Flora and species diversity of wild seed plants in Qiangtang Plateau
To analyze and discuss the composition,elements,and characters of the flora in Qiangtang Plateau,and to provide data support and reference for the study and conservation of biodiversity in this region.Based on the field investigation,specimen collection,and literature review,the list of wild seed plants in Qiangtang Plateau was summarized and compiled.Floras in Qiangtang Plateau and surrounding 18 regions were analyzed by cluster and principal component analysis,and the composition,properties,characteristics,and evolutionary history were also analyzed systematically.Conclusions were drawn as follows:1)There are 370 species of seed plants found in Qiangtang Plateau belonging to 158 genera and 44 families.The species in the flora are relatively unabundant.2)The distribution area types of families and genera are dominated by temperate components,and the distribution area types of genera are dominated by the distribution in the North Temperate Zone,Temperate Asia,Mediterranean Sea,and Central Asia,reflecting the close connection with the Paleo-Mediterranean flora.3)The Qiangtang Plateau has become the cradle of some representative taxa(Hippophae,Odontostemma,Allardia,Dilophia,Christolea,and Solms-Laubachia),which their origins are closely linked to the region.4)In terms of phytogeographic compositionat the genus level,the flora in Qiangtang Plateau has the highest similarity to the flora in Altun Mountains.
