中国裸子植物极富多样性，起源古老，孑遗、特有类群众多，对探讨区域生物多样性的结构、特征具有重要意义。论文以中国中部东西中轴线上的台湾山地、武夷山、井冈山、武陵源、峨眉山、哀牢山、南迦巴瓦峰等山地的裸子植物区系为对象，分析其地理成分组成，探讨与生态因子的相关性，主要结果表明：①中国西部并不是裸子植物最丰富的区域，大陆东部第三级阶梯的属种更富多样性；②属的地理成分，与主要的区域生态因子如海拔、降水量、热量等具有相关性；③中国特有属在东部第三级阶梯明显较多，而在西部高山种系分化明显；④台湾山地较为丰富和独特；南迦巴瓦峰的冷杉属等较其他几个地区更丰富。研究对揭示裸子植物的分布规律具有重要意义。

The Chinese gymnosperm flora is with abundant diversity,ancient origin,and a lot of relict species,and endemic species,which is significant for revealing the construction of local biodiversity and characteristics.In this paper,taking the gymnosperm floras from Taiwan Mountains,Mount Wuyi,Jing-gang,Wulingyuan,Emei,Eluo,and Namjagabrwa as the research objects,the authors study the compo-sition of gymnosperm geographical elements,discuss the relationship between the floras and climatic,ec-ological factors.Following results were obtained:①In the west China,it is not the floras with abundant gymnosperm species;The east mainland China,the third ladder,has more abundant gymnosperms.②The geographical elements of genus are relative to local ecological factors,such as elevation,rainfall, quantity of heat.③ The endemic genera to China are abundant in the east third ladder.④ In Taiwan, the gymnosperms are with more abundant genera and species;the Abies in Namjagabrwa are more than the other 6 regions.The results from the study are important for indicating the evolution and distribution patterns of gymnosperms.
