The impact of forest openness degree in the M.U. Ćorkovača - Karlice on selection of timber harvesting system

Planiranje je složen proces koji zahtjeva racionalno donoše-nje odluka, što u suvremenom gospodarenju šumama pod-razumijeva donošenje planova o otvaranju šuma i odabiru sustava pridobivanja drva. U ovom radu prikazana je analiza pogodnih terena za odab-rane sustave pridobivanja drva na području gospodarske je-dinice Ćorkovača - Karlice, kao ograničavajući čimbenici u-zeti su: nagib, srednja udaljenost privlačenja, te srednji prsni promjer. Unaprjeđenje primarne prometne infrastrukture je prove-deno u ArcGIS programskom paketu, te je temeljem dobi-venih podataka provedena analiza parametara procjene kva-litete mreže šumskih prometnica postojećeg i unaprijeđenog stanja: primarne klasične otvorenosti, primarne relativne otvorenosti, geometrijske srednje udaljenosti privlačenjaPlanning is a complex process that requires rational decision-making, which in the modern forest management means ma-king plans regarding forests accessibility and selecting timber extraction systems. In this paper, the analysis of suitable terrains for selected tim-ber extraction systems in the area of the management unit Ćor-kovača - Karlice is presented, and taken limiting factors were: slope, mean distance of extraction, and mean breast height di-ameter. The improvement of the primary transport infrastructure was carried out using the ArcGIS software package. Based on the obtained data it was performed analysis for the parameters of the quality assessment of the existing and improved forest road network: primary classical openness, primary relative open-ness, geometric mean distance of extractio
