Stanje in stanovitnost krajinskih gradnikov na območnih enotah Kranj in Ljubljana Zavoda za gozdove Slovenije : diplomsko delo - univerzitetni študij - 1. stopnja

Okršlar, Gašper (author), Hladnik, David (mentor)

V diplomski nalogi je bil ocenjen pomen krajinskih gradnikov v Območnih enotah Kranj in Ljubljana Zavoda za gozdove Slovenije. Zasnovana je bila metodologija, ki z analizo digitalnih orotofoto posnetkov omogoča popis krajinskih gradnikov - drevnine izven gozda. Popis poteka na vzorčni mreži 500x 500 metrov, vzorčne ploskve pa so razporejene samo na negozdnih površinah. Na krožnih ploskvah s površino 20 arov so bila popisana posamezna drevesa, skupine dreves, zaplate, posamezni grmi, skupine grmov ter zaplate grmičevja in ocenjen delež pokrovnosti ter višina krajinskih gradnikov. Po popisu so bile prikazane porazdelitve na celotnem območju popisovanja ter podrobna analiza v izbranih šestih krajinskih podenotah. Poleg trenutnega stanja (2012) so bile ocenjene tudi razlike v pokrovnosti leta 2001 in stanovitnost krajinskih gradnikov. Ocenjena je bila velika stanovitnost, pri analizi sprememb pa ugotovljen trend krčitev, ki je bil v primerjanem obdobju v Ljubljansko-Kamniški kotlini ocenjen na 3,9 % vzorčnih ploskev.

• Title: The state and stability of landscape elements in regional units Kranj and Ljubljana of the Slovenia forest service

Abstract

The Diploma thesis assesses the importance of landscape elements in the regional units Kranj and Ljubljana of the Slovenia Forest Service. A methodology was developed, which allows a census of landscape elements - trees outside the forest - by analysing digital orthophoto images. The census covers an area of 500 x 500 metres, and the sampling plots are situated on non-forest plots only. On circular plots of 20 ares each, individual trees were censused, as were groups of trees, patches, individual bushes, groups of bushes and bush patches, and the cover proportion and height of landscape elements were assessed. Following the census, the distribution over the total censused area and a detailed analysis for the selected six landscape sub-unitswere presented. Besides the current state (2012), the differences in the cover from 2001 and in the stability of landscape elements were also assessed. Major stability was assessed, and in the analysis of the changes a deforestation trend was observed, which was assessed at 3.9 % of sampling plots in the comparison period in the Ljubljana - Kamnik basin.
