  Abstract:  Five soil samples from the Parâng Mountains in the South-Eastern part of the Hunedoara county, from five altitudinal vegetation zones (the alpine zone, the subalpine zone, the conifers zone, beech zone and the Maleia flood plain) were collected and these samples have been analyzed qualitatively enzymologically. In the soil samples, the following enzymatic activities have been qualitatively determined: four oligase activities: maltase, saccharase, lactase and cellobiase and three polyase activities: amylase, dextranase and inulinase. The studied activities were detected in all the 5 altitudinal vegetation zones, with differences noticed only in the intensity of the processes. Generally, the highest intensity of qualitative enzymatic activities were registered in soil samples from the conifers vegetation zone.
