Aeropalynological Study of Taipei Basin, Taiwan

Abstract The results of daily collection of atmospheric pollen grains and spores in Taipei, Taiwan during June 1974 and May 1975 are presented. A total of 26307 grains belonging to more than 62 taxa were obtained. Most were of short distance dispersion. The results show that 56% were tree pollen grains with over 38 taxa, 22.7% grass pollen grains, 10.2% fern spores with over 13 taxa, 9.1 % weed pollen grains with over 10 taxa, and 2% unidentified taxa. Of the annual count, 20.7% were collected in the summer and were dominated by fern spores. In the autumn 26.3 % were collected and were dominated by grasses. In the winter, 4.4% was collected and in the spring, 48.6% with trees dominating. The relationships between pollen occurrence and meteorological factors is also discussed.
