytes lichens with necrotic spots. The growth of lichens is influenced by both natural and anthropogenic factors.
