摘要

Beech tree occurs as a mountain tree in many forests in south of Caspian Sea except in easternareas of low effective rainfall. It rarely grows under 250in and above 2500m altitude in southCaspian Sea areas and grows up to 50 m tall as a dominant in dense forests. The vertical struc-ture of beech forest studied on three slope directions at three altitudes (500-1500-2300m). Theresults show there is a relationship between canopy form (height, bending) and wind speed anddirection. Since the tallest trees were less than 20m, canopy form is different from trees above20m height and it will depend on slope direction, altitude and wind speed and variation of them.
