In order to optimize consumption, maintenance and control of underground water, an estimation of the groundwater recharge is highly important. Therefore, this research investigates the aquifers in North Khorasan province using APLIS (Applied Physics Laboratory Ice Station) based on a GIS. For this purpose, several significant hydrogeological parameters affecting groundwater recharge including altitude, slope, lithology, soil type and infiltration are considered. Therefore, corresponding layers for these parameters were provided and prioritized. In the end and after integrating the data, the recharge rate was measured qualitatively and different regions were mapped accordingly. The results indicate that the annual average values on a 30-year timescale in karst formations of the North Khorasan vary between 103 mm and 362 mm, with the mean value of 192 mm. Minimum, maximum and mean recharge rates of aquifer in the study area are 42 %, 73 % and 54 %, respectively. Also, aquifer recharge potential in 83 % of the karst formations is moderate while it is high for the remaining. Low recharge regions correlate to lower karst limestone and dolostone areas in the lower altitudes while high recharge regions represent upper karst limestone and dolostone areas, especially in the high altitudes. Key words: Groundwater resource management, Recharge, APLIS, GIS, karst, North Khorasan.  Ocenjevanje napajanja podzemne vode v kraskih vodonosnikih v severnem Horasanu, v Iranu, z uporabo metode APLIS  Za optimizacijo porabe, vzdrževanja in nadzora nivoja podzemne vode je ocena napajanja vodonosnika zelo pomembna. Zato raziskava z uporabo metode APLIS, ki temelji na GIS, raziskuje vodonosnike v provinci Severni Horasan v Iranu. Pri tem smo upostevali vec pomembnih hidrogeoloskih parametrov, ki vplivajo na napajanje vodonosnika, vkljucno z nadmorsko visino, naklonom, litologijo, tipom tal in infiltracijo. Za vsakega od parametrov smo pripravili informacije v ustreznih oblikah. Po obdelavi in integraciji podatkov smo izracunali hitrost polnjenja vodonosnika. Razlicne regije smo ustrezno ovrednotili. Rezultati kažejo, da se v kraskih formacijah Severnega Horasana letne povprecne vrednosti v 30-letnem casovnem obdobju gibljejo med 103 mm in 362 mm, s povprecno vrednostjo 192 mm. Najmanjse, najvisje in povprecne stopnje polnjenja vodonosnika v studijskem obmocju so 42-, 73- in 54-odstotne. Tudi potencial polnjenja vodonosnika je v 83-odstotnih kraskih formacij ocenjen kot zmeren, za preostale predele je ocenjen kot visok. Obmocja z nizkim potencialom polnjenja so povezana z nižje ležecimi zakraselimi apnenci in dolomiti, visje ležeca obmocja predstavljajo apnenci in dolomiti z visjim potencialom polnjenja.  Kljucne besede: upravljanje podzemnih vodnih virov, napajanje, APLIS, GIS, kras, Severni Horasan.
