Abstract:V prispevku je predstavljen sestojni simulator MORSE (MOdel Razvoja SEstojev), ki omogoča simuliranje razvoja enomernih mešanih sestojev na ravni posameznih sestojev in večji prostorski ravni. Zgrajen je iz treh modulov, ki obravnavajo rast, mortaliteto in ukrepanje (redčenje in obnova). Regresijski model razvoja dominantnega premera sestojev je temeljni algoritem, izdelan na podlagi empiričnih podatkov. Za zagon simulatorja so potrebni vhodni podatki o sestojnih in rastiščnih znakih, ki so preprosto določljivi. MORSE simulira razvoj sestojev za obdobje dvesto let glede na upravljavske odločitve o redčenju (jakost, pogostnost, zvrst, pospeševanje drevesnih vrst) in obnovi (ciljne velikosti, pomladitvena doba, čas in jakost pomladitvenih sečenj, pomladitveni cilj). Mogoča sta dva načina določanja režima redčenj: i) eksplicitna določitev terminov in jakosti redčenj in ii) posredna glede na primerjavo dejanske in optimalne temeljnice sestoja. Razvoj sestojnih znakov za opredeljeno obdobje je prikazan grafično in v preglednicah. Za isto obdobje so navedeni parametri poseka in mortalitete drevja. MORSE je sedaj v fazi preverjanja na sestojni ravni, potem sledi razvoj simulatorja na večji prostorski ravni. V prispevku so prikazane variante razvoja testnega sestoja glede na različno ukrepanje.

Title:MORSE – forest stand simulator
Abstract:In this paper, the stand simulator MORSE is presented. It enables simulating stand development of even-aged mixed forest stands at the single stand level and the landscape level. It consists of three modules, dealing with growth, mortality and management (thinning and regeneration). The diameter increment of the forest stand dominant diameter is a key algorithm integrated into the simulator. Data on stand and site characteristics, which can be determined easily, are needed for the simulation run. The simulation period is 200 years. The simulated stand development depends on the decision on thinning (intensity, frequency, type, favouring tree species) and regeneration (target dimension, regeneration period, intensity and frequency of regeneration cut, tree species of a regeneration). Thinning regime is defined i) explicitly, by defining the time and intensity of thinning or ii) the time and thinning intensity are defined based on the comparison of optimal and real stand basal area. Stand development in the selected period is presented by main stand parameters in the graphical and table form. For the same period, parameters of mortality and harvest are presented. MORSE is now in the testing phase at the single stand level, and then an upgrade at the landscape level will follow. In the paper, variants of the stand development of the case study under various management decisions are described
