| مستخلص: | Biokovo Mt is part of the Outer Dinarides, in a coastal position with a NW-SE main tectonic orientation. The highest peak called Sveti [Sv.] Jure (1762 m) towers above a karst plateau of 1300-1400 m mean elevation. Both of the long margins of Biokovo are characterized by steep and high relief energy rockwalls formed along tectonic fault lines. The plateau is intensely karstified with diverse karren forms, large dolines and several shaft caves. Its unique karstmorphological features are the relatively deep dolines with steep walls, so the landscape is characterized mainly by the sharp interdoline ridges and pyramidal peaks instead of negative doline forms. Based on the previous observation, the Biokovo plateau can be considered a „polygonal karst”. The geomorphological map of a study area from this plateau has been elaborated, based on field observations and topographical maps. After digitizing the contour lines, we have created the digital elevation model (DEM) of the study area and carried out sophisticated doline-morphometrical analysis using the DEM. The most important and unique feature of the landscape, the polygonal structure, has been derived from the DEM using GIS hydrologic modelling tools. Planina Biokovo nalazi se na obali Jadranskog mora i dio je Vanjskih Dinarida s tipičnim dinarskim smjerom pružanja SZ–JI. Najviši vrh Biokova Sv. Jure (1762 m) izdiže se iznad krške zaravni koja se nalazi na visini od 1300 do 1400 m. Sjeveroistočna i jugozapadna padina Biokova nastale su duž glavnih rasjeda, vrlo su strme i velike su reljefne energije. Krška zaravan građena je od jurskih i krednih vapnenaca i dolomita te je intenzivno okršena. To se očituje u bogatstvu krških reljefnih oblika: škrapa, vrlo velikih ponikava i jama. Posebnost su krškog reljefa Biokova duboke ponikve vrlo strmih padina, tako da je krajobraz istraživanog područja više obilježen oštrim i uskim grebenima i visokim piramidalnim vrhovima koji međusobno odjeljuju ponikve nego udubljenjima. Na temelju dosadašnjih istraživanja biokovsku kršku zaravan možemo smatrati "poligonalnim kršem". Na osnovi terenskoga kartiranja i različitih analiza topografse karte načinjena je geomorfološka karta istraživanog područja površine od 3 km2 koje se nalazi jugozapadno od vrha Sv. Jure. Na temelju digitaliziranih izohipsa izrađen je digitalni model reljefa (DEM) istraživanog područja, koji je poslužio sofisticiranoj morfometrijskoj analizi ponikava. Poligonalna struktura dobivena je iz digitalnog modela reljefa uz pomoć GIS hidroloških alata. |
