Abstract :
[en] A pilot study has been carried out in order to assess the productivity of various sites for oak (Quercus sessilis) growth in belgian Ardenne. Site quality is evaluated by the measurement of top height at a kay dominant girth of 160 cm. Such a site index seems to be well suited to unevenaged forest structures. Some other calcultations concern relationships between the index and various site factors as aspect, soils and species of plants naturally occuring on the studied areas. Estimations of stands volumes are also made with particular stand volume equations. [fr] Une étude pilote destinée à chiffrer localement la productivité des milieux de croissance du chêne rouvre en Ardenne (région de Wellin) a permis de mettre en évidence un critère dendrométrique basé sur la hauteur dominante atteinte à la circonférence dominante de référence de 160 cm. Cet indice, à première vue bien adapté aux structures inéquiennes, peut être estimé de manière satisfaisante, à l'aide d'équations de régression multiples prenant en considération un nombre réduit de variables stationnelles, plus précisément l'exposition et diverses espèces végétales indicatrices. Associé à d'autres variables dendrométriques, il sert également de base à l'estimation du volume des peuplements sur pied dans divers milieux de productivité.
