Rychak N. 3Spatial-temporal peculiarities of heavy metals behaviour in soil covers of urban landscapes (on the example of Kharkov)

Object of research: soil cover of urban landscapes with regard to their spatial-temporal heterogeneity. Purpose of research: determinating of the main factor of heave metals spatial behaviour peculiarities forming in urban landscape soil cover taking into account heave metals temporal behaviour (more than 100 years) so as to base the ways of management of urban environment. Methods: landscape–ecological, landscape- geochemical est. Results and novelty: different temporal soil covers were used for scientific analysis; buried soil covers as a natural factor of forming present urban landscape were analyzed and their influence on the modern urban landscape forming was estimated; peculiarities of heave metals spatial - temporal behaviour by comparison of buried and present soil cover on various landscape- geochemical levers were determined; the approaches to management of urban ecological safety by influence on urban soil cover quality. Sphere of use: constructive geography, management of urban soils andurban landscape
