Abstract
The article discusses the main methods of assessing the environmental balance of the urbanized territory of a model area of the city of Irkutsk through a system of quantitative assessments and expert verbal descriptions of the studied processes based on geostatistical data. An inventory was carried out and a database of spatial and non-spatial data was compiled on the basis of cadastral division of the territory; types of land use and functional types of the site development were identified; the engineering and transport infrastructure, the location of industrial enterprises, recreation areas and public improvements were assessed. Functional types of the category with different degrees of anthropogenic impact and socio-ecological significance have been identified: influencing, neutral, and environment-forming, as well as local areas of environmental stability. Spatial data is represented as a vector topological model of data, surfaces and isolines, attribute data is represented as a set of MapInfo tables, with which it is easy to perform restructuring operations – changing the structure and composition of data tables and structured queries.
