摘要
水青冈属(Fagus)植物不连续分布在中国南方亚热带山地,是北半球落叶阔叶林的重要建群种。笔者结合欧洲和日本关于水青冈的研究成果,探讨了中国水青冈在欧亚大陆的起源问题,水青冈林的结构,其生长和更新特性,以及水青冈遗传多样性的研究进展。结果表明,中国是水青冈属的分布中心,包括长柄水青冈(F.longipetiolata)、米心水青冈(F.engleriana)、亮叶水青冈(F.lucida)、台湾水青冈(F.hay-atae)和巴山水青冈(F.pashanica),但其分布区域较狭窄,遗传多样性不高,并有更新不足的现象。
The genus Fagus is discontinuous distributing at semitropical mountainous area in the south of China, which is also important constructive species in evergreen broadleaved forest in the Northern Hemisphere. Integrated the study of Europe and Japan, we discuss the origination of chinese beech in Eurasia, the growth and regeneration pattern of beech forest, and the Fagus genetic diversity. The results showed that China was the distributional center of Fagus, including F. longipetiolata、F. engleriana、F. lucida、F. hayatae and F. pashanica. But the distribution area of fagus population was very limited, the genetic diversity was low, and the revegetation of beech forest was not good in some area.
