    Abstract:

    Tibetan Plateau (TP) and adjacent regions have the most diverse of alpine plants in the world.The phylogeography of alpine plants in this region could explain the relationship between their demographic history with TP uplift and Quaternary glaciation.Base on the phylogeographic researches of 36 alpine plants in the published literatures,two generalized phylogeographic patterns were concluded:(1)Glacial retreat and subsequent recolonization of the platform from peripheral glacial refugia;(2)Existence of cryptic (or micro-) refugia outside the major glacial refugia,resulted from geographical isolation,followed local expansion during postglacials.The rapid TP uplift promoted intraspecific divergence and allopatric speciation within the late Tertiary,the followed periodic climate fluctuations accelerated the situation.These are the main reasons for shaping the modern phylogeographic patterns.Additionally,Hengduan Mountains as the major glacial refugia,have important implications for Evolutionary Biology and Conservation Biology.At last,several research fields of phylogeography of alpine plant in TP were provided,including species selection,sampling strategy,gene fragment selection and methods.
