Distribution, regeneration and succession ofFagus

Abstract

The distribution, regeneration and succession ofFagus in China were systematically analyzed in comparison with those in Europe and in northern America. The results showed that it was very likely that China was the distribution center ofFagus, which originated in eastern Asia, migrated into northern America and then into Europe. Distribution ofFagus in China is relatively independent with seven species. The main reason for wide distribution ofFagus in Europe, but unitary species, is possibly the influence of the climate in Quaternary Period, and also related with influence of the ocean climate.
