Determination of volüme and volüme increment in young and immature stand of our beech forest is needed in the forest yield, forest management, forestry economic and silviculture studies. Volüme tables are usually used in volüme calculations. Volüme tables don’t generally give the volumes of thin diametered trees. In this research, single and double entry volüme tables for beech trees Which have an important natural range in Turkey have been constructed. Thirteen different mathfcmatical models developed for constructing of the volüme tables have been examined, and the most convenient model for data has been selected by making critiques from the statistics point of vievv. Besides, the relationslıips between diameters and volumes outside and inside bark have also been determined.
