Prostorni raspored stabala smrče u rezervatu prirode 'Jankove bare' na Kopaoniku

Abstract

Metodologija i aplikativnost istraživanja oblika prostornog rasporeda stabala u šumarstvu Srbije nedovoljno su poznati i prezentovani. U radu se, na bazi matematičko­statističkih principa, analizira način prostornog rasporeda stabala smrče u rezervatu prirode 'Jankove bare' u NP 'Kopaonik'. Korišćeni su pojedini metodi iz grupe metoda distanci: metod Kotara (1993), T2­metod i metod indeksa disperzije rastojanja (Johnson, Zimmer, 1985). Rezultati istraživanja u čistoj raznodobnoj sastojini smrče na bazi sva tri metoda pokazali su da se stabla smrče raspoređuju slučajno po površini sastojine. Stoga, uslovi sredine na istraživanom objektu mogu se smatrati homogenim i podjednako prikladnim za rast stabala, te da ne postoje značajnije interakcije između stabala, što bi uslovilo izraženiju konkurenciju stabala u odnosu na hranljive materije, vodu i sl.

The methodology and applicability of the study of spatial distribution of trees in Serbian forestry have been insufficiently reported and presented. This paper, based on mathematical­statistical principles, analyses the method of spatial distribution of spruce trees in the Nature Reserve 'Jankove Bare' in the National Park 'Kopaonik'. The following methods in the group of distance methods were applied: Kotar's method (1993), T2­method, and the index of distance dispersion (Johnson, Zimmer, 1985). The study results in a pure uneven-aged spruce stand based on all three methods showed that spruce trees are randomly distributed over the stand area. Therefore, environmental conditions in the study stand can be regarded as homogeneous and equally suitable for tree growth, and there are no significant interactions between the trees, which could cause a higher competition between the trees for nutrients, water, etc.
