The study addressed the issue of biological monitoring of the functional state of different types of urban soils of Astrakhan. Studied urbanozem, URBO-soils, culturosity and natural soils are located in different administrative districts of the city and affect how socially important facilities (yard and playgrounds, areas teaching hospitals), and little converted ecozone (recreation areas and leisure). Studied indicators of urban ecosystems: biochemical and microbiological. Was used to determine the enzymatic activity of the studied soils on the determination of oxidoreductase is a catalase and hydrolase is invertase, urease standard methods. The number of bacteria, actinomycetes and micromycetes were determined using the method of fluorescent microscopy; the number of ecological-trophic groups of microorganisms (ammonifying, amylolytic, spore forming bacteria) was determined using the method of inoculation medium. For the evaluation of biological activity and ecological-biological condition of urban soils of Astrakhan used the integral indicator of ecological and biological condition of soil (IIEBCS).
