20.500.12556/RUL-149254 Intercepcija snežnih padavin glede na razvojno fazo smrekovih sestojev na Pokljuki Snowfall interception based on the development phase of spruce stands in Pokljuka Za smrekove sestoje na Pokljuki je bil analiziran vpliv razvojne faze in zastrtosti s krošnjami na intercepcijo snežnih padavin. Debelina snežne odeje, razvojna faza sestojev ter zastrtost s krošnjami so bili določeni iz podatkov laserskega skeniranja površja pred in po sneženju za vseh 225 ploskev velikosti 30 × 30 m. Za določitev mejnih višin za posamezne razvoje faze, so bila na terenu dodatno izmerjena nepoškodovana drevesa (n = 113). Za višino snežne odeje na prostem so bile izbrane meritve iz najbližje meteorološke postaje – Rudno polje. Ugotovitve kažejo, da ima razvojna faza gozda statistično značilen vpliv na intercepcijo snežnih padavin, ki je v mlajših in starejši razvojnih fazah nižja. Prav tako rezultati kažejo, da ima tudi zastrtost s krošnjami statistično značilen vpliv na intercepcijo snežnih padavin, ki narašča z naraščanjem zastrtosti s krošnjami. The influence of development stage and canopy cover on snow interception was studied in spruce stands in Pokljuka. Snow cover height, stand development stage, and canopy cover were determined by laser scanning before and after snowfall for all 225 30 × 30 m plots. Undamaged trees were also measured in the field to determine threshold heights for each developmental stage (n = 113). For snow cover height in open areas, measurements from the nearest meteorological station - Rudno polje - were selected (3 km). The study shows that the stage of forest development has a statistically significant effect on snowfall interception, which is lower in younger and older stages of development. The results also show that canopy closure has a statistically significant effect on snowfall interception, which increases with increasing canopy closure. snežna hidrologija intercepcija snežnih padavin smrekovi sestoji lasersko skeniranje snow hydrology snowfall interception spruce stands laser scanning true false false [N.
