Modern Pollen Rain in the Tibetan Plateau

The basis for the interpretation of fossil-pollen assemblages in terms vegetation and climate is present-day relationship to pollen rain. Detailed modern spectra from Tibetan Plateau are described here explore between rain vegetation. Two hundred thirty four (234) surface samples were collected moss polsters, top soil, lake sediments forests, shrublands, shrub meadows, steppes, deserts Plateau. Pollen each type detailed using percentage data, compared descriptively numerically cluster analysis. forests characterized by high percentages tree types including Pinus, Abies , Picea, Quercus, Betula . shrublands have highest amounts pollen. dominants such as Rhododendron Juniperus Salix Quercus well-represented most these spectra. meadows less than those but more steppes deserts. frequent this Rosaceae. Most dominated Cyperaceae very occur alpine-marshy meadows. Stipa Poaceae pollen, percentages, whereas Artemisia arid Chenopodiaceae. Main can be distinguished their rain, i.e., do reflect at local regional scale This database thus used pollen/vegetation pollen/climate relationships a variety numerical methods.
