Metamorphization of zonal hydrochemical composition of surface and groundwater of Ukraine under the influence of anthropogenic and natural factors
Abstract
An integrated method of functional diagnostics of basin geosystems through quantitative assessment of anthropogenic (drainage reclamation) or natural factors (climate) on the change of hydrochemical composition of surface and groundwater is presented. The method is based on the natural latitudinal and vertical zonation of the hydrochemical composition of surface and groundwater, as a manifestation of the geomembrane properties of the pedosphere. The stages of the quantitative assessment of the impact of increasing drainage reclamation areas in the Styr and Irpin river basins, were a linear regression analysis of chronological series of the content of each of the macrocomponents of the river water composition in the closing line for 1947-1989, and also the dynamics of increasing reclamation areas and correlation analysis of the obtained dependencies. To increase the closeness of the correlation, the hydrochemical composition was presented in %-equivalent form, which most accurately characterizes the ratio of macrocomponents, but does not depend on the total mineralization of water. A decrease in the content of such typomorphic ions as hydrocarbons and calcium and an increase in the content of other macrocomponents and mineralization were found statistically significantly with increasing drainage areas. In general, with increasing areas of drainage reclamation, there is an aridization of the hydrochemical composition of river water. The change of hydrochemical type of river water according to the classification of О.О. Alekina. The obtained parametric models of time trends of the content of macrocomponents of hydrochemical composition allowed to determine the limiting area of reclamation of the basins of two rivers and to predict changes in the hydrochemical type of water in the direction of its aridization.
Stopping the construction of new reclamation systems and reducing the efficiency of agricultural use of drained lands leads to the restoration of the hydrochemical composition of rivers in the direction of their reclamation development.
Approbation of the created method of functional diagnostics was carried out on five reclamation systems of Prykarpattia and in the basin of the Western Bug river and its branches proved its high efficiency and perspective for the creation of parametric models of the influence of natural and anthropogenic factors on chemical composition and quality of water resources.
