Abstract
Obravnavali smo vidnost daljnovodnih presek, spreminjanje dolžine gozdnega robu in površine poseka ob upoštevanju različnih višin dreves (med 15 in 35 m). Izbrana metoda dela je potekala v GIS programih. Namen naloge je bil prikaz možnosti oblikovanja daljnovodne poseke in spreminjanje vidnosti različnih širin preseke v okolici. Izbran je bil odsek daljnovoda med planoto Hrušice in Postojnskim poljem, v dolžini 11024 m, v analizi je bilo vključenih 30 stojnih mest. Območje s katerega so vidni daljnovodni stebri, je obsegalo 33,7 % oz. 4823,3 ha izračunane celotne površine. Povprečni delež območja, s katerega so vidne različne širine preseke, je bil 30,3 %. Z največ površin (14,3 %) je bil viden samo en steber. Območje, s katerega sta vidni varianti trase 1 in 2 (šest določenih stebrov), obsega 2395,1 ha oz. 3586,2 ha veliko površino, slednja je glede na obstoječo traso vidna z največ območij. Območje, s katerega so vidne različne širine preseke pri določenih višinah drevja (15, 25 in 35 m) je v povprečju obsegalo 4338 ha. Enotna širina koridorja 40 m je bila vidna s 4327,5 ha. Število lokacij poseka se je zmanjševalo z velikostjo dreves. Največja površina poseka (39,9 ha) in dolžina gozdnega robu (15 km) sta bili pri višini drevja 35 m in najmanjši pri višini 5 m (1,9 km in 0,7 ha). Razlike v dolžini gozdnega robu in površini poseka so se zmanjševale z višino drevja.

Title:Transmission lines in the forest areas
Abstract:
The purpose of the thesis was to show the possibility of changing visibility of transmission line, creating powerline clearings and changing the length of forest edge, taking into account the different heights of trees (between 5 and 35 m). The section of transmission line between Hrušica plateu and Postojna basin was selected. The length of section was 11.024 m. The analysis included 30 standing places. Viewport of transmission towers covered 33,7 % (4823,3 ha) of total calculated area. The viewport of two imaginary spatial placments of transmission line covered 2395,1 ha and 3586,2 ha. The viewport of the second variant was grater than the viewport of existing transmission line. The average proportion of the visible area of different transect width was 30,3 %.The area of visibility comprised 4395,5 ha, at specified height of trees 35 m. Unified width of corridor (40 m) was evident with 4327,5 ha. Number of harvest locations has decreased with the size of the trees. Maximum surface of clearings (39,9 ha) and the length of forest edge (15 km) was calculated for height of trees of 35 m. The differences in the length of forest edge and surface of removals has decreased by the height of trees.
