20.500.12556/RUL-176173 Pregled nedestruktivnih metod za ugotavljanje vitalnosti in kakovosti dreves Review of non-destructive methods for assesing the vitality and quality of trees V diplomskem delu je pregled nedestruktivnih metod za ocenjevanje vitalnosti in kakovosti živih dreves, pri slednjem s fokusom na detekciji notranjih napak lesa. V gospodarskem, še posebej pa v urbanem gozdu in parkih, je detekcija notranjih napak lesa (kot so npr. trohnoba in votline) ter vitalnosti ključna za pravočasno ukrepanje in zagotavljanje javne varnosti. V raziskavi so bile pregledane različne nedestruktivne metode, podana sta njihov opis in potencialna raba v gozdovih. Delo temelji na pregledu domače, predvsem pa tuje strokovne literature, ki raziskuje metode ocenjevanja kakovosti in vitalnost stoječih živih dreves. Ključna iskalnika literature sta bila spletni podatkovni bazi Google učenjak in Research Gate, pa tudi Science Direct in Web of Science. Na podlagi pregleda literature so bile analizirane invazivne in neinvazivne metode, in sicer akustična tomografija, metoda električnega upora, georadar, mikrovalovno skeniranje, rentgenska tomografija, klorofilna fluorescenca, šigometrija in refraktometri. Ugotovljeno je bilo, da posamezne metode različno prispevajo k oceni kakovosti in vitalnosti dreves, razlikujejo se po zanesljivosti, občutljivosti in praktičnosti. Najuporabnejše v praksi so metode, ki omogočajo hiter, mobilen in cenovno dostopen pregled, kot sta akustična tomografija in metoda električnega upora. Naprednejše in zelo natančne metode, kot sta NMR in rentgenska tomografija, so primernejše za raziskovalne namene. Priporočena je kombinacija več tehnik za zanesljivejšo diagnozo, saj nobena metoda ni univerzalno zadostna. S predstavitvijo obstoječih orodij za ocenjevanje kakovosti in vitalnosti dreves želimo prispevati k boljšemu razumevanju njihovih zmogljivosti in omejitev. This thesis presents an overview of non-destructive methods for assessing the vitality and quality of living trees, with a focus on detecting internal defects in wood. In forests, especially in urban environments, accurate assessment of internal defects (such as rot and cavities) and tree vitality is essential for timely action and ensuring public safety. The study is based on a review of domestic and, primarily, international scientific literature that examines various assessment methods. The key literature search tools were Google Scholar and Research Gate, but also Science Direct and Web of Science databases. The reviewed methods include both invasive and non-invasive techniques such as acoustic tomography, electrical resistance measurement, ground-penetrating radar (GPR), microwave scanning, X-ray tomography, chlorophyll fluorescence, Shigometry, and refractometers. The analysis showed that each method contributes differently to the assessment of tree quality and vitality, they differ in reliability, sensitivity, and practical applicability. The most useful techniques are those that are fast, portable, and cost-effective, such as acoustic tomography and electrical resistance methods. More advanced and highly precise methods, like nuclear magnetic resonance (NMR) and X-ray tomography, are more applicable research. A combination of multiple techniques is recommended for more reliable diagnostics, as no method is individually universally sufficient. By presenting existing tools for assessing tree quality and vitality, it aims to enhance understanding of their capabilities and limitations. skeniranje živih dreves neinvazivne metode za skeniranje živih dreves ugotavljanje vitalnosti dreves orodja za zaznavanje trohnobe dreves nedestruktivne metode za odkrivanje trohnobe lesa scanning of alive trees non invasive methods for scanning alive trees detecting tree vitality tree decay detection tools non destructive methods for detecting wood decay true false false [N.
