摘要
植物区系反映了某一地区所有植物种类的组成 ,现代和过去的分布以及它们的起源和演化历史。梵净山 ,荔波茂兰自然保护区是贵州省内两种不同类型的植物群落 ,对它们进行植物区系分析比较 ,是研究贵州主要植被的特点、结构、分布的重要内容。通过分析可知 :两区系之间亲缘关系较小 ;在系统发育上 ,梵净山植物区系较茂兰喀斯特植物区系更原始、古老 ,后期分化更显著 ;在地理成分上 ,梵净山以温带分布较多 ,热带—亚热带次之 ,茂兰以热带分布为主 。
Flora discloses compositions,current and past distributions,origins and evaluation of all species in an area.Fanjingshan Moutain and Libo Maolan nature reserves are two types of communities.Analyses of the two communities are important in the study of characteristics,structure,and distribution of Guizhou vegetation.By comparison,it is found that Fanjingshan Mountain flora is older than that of Maolan,that botany compositions of tropic zone are more than those of temperate zone, in Fanjingsen mountain but botany copositions of Maolan is the other way round.
