Hodzinska I. Geographical features of formation and current state of the reclamation system of the Bahna Valley

The dissertation research is devoted to the study and complex analysis of the geographical features of the formation and current state of the Bahna landscape reclamation system (LRS). The prehistory of reclamation system creation is considered and four stages of its formation are singled out; the influence of natural conditions of the territory on the creation of a reclamation system in the Bahna Valley is revealed. The morphometric indicators of the valley relief are analyzed. The general characteristics of the reclamation drainage system in this area and its main parameters are represented. The dynamics of the main forms of nature management during 2004–2016 within the Bahna Valley is characterized. The peculiarities of the current state of the natural environment in the Bahna Valley are studied and some recommendations for improving the ecological condition within the valley are offered. As a result of landscape reclamation, LRSs are formed, which consist of three blocks: natural, technical and managerial. The creation of optimal LRS is possible only on the basis of scientifically based design, which requires compliance with certain principles. The main elements of the LRS in the drained areas include: drainage system, water intake and hydraulic structures. Today in Ukraine the main way to drain wetlands is tile drainage. Important environmental measures that should be implemented to improve and maintain a stable ecological condition within the Bahna Valley may be: regulation of water and air regime of soils on drained lands; water protection, soil protection and forest protection measures; protection of flora and fauna.
