Owing to the apprehension of pollution and degradation of soils, a need became urgent to protect this natural sphere and prevent its further pollution. Individual properties of prevailing soils in the valley of the Dravinja and its tributaries, the Brežnica and the Ličnica (northeast of Poljčane), and a brook in the Dravinjske gorice north of Poljčane, were numerically evaluated by applying certain selected criteria for the ecological evaluation of soil. Namely, the valley bottoms are exposed to the ever greater pressures due to intensive land use, as well as owing to some new forms of land use. Since the selected valleys still have "natural" appearances, our interest is focused on their possible changes were the current land use changed (prevailing are hydrophilous meadows). Namely, by means of the ecological evaluation of the soil, its responses to human interventions can be establishedPomen ekološkega vrednotenja prsti je povezan s poudarjanjem pomena trajnostnega razvoja v zadnjem desetletju. Zaradi spoznanj o onesnaženosti in degradiranosti prsti se je pojavila potreba po varovanju in preprečevanju njenega nadaljnjega onesnaževanja. Po izbranih merilih za ekološko vrednotenje prsti so bile številčno ocenjene posamezne lastnosti prevladujočih prsti v dolini reke Dravinje in njenih pritokov Brežnice in Ličnice (severovzhodno od Poljčan) ter potoka v Dravinjskih goricah severno od Poljčan. Dolinska dna so namreč izpostavljena vse večjim pritiskom zaradi intenzivne rabe kakor tudi uvajanja novih oblik rabe. Ker izbrane doline še kažejo "naravni" videz, nas je zanimalo, kaj bi se z njimi zgodilo, če bi se sedanja raba tal spremenila (prevladujejo vlagoljubni travniki). Z ekološkim vrednotenjem prsti lahko namreč ugotovimo odziv prsti na antropogene posegeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza geografov Slovenije
