Abstract
|
|
|
The distribution of beech species(FAgus) and beech-dominated forests along climatic gradients in the Northern Hemisphere was studied by use of taxonomic and ecologicalliterature. The genus Fagus as a whole occurs over the range of 4.5 to 20.0℃ mean annual temperature and 600 to 1000 ㎜ in lower limit, mean annual precipitation. At the higher end of the temperature range, beech occurs in zones with relatively high growing-season precipitation. Edaphically, beech species and beech-dominated forests tend to occur on mesic, moderately fertile sites.
Beech-dominated forests occur in a limited portion of the climatic range of the genus with sensilive responses to other environmental factors. The distributional range of beech-dominated forests on a global scale depends more on climatic factors and geological events than on soil conditions or other factors, summarizing the facts obtained by many researchers on beech dominated forests.
