Abstract

BARRETO, Luís Soares. SB-ROBUR+H A Simulator for Four Even-Aged Self-Thinned Stands of Quercus robur and Another Hardwood. Silva Lus. [online]. 2002, vol.10, n.1, pp.111-117. ISSN 0870-6352.

The author uses his conceptual model of tree competition to propose a simulator for the following even-aged, self-thinned mixed stands: Quercus robur+Acer pseudoplatanus, Quercus robur+Betula pendula, Quercus robur+Fagus sylvatica, Quercus robur+Fraxinus excelsior. Given the closeness of the competitive ability of these species in each stand, the simulator, written in BASIC, uses Gompertz equations to simulate the dynamics of the number of trees within each stand. In addition to listing the SB-ROBUR+H simulator, a sample of its output is also presented.

Keywords : Acer pseudoplatanus; Betula pendula; Fagus sylvatica; Fraxinus excelsior; Quercus robur; self-thinned even-aged mixed stands; simulation.
