Vpliv starosti gozdne ceste na zaraščanje brežin in svetlega profila

V diplomski nalogi se je ugotavljalo, kako na uspešnost zaraščanja brežin delujejo različni dejavniki. Ugotavljal se je predvsem vpliv starosti gozdne ceste, naklon brežin, nadmorska višina ter širina svetlega profila. V ta namen se je na treh različno starih gozdnih cestah izmerilo na vsaki po 50 prečnih profilov. Merile so se ceste na področju OE Bled. Omejilo se je na gozdne ceste zgrajene na trdi podlagi in z južno ekspozicijo. Ugotovilo se je,da nezaraščene brežine predstavljajo nevarnost pri vožnji po cesti, so bolj podvržene delovanju erozije in estetsko motijo podobo gozda. Iz meritev seje prišlo do zaključka, da so bolje zaraščene brežine starejših kot mlajših cest. Tako se je ugotovilo, da na zaraščenost brežin najbolj vpliva čas, ki je minil od gradnje gozdne ceste in širina svetlega profila ter z njo povezana količina svetlobe in toplote, ki pride do tal. Manj pa na zaraščenost vplivata naklon in nadmorska višina. Potrebno je poudariti, da je za uspešno zaraščene brežine pomembno predvsem skupno delovanje vseh omenjenih dejavnikov.This thesis focuses on a survey of how different factors affect the escarpment over growing. Our main foci were the impacts of the age of the forestroads, escarpmentʼs incline, altitude, and the impact of the width of the clearance. Fifty transverse profiles were measured on each of the three forest roads of different ages. The measuring range encompassed forest roads in the Bled areaŽspecifically, forest roads that were built on solid grounds in the southern areas. Escarpments that are not overgrown represent a danger to the drivers of the road, they are more subjected to erosion, and are not aesthetic. The survey revealed that escarpments of older roads are more overgrown than the younger ones. Moreover, the survey confirmed that the most effective factors of the escarpment overgrowing are the time that has passed by since the road construction, the width of the clearance, and consequently, the quantity of the light and the heat that reach the ground, whereas the incline and the altitude are less affective factors. However, it needs to be pointed out that interaction of all factors is crucial for a successful escarpment overgrowing
