20.500.12556/DiRROS-7665 Mikroklimatske razmere v vrzelih in sestojih dinarskega jelovo-bukovega gozda Microclimate conditions in gaps and mature stands of Dinaric silver fir-beech forests Mikroklimatske razmere sodijo med dejavnike, ki odločujoče vplivajo na zgradbo, rast, zdravstveno stanje in stabilnost gozdnih ekosistemov. Namen naše raziskave je bil raziskati osnovne mikroklimatske razmere v dveh sestojihin v vrzelih različne velikosti v dinarskem jelovo-bukovem pragozdnem rezervatu (Rajhenavski Rog) ter gospodarskem sonaravnem gozdu (Snežna jama) v vegetacijskem obdobju v letih 2003 in 2004. Spremljali smo temperaturo zraka, temperaturo tal, relativno zračno vlago ter smer in hitrost vetra. V pragozdnem rezervatu so bile povprečne dnevne temperature zraka na 2 m višine nižje kot v gospodarskem gozdu, relativna zračna vlaga pa je bila višja. V gospodarskem gozdu so bile v nasprotju s pričakovanji temperature zraka na sredini Male vrzeli (SMV) višje kot na sredini Velike vrzeli (SVV). Ugotavljamo, da na mikroklimatske razmere poleg zgradbe sestoja in oblikovanost roba vrzeli pomembno vplivajo tudi značilnosti razgibanega kraškega reliefa: naklon terena, ekspozicija ter oblikovanost terena. Microclimate conditions affect composition, structure, growth, health and dynamics of forest ecosystems. In the current study, microclimatic conditions of a Dinaric silver fir-beech forest in selected forest stands and different development stages in managed forest (Snežna jama) and virgin forest remnant (Rajhenavski Rog) were determined during two growing seasons in the years 2003and 2004. Air temperature, soil temperature, relative humidity, wind speedand direction were measured. Daily air temperatures 2 m above ground werelower in the virgin forest remnant than in the managed forest, but relative humidity was higher. Microclimate conditions in the managed forest were not more extreme in the Large gap (SVV) than in the Small gap (SMV), in contrast to our expectations. Microclimatic conditions are influenced not onlyby stand structure and shape of the forest edge in a gap but also by the karst relief characteristics: the inclination, exposition and shape of the terrain. mikroklima gozda gospodarski gozd pragozdni rezervati vrzeli tvorba vrzeli Kočevski Rog forest microclimate maneged forest virgin forest remnant gap formation Kočevski Rog true false true Slovenski jezik Angleški jezik Znanstveno delo 2017-07-12 09:18:50 2017-07-12 09:18:50 2022-08-12 14:11:01 0000-00-00 00:00:00 2006 0 0 str. 21-36 Vol. 81 2006 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*111(045) 0351-3114 URN:NBN:SI:doc-0ZM5JW4I 1806758 6206978 RAZ_Vilhar_Ursa_i2006.pdf RAZ_Vilhar_Ursa_i2006.pdf 1 AABE7DD7294F7C31BA81498734317E45 4b2dade297c701388e467dcee8d4e7530982ec52971869078cc9d92683f2eed9 212e1124-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/3996fc10-4c2f-49da-9d36-06ddb103b4ee https://dirros.openscience.si/Dokument.php?lang=slv&id=9530 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
