Solar Activity And Water Content Of Closed Lake Ecosystems

The question of “helio-dependence” of water level fluctuations within the closed type lakes in the Ukrainian West Polesie nature protected areas has been considered in the paper. The method of correlation analysis was used to define the interrelation between helio- and geophysical processes in the part that provides the ecological safety of the territory. The analysis has shown that the Total Solar Irradiance Index is more informative than the one including sunspot numbers.
