Flora of seed plants in Tsong-Kha mountains on the eastern Qinghai-Tibet Plateau
摘要
Abstract
This study aims to elucidate the characteristics of the wild seed plant flora in the Tsong-Kha Mountains through historical literature review and floristic investigation,thereby providing a scientific basis for biodiversity conservation in the area.Field surveys along transect lines were conducted to statistically analyze plant species composition,floristic elements,characteristic taxa,dominant families,and geographical distribution patterns.A total of 381 seed plant species belonging to 98 genera and 38 families were recorded in the Tsong-Kha Mountains,indicating a relatively depauperate flora.Both family and genus distribution types were predominantly temperate,reflecting the marked temperate nature of the flora.Species can be divided into 8 types and 2 varieties,with Chinese endemic species accounting for the largest proportion,followed by China-Himalayan distribution.Eight dominant families were identified:Asteraceae,Poaceae,Ranunculaceae,Rosaceae,Fabaceae,Gentianaceae,Amaranthaceae,and Brassicaceae.Additionally,29 rare or endangered plant species were documented,accounting for 7.61%of the total species,highlighting the presence of notable conservation priorities.The flora of Tsong-Kha Mountains exhibits diverse geographical ele-ments,obvious temperate characteristics,and harbors a certain proportion of rare palnt species.However,its species richness is comparatively lower than that of the Qilian Mountain sector.These findings underscore the need for targeted conservation strate-gies to protect this ecologically significant but vulnerable flora.关键词
