中国台湾海峡两岸原始被子植物的起源、分化和关系

文章分析了中国台湾海峡两岸共有20个原始被子植物科的地理分布，区系分化，起源以及它们之间的关系，进一步证明台湾海峡两海的植物区系是一个统一的区系，台湾省是一个东亚植物区系的马来西亚植物区系交汇，而以东亚植物区系成分占优势的地区，台淡丰富的原始被子植物特有种，大多种是在台湾同大陆分离以后形成的，带有新特有的种的性质，中国大陆同台湾现存的原始被子植物科属在区系上是共同起源的，起源的时间和地区可以追溯到中生代的华夏古陆，即在白垩纪末台湾同大陆第一次分裂之前就已经表成了，第四纪冰期大陆同台湾之间的陆桥，对两岸原始被子植物的分布几乎没有影响。

Origin, Diversification and Relationships of Primitive Angiospe rms on both Sidesof the Taiwan Strait, China

What analyzed in the present paper is the distribution, diversification, origin and relationship of 20 primitive angiosperm families occurring commonly on both sides of the Taiwan Strait, China. The results confirm the floristic integrity on both sides and reveal that the Taiwan flora have mixed elements from the eastern Asiatic flora and the Malesian flora, but mainly belonging to the former. The abundant endemic species in the primitive families of the Taiwan flora are mostly neoendemic elements, which formed after the separation of Taiwan from the mainland. The primitive angiosperm genera and families in Taiwan and Mainland China have a common origin and the origin time and place could be dated back to the Late Cretaceous in the Cathaysian ancient land before Taiwan firstly seperated from the mainland in the Mesozoic. The land bridge during the Quaternary glacier between Taiwan and Mainland China had seldomly affected the distribution of primitive angiosperms on both sides of the Taiwan Strait.
