Abstract. Geoecological analysis of territories includes the assessment of individual types of anthropogenic impact and then a comprehensive conclusion about the state based on the obtained indicators of anthropogenic impact. At the same time, geoecological studies are often carried out for territories with clear boundaries, for example, administrative-territorial entities. In natural systems, boundaries are usually transitional, so it is difficult to identify their clarity. In view of this, river basins with defined boundaries drawn along watersheds are a convenient object for conducting such studies, on the one hand. Conversely, the proximity of rivers within river basins significantly influences population settlement and overall territorial development, thereby determining the intensity of economic growth. In the presented work, an analysis of residential, mining, and agro-economic load in the Archeda River basin was carried out. When analyzing the residential load, the population settlement system of the territory was described, the types of settlements were identified. The mining and engineering component of anthropogenic impact is characterized through the mineral resource base and active and identified mineral deposits. Agro-economic impact is assessed by decoding Earth remote sensing data and vectorization of agricultural lands. A comprehensive assessment of anthropogenic impact is based on identifying area characteristics of individual types of anthropogenic impact using the QGis geoinformation system. Analysis of the obtained data allows us to conclude that agricultural activity (crop growing) predominates in the basin under consideration. Nevertheless, the intensity of economic development requires measures to rationalize it to ensure conditions for sustainable development.
Key words: river basin, Archeda River, QGis geoinformation system, geoecological assessment, anthropogenic impact.
