20.500.12556/RUL-68456 Meritve in analiza prestreženih padavin navadne breze (Betula pendula Roth.) in rdečega bora (Pinus sylvestris L.) v urbanem okolju Measurements and Analysis of Intercepted Precipitation of Silver Birch (Betula pendula Roth.) and Scots Pine (Pinus sylvestris L.) in Urban Area Študija prikazuje meritve, primerjavo in analizo prestreženih padavin iglastih in listnatih dreves. Meritve so se izvajale na raziskovalni ploskvi v urbanem predelu mesta Ljubljane in sicer na dveh skupinah dreves: navadne breze (Betula pendula) in rdečega bora (Pinus sylvestris). Analize in primerjave prepuščenih padavin in odtoka po deblu so narejene za obdobje od junija 2004 do decembra 2006, ki je bilo razdeljeno na štiri vegetacijska obdobja. Padavine nad drevesnimi krošnjami so se merile z ombrografom z avtomatskim zapisovanjem rezultatov na vsakih 10 minut ter s Helmanovim dežemerom z ročnim odčitavanjem za kontrolo. Prepuščene padavine so se merile s kombinacijo stalnih (korita) in pomičnih merilcev (totalizatorji) z avtomatskim zapisovanjem na 10 minut in ročnim odčitavanjem. Odtok po deblu se je meril ročno na po enem drevesu vsake vrste. Rezultati meritev so pokazali, da breze prepustijo 57-70 %, bori pa 35-49 % padavin, kar je primerljivo z rezultati drugih podobnih študij po svetu. Odtok po deblu je bil pri brezi 1,1-6,7 % padlih padavin in pri boru praktično zanemarljiv. Study presents measurements, comparation and analysis of intercepted precipitation of coniferous and deciduous trees. Measurements were made on experimental plot in the urban part of the city Ljubljana on two groups of trees: Betula pendula and Pinus sylvestris. Analyses and comparations of throughfall and stemflow were made for the period from June 2004 till December 2006 which was devided onto four vegetation periods. Rainfall above the canopy was measured automatically with a tipping bucket rain gauge with digital recording of results every 10 minutes in combination with manual Helman's rain gauge for control. Throughfall was measured using a combination of fixed gauges with digital recording of results every 10 minutes and manual roving gauges. Stemflow was measured manually on one tree of each specie. The results of the measurements showed that the throughfall for Betula pendula was 57-70 % of precipitation and for Pinus sylvestris 35-49 % which is comparable with the results of other similar studies around the world. The stemflow fraction for Betula pendula amounted 1,1-6,7 % of precipitation and it was practically negligible for Pinus sylvestris. prestrežene padavine breza bor prepuščene padavine odtok po deblu rainfall interception Betula pendula Pinus sylvestris throughfall stemflow true false false Zveza gozdarskih društev Slovenije Neznan jezik Neznan jezik Delo ni kategorizirano 2015-07-10 21:05:00 2015-07-10 21:05:00 2022-11-22 10:42:02 0000-00-00 00:00:00 2008 0 0 406-416 9 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0017-2723 Sraj_GV_2008_k.pdf Sraj_GV_2008_k.pdf 1 A9153182B271688E5E782D1A233F1129 209ffb0aa359a141d17067fdf354fa7f191c8ae4f3520ec273ec49909acb8f25 16b0c4e9-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/9fd943cb-2807-4dce-8854-3b53c2ef2a26 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=85736 Fakulteta za gradbeništvo in geodezijo 0 0 0
