ENVIRONMENTAL MONITORING OF URBAN SOILS USING MODERN GIS TECHNOLOGIES (ON THE EXAMPLE OF SARATOV-ENGELS AGGLOMERATION)
Currently, environmental pollution is a rather acute and urgent problem. At this time, changes in the composition of microbial complexes and the biochemical activity of the soil cover of urban landscapes have been investigated. The change of the main ecological and physiological groups of microorganisms in selected soil samples of the city of Saratov and the city of Engels is shown. In the study of enzymatic activity, a low content of all enzyme groups and respiratory activity of urban soils in various functional zones of the studied agglomeration was revealed. According to the results of the research, maps of the ecological state of urban technogenically polluted landscapes were constructed.
