[fr] Cette étude propose une méthode d'estimation rapide du volume à l'hectare total ou ventilé par catégories de grosseur commerciales pour des peuplements d'épicéa (Picea abies KARST) situés dans la partie sud de la Belgique. L'analyse d'environ 1 800 unités d'échantillonnage a permis d'établir des relations satisfaisantes entre les proportions de volume bois fort tige correspondant à diverses catégories de grosseur et la circonférence de l'arbre de surface terrière moyenne. [en] Results of large forest inventories have been analyzed in order to estimate timber product percentages in coniferous stands (Picea abies KARST) located in the southern part of Belgium. Stand volume functions based upon top height and basal area give total volumes per hectare. The volumes estimated by commercial girth classes are presented as functions of mean stand girth.
