STUDY ON USE OF ARTIFICIAL WATER RESERVOIRS IN SILESIAN UPLAND (SOUTHERN POLAND) AS ELEMENT OF CULTURAL LANDSCAPE

Rzetala M., Rahmonov O., Malik I., Oleś W., Pytel S.: Study on use of artificial water reservoirs in Silesian upland (southern Poland) as element of cultural landscape. Ekologia (Bratislava), Vol. 25, Supplement 1/2006, p. 212–220. In result of industry and urbanisation development in upper Silesia some thousands artificial water reservoirs were originated. It caused many changes in the environment identified with transformation of cultural landscape. Management of them is unusually essential task promoted in support intentional and harmonious modelling of the neighbourhood (landscape architecture). Results of carried out field (level geodetic circuit) and laboratory (INAA, ICP, XRF) investigations allowed to state some regularities designating the importance of water reservoirs in landscape. Water quality in reservoirs is the basic factor deciding of character of their use as well as of management of littoral zone. The delicious indices of qualitative state of reservoirs waters are results of complex investigations on bottom deposits. Ranges of levels of trace elements occurrence in bottom deposits usually stray from levels of geochemical background. Temporal changes in trace elements content simultaneously indicate the largest transformations in water environment identified with period of socialistic economy and spontaneous nature regeneration which was typical for last a dozen or so years of marked economy development.
