VARIJABILITET I PRECIZNOST PROCJENE TAKSACIONIH ELEMENATA VJEŠTAČKI PODIGNUTIH SASTOJINA BIJELOG I CRNOG BORA NA PEŠTERSKOJ VISORAVNI Metodom uzorka istraživan je varijabilitet i preciznost procjene taksacionih elemenata stabala i sastojina bijelog i crnog bora. Odabrane su četiri karakteristične sastojine ovih vrsta drveća koje su nastale pošumljavanjem goleti na Pešterskoj visoravni. Starost sastojina je 25-30 godina, a bonitet staništa različit. S obzirom na smjesu radi se o čistim i mješovitim sastojinama. Sastojine su jako homogene, sa varijacionim koeficijentom zapremine oko 25% (pri velicini probne površine 2 ara, oblika kruga). Sa uzorkom veličine 10 probnih površina postignuta je preciznost procjene zapremine ±18%, a sa veličinom uzorka 15 probnih površina ±14%, pri vjerovatnoći 95%. The variability and precision of assessment of cruising elements of Scots pine and Austrian pine trees and stands was studied by sample method. The four selected characteristic stands of these tree species were established by afforestation of barrens on Pesterska Visoravan. Stand age was 25-30 years, site classes different. As for mixture, they were pure and mixed stands. The stands were highly homogeneous, with variation coefficient of volume about 25% (sam pie plot size 2 ares, in the form of a circle). The sample size of 10 sample plots achieved the precision of volume assessment ± 18%, and the sample size of 15 sample plots achieved ±14%, probability 95%. https://unilib.phaidrabg.rs/o:6485 ISSN: 0354-1894 2004 stablo, sastojina, bijeli bor, crni bor, uzorak, statistika, inventura suma, varijabilitet, preciznost, tačnost. tree, stand, Scots pine, Austrian pine, sample, statistics, forest inventory, variability, precision. info:eu-repo/semantics/article All rights reserved application/pdf 4913317 bytes Koprivica, Miloš Zbornik radova Instituta za šumarstvo number: 50-51 startpage: 5 endpage: 21 srp Institut za šumarstvo
