mountain ecosystem

The existing conceptual approaches to assessment of the environmental security of the Eastern Carpathians have been analyzed. The original vision of the mechanism for maintaining sustainable development in the Pokutsko-Bukovinian Carpathians mountain ecosystem is proposed. The methodological approach used to determine the ecological status and the level of environmental safety of mountain areas is based on the use of sanitary-ecological indicators as sensitive determiners of environmental changes under the influence of the anthropogenic factor.

The microbiological parameters of surface water as indicators of the ecological state of the Carpathians in Pokuttia-Bukovina region were studied. The water streams of the National Nature Park "Vyzhnytskyi", where a specific ecosystem has been formed for more than two decades, were used as a standard for comparison. The possibility of using "biofilters" based on a synthetic carrier "Viia" for purification of natural water streams and raising the level of ecological safety of mountain ecosystems has been proved.
