板块构造对我国东南沿海地区植物区系与东亚—北美间断分布的关系

我国福建、浙江、台湾、广东沿海及海南和南海等东南沿海,在地质上属华夏地块和台湾,从各地植物区系的相似性以及古植物区系地理的研究表明;我国东南沿海地区植物区系是一个统一的整体。东亚-北美间断分布是板块构造运动的结果,我国东南沿海地区有着丰富而古老的东亚-北美间断分布的属种,并有一些主要的原始的科属和种类,可能是东亚-北美间断分布的发源地之一。

Plate Tectonics on the Relationship Between the Flora of the Southeastern China and the North America

This paper dealt with the flora of coastal region of the southeastern China including Fujian, Zhejing, Guongdong coastal region, Taiwan, Hainan island and the South China Sea. It was called Cathaysia massif in geology. The floristic similarities between each other part in region and the data of palaeobotany and palaeoflora showed that it is a whole flora of the coastal region of the southeastern China.The discontinuous distribution of the easten Asia and north America is the result of the plate movement. The flora of the coastal region of the southeastern China is characterized including a great number old genera and species of the discontinuous distribution of eastern Asia and north America. On the other hand, there are many families and genera of important primitive angio-sperms. It may be one of the birthplace of the discontinuous distribution of eastern Asia and north America.
