The total carbon stock amounted to 324.8 tons C ha-1 in the oak-beech stand and 321.4 tons C ha-1 in the ash stand. In the oak-beech stand 41.5 of the total C was found in the soil organic matter 11 in the litter layer and 47.5 in the vegetation. In the ash stand the soil organic matter contained 53.0 of the total C stock the litter layer only 1.0 and the vegetation 46.0 . Most vegetation carbon was found in the stems of the trees 51.1 in the oak-beech and 58.7 in the ash stand . Although total carbon storage appeared to be very similar distribution of carbon over the different ecosystem compartments was related to species composition and site characteristics. carbon pools mixed deciduous forest Fagus sylvatica L. Fraxinus excelsior L. Quercus robur L. Résumé - Réservoirs aériens et souterrains de carbone dans deux peuplements forestiers feuillus situés en Flandre Orientale Belgique . L immobilisation de carbone C a été étudiée dans un peuplement mixte hêtre-chêne et un de frêne situés dans la forêt ex-périmentale de Aelmoeseneie âgée de 80 ans. Le stock de carbone est estimé à 324 8 tonnes de C ha-1 dans le peuplement de hêtre-chêne et à 321 4 tonnes de C ha-1 dans celui de frêne. Dans le peuplement de hêtre-chêne 41 5 du C total est localisé dans la matière orga-nique du sol 11 dans les couches organiques et 47 5 dans
