| 摘 要： | 甘肃白水江国家级自然保护区地理位置独特,植物种类丰富,种子植物共计183科、718属、1970种.分析了区内各属的数量、分布型、生活型等几个方面,结果表明：本区系是一个温带区系,但杂有一定程度的热带-亚热带性质;地理成分复杂,体现其与世界及国内各植物区系的广泛联系;原始与年轻类群大量并存,表明该区既是古老类群的保存中心,又是新类群分化发生的活跃区域;从中国特有属的分布式样等证据来看,本区与华中区系的关系更为密切.

| Abstract: | The Baishuijiang national reserve located in transitional zone from north subtropic to south warm temperate is an important region for floristic studies.The reserve has a rather rich flora which is composed of 1970 species,718 genera and 183 families of seed plants.The quantity,arealtype and life form of genara in this area are analysed,the results show:(1)This flora is a temperate one with certain tropical and subtropical character.(2)The geographical elements are complex,which indicate its broad contact with international and domestic floras.(3)The primitive genera coexist with developmental ones,as shows that Baishuijiang reserve is a storage of ancient groups and active region of differentiation of new ones.(4)According to the distribution pattern of endemic genera to China,the flora is more closely allied to central China. |
