Abstract Miljevačko područje dio je Sjevernodalmatinske krške zaravni. Nalazi se u trokutu između rijeke Krke, Čikole i planine Promine, a zauzima površinu od 264,89 km2. Geomorfološkom analizom obuhvaćena su morfometrijska i morfogenetska obilježja reljefa. Na temelju izračunatih vrijednosti hipsometrije, nagiba padina i vertikalne raščlanjenosti reljefa uočeno je da je krška zaravan najzastupljenija u hipsometrijskom razredu 200-300 m/nv (74,93%) s prevladavajućim nagibima padina 0-5° (78,27%) na zaravnjenom terenu i slabo raščlanjenim ravnicama (0-30 m/km2). U vezu sa morfometrijskim parametrima reljefa dovedene su i ponikve – dijagnostički oblik krškog reljefa. Kartirano je 286 ponikava. Prosječna gustoća iznosi 1 pon/km2 što ovo područje svrstava u prostor s neznatnom gustoćom prema dosadašnjim istraživanjima ponikava na teritoriju RH. Statističkom analizom prostornog rasporeda i distribucije ponikava ustanovljen je vrlo visok stupanj povezanosti ponikava sa prevladavajućim morfometrijskim kategorijama. U okviru endokrškog reljefa uočena je zastupljenost speleoloških objekata jednostavne morfologije i malih dimenzija. S obzirom na vrstu objekata na istraživanom području prevladavaju jamski objekti (64%). Najviše speleoloških objekata nalazi se na zaravni (56%), u istim morfometrijskim kategorijama kao i ponikve. 40% speleoloških objekata nalazi se u kanjonu Čikole i Krke gdje prevladavaju špiljski objekti za razliku od jama koje su više zastupljene na zaravni. Uz morfometrijska obilježja reljefa analizirana su i strukturnogeomorfološka i egzogeomorfološka obilježja. Uz dominantni krški reljef, na istraživanom području izdvojeni su još fluvijalni, fluviokrški, padinski i antropogeni morfogenetski tip reljefa.
Abstract (english) Miljevci plateau is part of the North-Dalmatian karst plateau. It's situated between Krka river, Čikola river and mountain Promina with total area of the 264,89 km2. As a part of the geomorphological analysis, morphometric and morphogenetic characteristics were distinguished. Based on calculated values of the hypsometry, slope and vertical relief dissection it’s noticed that most prominent occurrence of karst plateau is linked with the areas ranging 200-300 meters of altitude (74,93%), slope inclination 0-5° (78,27%) and plain relief and weakly dissected plains (0-30 m/km2). Further more, dolines are considered as diagnostic forms of karst. The influence of morphometric parameters on the spatial distribution of the dolines are analysed as well. A total of 286 dolines has been identified in the researched area. According to the recent investigation of doline density on territory of Croatia, this area is classified in area with very low doline density since Miljevci plateau has just 1 doline/km2. A high degree of connection among dolines and prevailing geomorphometric categories is established. Moreover, speleological objects with simple morphology and small dimensions are most frequent. Considering a type of the speleological objects, pits prevail in this area. Most speleological object are found on the plateau (56%) in the same morphometric categories as dolines. 40% of the speleological object are found in canyon of the Čikola and Krka river where caves prevails unlike the pits which are more represented on the plateau. Beside morphometric features of the terrain this paper analyses structural-morphologic and exogeomorphologic characteristics. Along karst relief, fluvial, fluvio-karst, slope and anthropogenic morphogenetic types of the relief formation are determined too.
