Abstract
Načrtovanje donosov je temeljno orodje nege in usmerjanja prihodnjega razvoja gozdov. Zato je strokovno zahtevno in hkrati deležno zanimanja javnosti; če neprej, pa zagotovo v času izvedbe načrta. Prispevek prikazuje posebnosti načrtovanja donosov v skupini gozdnogojitvenih zvrsti s površinsko izmenjavo generacij, skupini zvrsti temelječi na načelu oblikovanja sestojev in pri sproščeni tehniki gojenja gozdov (STG). Pri sonaravnem gojenju gozdov je za določanje donosov sicer koristna uporaba matematičnih modelov, vendar so temeljne odločitve prepuščene gozdarskemu strokovnjaku na terenu, ki črpa iz informacij kontrolne metode. Gospodarsko in ekološko pomembne odločitve so priobnovi gozdov. Te so rezultat optimiranja različnih kazalnikov gozdnega ekosistema in njegovega okolja. Ekonomsko najugodnejši čas obnove večinoma ni v neskladju z drugimi funkcijami gozda. Pri prebiralnem gojenju gozdov je načrtovanje donosov odvisno od zgradbe gozda, pri skupinsko postopnem gojenju tudi od površin razvojnih faz, pri STG pa uporabljamo sestavine obeh načinov načrtovanja donosov.

Title:Silvicultural views on yield regulation
Abstract:
Yield regulation is the basic tool for forest tending and affecting the futureforest development. Therefore it is professionally demanding and at the same time interesting for the public, at latest when the plans are executed. This article represents particularities of yield regulation for silvicultural systems with exchange of generations in areas, for group of uneven-aged systems and for "free style" silvicultural system (STG). In close-to-nature silviculture the use of mathematical models is helpful, but the basic decisions are in the hands of the forestry expert in the terrain who utilizes the information gained by the control method. Regenerating the forests, economically and ecologically important decisions are taken. They are a resultof optimization of various forest ecosystem and its environment indexes.Most often, economically favorable time for regeneration does not contradict other forest functions. In selective silviculture, the yield regulation depends on forest composition, in group of uneven-aged systems alsoon development phases areas, and in STG, elements of both yield regulationmethods are used.

Keywords:silvicultural system, tending model, forest regeneration, optimization, cut, control method
