Abstract

U pojedinim dijelovima Republike Hrvatske veliku opasnost predstavljaju klizišta kojima kao prirodnoj prijetnji nije dovoljno posvećena pozornost. Klizišta mogu biti velike prijetnje po ljudske živote i prouzrokovati velike materijalne štete, a kako bi se to spriječilo ili ublažilo, potrebno je napraviti sustavnu bazu klizišta, karte ugroze od klizanja te educirati populaciju. U radu je izvršena GIS analiza podložnosti klizanja tla na području Banovine. Analizirane su prirodnogeografske značajke područja te antropogeni čimbenici koji utječu na nastanak klizišta. Dakle, uz morfometrijske značajke reljefa; hipsometriju, nagib padina, ekspoziciju, napravljena je geološka i morfogenetska analiza, analiza hidrografske mreže, klimatoloških i pedoloških obilježja područja te analiza antropogenog utjecaja kod zemljišnog pokrova i izgradnje cestovne mreže. Za svaku od tih kategorija određena je pojavnost klizišta. U konačnici, modelom omjera frekvencija (FR model) dobivene su vrijednosti koje su poslužile izradi karte ugroženosti padina klizištima na području Banovine. Vrijednosti FR modela predstavljaju u kolikoj je mjeri pojedini faktor utjecao na klizanje tla. Na temelju podataka FR modela i prateće mu karte, doneseni su zaključci te su predložene mjere prevencije i sanacije klizišta.

Abstract (english)

Landslides, which are not considered serious enough as a natural threat, represent a severe danger in certain areas of Croatia. Since the landslides can impose a serious threat to human lives and cause severe material damage, a system base of landslides, together with a threat map need to be created. In addition, educating people about the danger of landslides is equally important. This paper is based on a GIS analysis of susceptibility to landslides regarding the soil in the area of Banovina. The analysis includes physical-geographic features of the areas and anthropogenic factors which affect the creation of landslides. So, considering morphometric features of the relief, alongside hypsometry, slope and aspect, a few important anayses have been performed – geological and morphogenetic, the analysis of hydrographic networks, together with climatological and pedological features, and the analysis of anthropogenic affect to soil cover and road network construction. The manifestation of landslides has been determined for each of the above-mentioned categories. Ultimately, the values, which were of great importance when creating the threat map of the slopes in regard to the landslides in Banovina, have been obtained by the frequency ratio (FR) model. The values of FR model represent how much every factor affected the occurrence of landslides. Certain conclusions have been made and measures for prevention and remediation of landslides were proposed based on the data collected by the FR model.
