摘要：栎属(Quercus L.)的化石最早见于始新世。早期的栎类为常绿种类,它们与现代种的亲缘关系难以确定。渐新世时落叶的栎类开始繁衍,这与当时全球气候不断恶化以及由此引起的高纬度地区栎类的南退有关。中新世是我国栎类发展的鼎盛时期,到上新世时,绝大多数现存种的原始类型已经出现,栎类的分布格局已与今日的面貌接近。新第三纪时,中亚荒漠的形成和喜马拉雅造山运动,对我国栎类的演化有重要影响。文中还分析了我国第三纪栎类与北美、欧洲同期栎类的关系。
The earliest undoubted fossils of Quercus L. are not found until Eocene,although the oaks may have originated prior to the late Cretaceous. Most oak species from the old Tertiary rocks, which are assumed to be evergreen and ranged the montane tropics and montane subtropics near the sea,can scarcely be referred to modern species. Both diversity of oaks and their dominance in flora increased in Oligocene and gradually reached their prosperous stage. In Miocene,there many existed extinct species groups and many essentially modern species were present. The oak distribu- tion pattern in Pliocene was similar to modern one. The first deciduous oak species appeared in the middle Oligocene in Northeast China when the oaks in high latitude retreated southward caused by the spreading of colder and drier climate. In early Neogene oaks disappeared in Northwest China because of the occurrence of the Middle Asian Desert. Meanwhile,the species of Sects. Suber and Englerianae evolved in Southwest China as a result of orogenesis of the Mountain Himalaya. The fossil records indicated that the interchange of oaks between North America and China was not ended until the middle Miocene,while the linkage between Europe and China was not ended until the early Pliocene.
