植物区系学中特有现象的研究进展(Ⅰ)——概念、类型、起源及其研究意义

Advance on Endemics in Floristics——concept,type,origination and studied significance

植物区系学中的特有现象是其研究的重点内容 ,对特有现象的概念、类型、起源及其研究意义作了详细的论述 ;其次 ,总结了中国植物区系的基本情况、生活型、分布区学、水平分布、垂直分布与起源等研究成果 ;第三 ,介绍了研究特有现象的形态—地理学方法、细胞地理学方法和等位酶分析方法 ;第四 ,指出了中国植物区系中特有现象研究所面临的困境 ,认为应该集中力量重点研究滇黔桂、横断山脉以及华中等 3个地区的植物区系基本特征、组成、起源。

The endemics in the floristics is the emphasis contents of the research.First,it systematically discusses the concept,type,origination and studied significance of the endemics in the floristics. Secondary,it overall summarises the studied achievements of the basic condition,life-form,areography,level distribution,vertical distribution and origination of the endemics of the floristics in China.Third,it introduces the research methods of the endemics in floristics by the morphology and geography,the cytogeography and the isozyme analysis. Last,it putts forward to be faced with problem of the endemics of the floristics in China,that the authors think emphasis to study the basic characteristics,formation,origination,evolution and spread of the endemic elements of the three floristic regions of Tian(Yunnan)-Qian(Guizhou)-Gui(Guangxi),Mt.Hengduanshan and Central China and so on.
