本文的水青冈属的分子系统发育和泛生物地理学研究的结果是一致的，都说明水青冈属植物在物种形成和演化的过程中，受到大陆漂移等地质历史事件的影响。

The results of the study of molecular phylogeny is consistent with the Panbiogeography result . This indicates that the process of formation and evolution of Fagus genus were affected by the continental drift and the geological history events .
