Sastojine jele i smrče sa planskog aspekta na području gazdinske jedinice "Đerekarski Omar" u jugozapadnoj Srbiji

Abstract

U radu su predstavljeni rezultati istraživanja mešovitih sastojina jele i smrče na području gazdinske jedinice "Đerekarski Omar" koja se nalazi u jugozapadnoj Srbiji. Sastojine koje su predmet ovog istraživanja pripadaju kompleksu frigorifilnih četinarskih tipova šuma. Šumama u gazdinskoj jedinici "Đerekarski Omar" gazduje se u skladu sa planskim dokumentima počevši od 1961. godine, kada je izvršeno prvo uređivanje ovih šuma. Rezultati ovog rada nastali su na osnovu premera stacioniranih oglednih polja postavljenih u homogenim delovima sastojina. Na svim oglednim poljima jela je dominantna vrsta drveta. Vrednosti zapremine i zapreminskog prirasta u istraživanim sastojinama su znatno iznad prosečnih na nivou Srbije za sastojine jele i smrče. Zdravstveno stanje sastojina je dobro, pri čemu pozitivnu okolnost predstavlja proces prirodne obnove ovih sastojina kako na mestima gde je došlo do otvaranja sklopa tako i pod potpunim sklopom sastojine. S druge strane, broj stabala, srednji prečnik stabala i kvalitativna struktura stastojine ukazuju na potrebu detaljne analize planiranih radova.

The results of the research of fir and Norway spruce mixed stands in the area of Đerekarski Omar Forest management unit situated in southwestern Serbia are presented in this paper. The stands which are the subject of this research belong to a complex of frigophilic coniferous forest types. The forests in the Đerekarski Omar Forest management unit are managed in accordance with the planning documents starting from 1961 when the first planning of these forests was performed. The results of this paper were based on the measurement of stationary sample plots established in homogeneous parts of the stands. In all sample plots fir is a dominant tree species. The values of volume and volume increment in studied stands are significantly above the average at the level of Serbia for fir and Norway spruce stands. The health condition of the stands is good, whereby a positive circumstance is the process of natural regeneration of these stands both on locations where there is a sparse canopy and in closed-canopy stands. On the other hand, number of trees, mean tree diameter and qualitative stand structure indicate the need for a detailed analysis of the planned works.
