Presoja ocenjevanja količine poseka na stalnih vzorčnih ploskvah = Evaluation of felling assessment by using data form permanent samplings plotsBončina, Andrej ; Hladnik, David ; Kadunc, AlešNa podlagi periodičnih meritev dreves na stalnih vzorčnih ploskvah (n = 1.604)v obdobju desetih let smo na primeru treh gozdnogospodarskih enot (Grčarice, Logatec in Vzhodne Haloze) analizirali ... kakovost podatkov, količino poseka, ocenili zanesljivost ocene poseka po različnih postopkih in ocene ugotovljenega poseka primerjali z uradnimi evidencami poseka. Pri oceni posekaje treba upoštevati petletni prirastek dreves, ki so posekana v desetletnem obdobju, sicer je posek podcenjen za približno 10 %. Zanesljivost ocene količine poseka je podobna, če uporabimo algoritem za (enostavno) slučajnostno vzorčenje ali pa algoritem za sistematično vzorčenje. Količina poseka, ugotovljena na stalnih vzorčnih ploskvah, se ne porazdeljuje normalno, vendar smo s primerjalno analizo poseka z metodo Bootstrap ugotovili,da je dopustna uporaba postopkov, ki predvidevajo normalno porazdelitev vrednosti. Ugotovili smo, da so uradne ocene o količini poseka podcenjene. V prispevku opozarjamo na pomanjkljivosti v postopkih in podatkovnih zbirkah, ki vplivajo na kakovost ocen, in predlagamo izboljšave.Source: Gozdarski vestnik = Slowenische Forstzeitung = Slovenian journal of forestry : slovenska strokovna revija za gozdarstvo. - ISSN 0017-2723 (Letn. 68, št. 3, apr. 2010, str. 135-144)Type of material - article, component part ; adult, seriousPublish date - 2010Language - slovenianCOBISS.SI-ID - 2942630
