They have a significant impact on water supply, nutrient cycling and dynamics of carbon in the ecosystem. In our study, the precipitation regime of the selected forest stands and gaps in the Snežna jamamanaged forest and in the Rajhenavski Rog virgin forest remnant has been determined. During the 2003 and 2004 growing seasons, throughfall and stemflowwere recorded in the gaps and forest stands. In the years 2001 till 2007, monthly precipitation in the open was measured. Precipitation measurements are rarely performed in forested landscapes, although they constitute an important input variable for process modelling in forest ecosystems. Substitution with measurements from the closest meteorological station is, due to their distance, questionable. Therefore we compared the measured precipitation in the open to daily and monthly precipitation at the Climatological Station Kočevje and EMEP Iskrba Station at Kočevska RekaKoličina, oblika in časovna razporeditev padavin so izrednega pomena za gozdne ekosisteme, saj pomembno vplivajo na preskrbo z vodo, kroženje hranil in dinamiko ogljika v ekosistemu. Namen naše raziskave je bil analizirati padavinski režim v dveh sestojih in vrzelih različne velikosti v dinarskem jelovo-bukovem pragozdnem rezervatu Rajhenavski Rog ter v gospodarskem sonaravnem gozdu Snežna jama. V vegetacijskem obdobju v letih 2003 in 2004 smo spremljali prepuščene padavine in odtok po deblu v vrzelih in sestojih, padavine na prostem pa v letih od 2001 do 2007. Meritve padavin v gozdni krajini so redke, čeprav so pomemben vhodni podatek za modeliranje procesov v gozdnih ekosistemih. Uporaba meritev z najbližjih meteoroloških postaj je zaradi njihove oddaljenosti vprašljiva, zato smo dnevne in mesečne količine padavin na prostem primerjali z vrednostmi za klimatološko postajo Kočevje ter EMEP-postajo Iskrba pri Kočevski RekiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
