Abstract
V jugovzhodni Ljubljanski kotlini je veliko vodnih virov, ki se po dinamični zalogi, načinu obnavljanja, hitrosti pretakanja, debelini in prepustnosti krovne plasti ter po kakovosti zelo razlikujejo. Razdelili smo jih v šest skupin podzemnih voda glede na primernost vodnega vira za oskrbo s pitno vodo. Za oskrbo Ljubljane je treba zagotoviti približno 1,5m3/s pitne vode, zato bi ob onesnaženju podtalnico Ljubljanskega polja težko nadomestili. V jugovzhodni Ljubljanski kotlini imajo največjo dinamično zalogo pitne vode vodonosniki v nesprijetih sedimentih, izmed katerih smo za ocenjevanje pokrajinske občutljivosti izbrali štiri območja: Ljubljansko polje in vršaj Iške kot območji sedanjih virov pitne vode ter Sorško polje in Ljubljansko barje kot območji možnih virov pitne vode. Z vrednotenjem izbranih fizičnogeografskih lastnosti okolja s podtalnicami smo ugotovili, da je vodno ekološko najmanj občutljivo Ljubljansko barje, sledita Ljubljansko in Sorško polje, najbolj občutljivo pa je okolje s podtalnico na vršaju Iške.

Title:Landscape characteristics of the areas with drinking water resources in the southeast Ljubljana basin
Abstract:
There are numerous water resources in the northeast [i.e. southeast] Ljubljana basin which differ significantly as to their dynamic reserves, mode of resupply, baseflow speed, depth and permeability of cover layer, and quality. By suitability of these water resources for drinking water supply they are divided to six groups. It is necessary to provide about 1.5m3/s of drinking water for the supply of Ljubljana, and in case of pollution it would be very hard to substitude for the groundwater of the Ljubljansko Polje. In the southeast Ljubljana basin, the aquifers in nonconsolidated sediments have the greatest dynamic reserves of drinking water. Selected for the assessment of landscape sensitivity were four of them: the Ljubljansko Polje and the Iška alluvial fan as the areas of current drinking-water resources, and the Sorško Polje and the Ljubljansko Barje as the areas of possible resources. It has been established through the evaluation of selected physicogeographical features of the environment with groundwater that the Ljubljansko Barje is water-ecologically least sensitive, next come the Ljubljansko Polje and the Sorško Polje, while the Iška alluvial fan is the most sensitive environment with groundwater.
