ABSTRACT. - Considerations regarding the impact of human activities on hydro tourist resources related to karst aquifers from Arieş basin, upstream of Buru. The impact of human activities on hydro tourist resources related to karst aquifers from Arieş basin may have negative, but also positive effects, the antagonism being dictated by the way in which the determinants of risk phenomena and processes are implicated, with anthropogenic or natural in origin. The existence of a thin soil layer, as well as the presence of systemís large entrances, pits and sinkholes type, determinate the quick pollutants transfer and contamination or aesthetic degradation of karst aquifers. Hydro tourist resources afferent to karst aquifers are accessible through caves. Hydro entities due to endokarst morphology, flow rate types and climatic factors are revealed through underground rivers and lakes, ice deposits and karst streams. The negative impact of human activities on these resources endorse pollution with series of compounds or chemical fertilizers, dejections from septic systems, residues from animal ranches and aesthetic degradation by plastic waste accumulation in openings sinkholes type. The positive impact requires protection for representative natural areas and air, water and bio-soil-lithos layer quality control. The most damaged hydro tourist resources from the analyzed basin are associated to V‚nătara and Ocoale aquifers. 

Key words: hydro tourist resources, pollution, negative/positive impact, karst aquifer
