【 摘 要 】

The meteo-climatic arguments for the eastern biogeographic limit of beech in Romania are of particular interest to forestry, but also to geographers and climatologists. This limit marks the transition from the temperate humid climate of Western and Central Europe to the temperate continental climate of Eastern Europe. Our paper provides improved knowledge on climatic conditions that restrict the longitudinal distribution of beech at temperate latitudes in north-eastern Romania. Results show that rainfall scarcity and high temperature in the March-June interval, added to temperature drop below the freezing point in April-June are the main climatic conditions that limit beech expansion eastward of this biogeographic limit.
