He proposed that the present continents once comprised one large landmass which he named pangaea . 他提出目前的大陆以前是连在一起的一个巨大陆块，他把这个陆块称为联合古陆。

Continental drift the theory that present - day continents have arisen by the breaking up and drifting apart of a previously existing ancient land mass ( pangaea ) 大陆漂移说：现今的大陆是由以前的大陆破裂并分离漂移而逐渐形成的学说。

The cause of the permian extinction might have been global cooling , volcanic eruptions , or a decrease in the continental shelf area during the formation of pangaea 二叠纪绝种的起因也许已经是全球性冷却,火山爆发,或减退在大陆架区域在pangaea的形成期间。

The information system pangaea is a public data library on the internet aimed at archiving , publishing and distributing geocoded data with special emphasis on environmental , marine and geological research 描述: “地质与环境数据网络” （ pangaea ）是一个网络数字图书馆，目标是存档、出版与发布有关环境、海洋与地质研究方面的数据。

The distribution of all the genera and species ( including new taxa and new data by present research ) of the world are summarized , according to the history of continental drift and the result shows that empoascini originated in the oriental region in pangaea 145maago . zoogeographical analysis of all the taxa in china shows that most of the genera and species of empoascini are distributed in the oriental region , which is identical with the geographical distribution worldwide , i . e . most taxa distribute in the tropical and subtropical zone . phylogenetic analysis of 40 chinese genera of empoascini with one outgroupikranewa is presented in this paper 在生物地理及区系方面，总结了世界已报道及本研究新发现单元共计88属1183种在世界各大动物地理区的分布情况，结合大陆漂移学说的有关知识，认为小绿叶蝉族应起源于东洋区，起源时间在联合古陆时期(约145ma以前) ；分析了中国已报道及本文新发现该族共40属263种在中国动物地理区划的归属，结果表明，中国小绿叶蝉族的种类分布以东洋区占优势，明显多于古北区，这与世界该族昆虫大多分布于热带、亚热带的结果相一致。
