Aeropalynological Study of Taipei Suburban (New Flower Garden City)

並列摘要


Airborne palynomorphs had been investigated in the New Flower Garden City, Taipei suburban one year during 1980 to 1981. A total of 14,044 pollen grains and fern spores were obtained. including 18.54% fern spores. 4.15% gymnospermous pollen grains, and 77.31% angiospermous pollen grins. 95.75% of palynomorphs were identified. They belong to 56 families and more than 100 taxa.The dominant pollen taxa varied seasonally. Pollen grains of Trema orientalis appeared most abundantly in spring; Cyatheaceae spores in summer; Humulus scandens and Miscanthus pollen grains in autumn; and Morus australis and Villebrunea pedunculata in late winter.The local common species and complicate vegetation in this valley were reflected in the assemblage of airborne palynomorphs. Airbone palynomorphs were mostly of short distance dispersion, and their spectra were strongly localized.The effects of meteorological factors on airbone palynomorphs were varied with different taxa. However, in general, the rainfall could decisively decrease the pollen content in the air, but other factors impacted on them as a whole.
