Geoinformation-cartographic methods in the research of the ecological and economic balance of the territory

Estimation of the ecological and economic balance of the territory is important for developinga strategy for its rational use. A comprehensive account of the types of anthropogenic impact, the determinationof the corresponding anthropogenic load, and, ultimately, the natural protection of the land is a source forforming recommendations and conducting activities to maintain sustainable development. Currently, indomestic science there are examples of such an assessment for areas with different types of specialization:agricultural, agro-industrial, industrial, recreational, which indicates the relevance of such studies. The aim ofthis work is to assess the environmental and economic balance of the territory of Krasnoarmeysky district ofSaratov region using geoinformation mapping methods. The article successively describes the stages ofassessing the environmental and economic balance: collecting, processing, decoding satellite images ofSentinel and Landsat; compiling a database of vector objects by the type of economic use; calculating thecoefficients of anthropogenic load and natural protection of the territory based on statistical data obtained inthe geoinformation system. According to the absolute tension coefficient (Ka), 3 clusters are identified in theterritory of Krasnoarmeysky district: a cluster of medium intensity ECB (from 0.5 to 1), low (from 0 to 0.3) andlowered (from 0.3 to 0.5). Clusters of high degrees of tension are not allocated. According to the coefficient ofrelative tension (Ko), 2 clusters of low (from 0 to 2.5) and lowered (2.5-5) tension were identified. Clusters ofhigh degrees of tension, as in the previous case, were not identified. According to the coefficient of naturalsecurity of the territory, 2 clusters are identified. According to the Kez coefficient, the northwestern part of thedistrict refers to territories with average protection (0.43-0.49). The northeastern, central, and southern partsof the region belong to territories with increased (more than 0.5) security. Low (0-0.35) and lowered (0.36-0.42)natural security in the region is absent. The obtained values of the coefficients allow us to assess theeconomic development of the region as balanced
