AN EXPERIENCE OF FORECASTING POSSIBLE CHANGES IN THE NATURAL ENVIRONMENT IN THE CONSTRUCTION AREA OF A LARGE HEAT AND POWER ENGINEERING OBJECT (ON THE EXAMPLE OF SAKHALIN GRES-2)

Abstract

The paper describes an experience of forecasting possible changes in the components of the natural environment in the areas of a thermal power station construction (as applied to the key site of the Tomarin district in the Sakhalin region). The supplements are proposed to methodological approaches aimed at forecasting possible infringements in the components of the natural environment. The author's developments are based on the field research of the territory and landscape mapping using GIS on the basis of the analysis of topographical maps and remote probing data. A landscape map of the key site is constructed. Areas of dispersion of pollutants into the atmosphere from mobile and stationary sources of Sakhalin GRES-2, which were identified on the basis of calculations, are superimposed on the landscape map and the most polluted geosystems are selected. It is proposed to rank into three levels the vegetation damage zones caused by an increase in background concentrations of aerotechnogenic pollutants as a result of the construction of Sakhalin GRES-2. A map of the affected areas of plant complexes of the key research area is constructed.
