DETERMINATION OF HYDRO-ECOLOGICAL FACTORS OF THE VOLGA-CASPIAN AQUATIC ECOSYSTEMS STABILITY IN DESIGNING THEIR PROTECTION

摘要

This paper discusses possible consequences of changes in the Volga-Caspian aquatic ecosystems resulting from climate change according to the data scenarios of the Worldwide Meteorological Organization. Main hydro-ecological factors of stability of the Northern Caspian Sea ecosystems have been determined. It appears that ecosystem stability in the Northern Caspian Sea is primarily affected by natural conditions. It is essential to model riparian ecosystem processes and winter regime of reservoirs to develop strategies for mitigation of negative impacts of climate change. Such measures may include improvement of existing dams in the Volga region.
