    • Abstract
  • A three-year aeropalynological study was carried out in the month of August for each of the three years 2005, 2006 and 2007 in the Beijing Olympic Park. A total of 19550 pollen grains were counted (15057 grains in 2005, 2717 in 2006 and 1776 in 2007) for the following taxa: Gramineae, Chenopodiaceae, Humulus
     L., Artemisia
     L., Ambrosia
     L. and Pinus
     L. The analysis indicated that in the three consecutive years of 2005-2007, airborne pollen types and daily number of pollen in August in the Beijing Olympic Park were closely related to environmental change and vegetation composition. The daily variations of airborne pollen displayed similar patterns in August in each of the three years, which were affected positively by periods of daily sunshine, negatively by daily relative humidity and daily precipitation. Continuously high daily temperatures and stable daily wind speeds seemed to have little effect on the fluctuation of airborne pollen.
