Ecological and Geochemical Evaluation of Road Geosystems in Chernivtsi Region. Hodan G.D.
The thesis deals with theoretical and methodological foundations of ecological and geochemical analysis of road geosystems. It analyses the development of road system, its connection with physical and geographical conditions and geochemical peculiarities of landscape in Chernivtsi region. According to field and analytical studies the level of waysides pollution with heavy metals (Pb, Cd, Cu, Zn) is characterized. The thesis presents regional background quantity for vegetation of the explored territory. Due to the coefficient of heavy metal concentration in soil and vegetable cover the geochemical anomalies are detected. Schematic maps of anthropogenic waysides pollution are made. The index of saturation of soils is shortchanged by heavy metals.
Key word: ecological and geochemical evaluation, landscape, road geosystems, heavy metals, background content, index of soil saturation, pollution intensity, integral indicator of landscape pollution.
