摘　　要：The Qinghai-Tibet Plateau(QTP)sensu lato(sl)houses an exceptional species diversity in Asia.Todevelop a comprehensive understanding of species diversity in this fascinating region,we reviewed recentprogress from biogeographic,paleogeographic,paleontological and genomic research of both plants and animalsin the QTPsl.Numerous studies have been conducted to examine whether the QTPsluplift triggered theproduction of rich species diversity there,whether a Quaternary“unified ice sheet”eliminated plants and animalson the central plateau and how high-altitude species developed the extreme environment adaptations.Majordisputes arose about thefirst issue,mainly from different understanding of the QTP circumscriptions and relateduplift,inaccurate dating of molecular phylogenetic trees,and non-causal correlations between uplift and speciesdiversification.The QTPsluplift is spatially and temporally heterogeneous,and abundant fossils reported recentlysimilarly support such an asynchronous upheaval model across the entire region.Available phylogeographicstudies of alpine plants and animals suggested their glacial refugia in the central QTPsl,rejecting a unified icesheet during the Last Glacial Maximum.Genomic evidence from a limited number of alpine species has identifiednumerous candidate genes for high-altitude adaptation.In the future,more studies should be focused onspeciation and adaptation mechanisms of the alpine species in the QTPslbased on the cutting-edge methods.
