摘要

Slovakia is situated in Central Europe of temperate climatic region. Climatic oscillations (greenhouse effect) as well as human activity in different economical conditions are more or less significant on global soil change and land degradation especially since 1990 year. By the influence of global warming also in temperate climate regions the extension of more or less dry period is often indicated especially during last decade. Further also medium and strong mineralisation of groundwater has been confirmed. It can indicate the next development of alkaline and saline soils in the warmest regions of Slovakia referring to global climate change. Soil acidification has developed particularly in soils developed mostly on acidic parent materials particularly under humid conditions. The decrease of humus content is remarkable in all arable soils. In general, on the basis of obtained results it may be said that soils in Slovakia are not polluted. Not more than 0.4 % of soil cover is strongly polluted. The change of heavy metal content in soils is not significant during last decade. The result of a soil global change depends to a great extent on its degree of reversibility. Finally, irreversible change is related to land degradation.
