20.500.12556/DiRROS-7614 Monitoring in analiza zaraščanja kraške krajine v GIS okolju Monitoring and analysis of spontaneous afforestation of Karst landscape in GIS environment Članek predstavlja raziskavo zaraščanja kraške krajine. Pri analizi smo uporabili tehnike daljinskega zaznavanja, multitemporalne analize satelitskih slik v GIS okolju in statistične regresijske modele. Gozdnatost se je od leta 1935 povečala od 50,4% na 67,9%. Z regresijskim modelom smo pojasnili 71% celotne variabilnosti. Dejavniki, ki so največ prispevali k pojasnitvi zaraščanja so: nadmorska višina, razdalja do gozdnega roba, delež zaraslih površin v predhodnem obdobju, delež kmetijskih zemljišč in dve variabili, ki opisujeta intenzivnost kmetijske rabe. Če se procesi zaraščanja ne bodo bistveno spremenili, lahko do leta 2020 pričakujemo nadaljnje povečevanje gozdnatosti na 72,5%. This article presents Karst landscape spontaneous afforestation research. Remote sensing techniques, multitemporal analyses of satellite images in the GIS environment and statistical regression models were used in the research. Since 1935, the abundance of forests in this area has increased from 50.4% to 67.9%. About 71% of variability was explained with a regression model. Spontaneous afforestation is strongly influenced by the following factors: altitude, distance to the forest edge, share of afforested area in previous time periods, share of agricultural land, and two variables describing the intensity of agricultural use. Although various demographical, socio-economic and agro-structural factors were analysed in this research study, their influence on the process of spontaneous afforestation could not be established. If there are no significant changes in the processes of spontaneous afforestation in the future,forest abundance can be expected to increase to 72.5% by the year 2020. zaraščanje GIS Kras analiza krajine daljinsko zaznavanje Landsat Ikonos spontaneous afforestation GIS Karst landscape analysis remote sensing true false true Slovenski jezik Angleški jezik Znanstveno delo 2017-07-12 09:18:35 2017-07-12 09:18:35 2022-08-12 14:06:36 0000-00-00 00:00:00 2004 0 0 str. 21-52 Vol. 75 2004 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630* 0351-3114 URN:NBN:SI:doc-CB7IQOXX 1436582 6206978 RAZ_Hocevar_Milan_i2004.pdf RAZ_Hocevar_Milan_i2004.pdf 1 82878943142EAA0465B39BC2D02FE159 7b7e0a40fcf520e7efdc9f58f18fd16d980476b71b4ba72f8404772d74f7892a 1d7458d7-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/b2b3964e-9d03-4e3d-9fce-a11a3a556014 https://dirros.openscience.si/Dokument.php?lang=slv&id=9480 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
