The classification of intense geoecological situations and their landscape conditionality (by the example of the Volgograd region)

Currently, the geoecological situation is the main structural unit in the comprehensive study of modern problems of nature management and the main subject of environmental mapping at any spatial level. Each geoecological situation is formed within a specific geosystem and depends on its properties, structure, dynamics, functioning, it also has specific time characteristics. The methodological basis is the geosystem concept, the doctrine of modern landscapes as natural-anthropogenic geosystems. The classification of geoecological situations is carried out by a set of signs, by a set of problems, by the type of anthropogenic impacts and their depth, by leading factors of formation, by the scale of manifestation, by the time of existence, etc. The determination of the severityof the geoecological situation depends on the regional characteristics and specifics of the leading problems and can be considered separately or from the point of view of the living conditions of the population and its state of health or from the point of view of the state of natural resources, geographical components, the preservation of natural geosystems, the uniqueness of landscapes and the gene pool of living organisms. When determining the severity of the environmental situation, an ecocentric (geocentric) integrated approach was used. It allows you to objectively assess the situation in terms of the state and degree of change in geosystems. As a result of the research, it was established that about 63 % of the territory of the Volgograd region is characterized by a conflict and tense geoecological situation. A satisfactory geoecological situation is observed in western areas characterized by the best bioclimatic indicators, the lowest population density, and the level of anthropogenic load. A tense and critical geoecological situation is typical for areas where mining enterprises, large industrial centers are located, as well as for areas that are characterized by a low level of environmental stability of natural geosystems.
