The surface pollen and relative pollen production of the desert vegetation of the Alashan Plateau, western Inner Mongoli

This preliminary investigation focuses on the comparison of the recentpollen precipitation and its related vegetation of eight different plant communities in the Alashan Region, the most western part of the Inner Mongolia Autonomous Region. Most zonal and azonal communities can be well identified by their pollen spectra. Relative pollen production factors of various plant taxa have beencalculated and the following sequences from over- to under represented taxa have been found for zonal vegetation: Chenopodiaceae, Artemisia, Ephedra, Nitraria,Reaumuria, Calligonum, Zygophyllum; and for azonal vegetation: Peganum, Populus, Tamarix, Lycium.
