Danilchenko O. Geoecological analysis of river basins in Sumy region

Theoretical and methodical aspects of geoecological analysis of river basins of the region (its essence, scientific approaches, principles, basic notes) have been presented. The appropriate conception and algorithmic model of geoecological analysis of regional river basins are made. The conditions for river flow formation (natural and anthropogenic) have been analyzed, unfavourable natural processes, caused by constant water flow and aggravated by man's activities have been detected. The peculiarities of hydrological characteristics and hydrological regime of rivers in Sumy region have been defined. Hierarchical structure of hydrological regional systems have been determined and described, three levels of landscape and hydrological differentiation have been distinguished - zonal, provincial and district, as a result the landscape-hydrological zoning has been executed.
