Structural-dynamical analysis of the state of the biota of soils in urbanized geosystems (Exemplified by the City of Sayanogorsk)

摘要

We report the results from investigating the ecological state of the urbanized geosystems in the city of Sayanogorsk. A comparative analysis is made of the structure of zoocenoses against the natural and anthropogenically disturbed soils predominating in the region. We examine the transformation conditions for soil cover and the ecologically important factors influencing the state of soil-biotic communities. The study revealed a negative influence of urban pressure on the population and biomass of invertebrate animals and demonstrated the possibilities of using the structure and quantitative characteristics of zoocenoses in biodiagnostics of changes of steppe geosystems under the influence of anthropogenic factors.
