Abstract: As one of the components of urban air pollutants, pollen seriously affects our living environment and health, which is highly concerned by government and scientific community. Here, based on the airborne pollen data of past 60 years in Beijing-Tianjin-Hebei region, we summarize the major pollen types and their seasonal distribution characteristics in this region, and the data shows that the annual variation of airborne pollen concentration basically follows the ‘bimodal' pattern, viz. arboreal pollen such as Cupressaceae, Salicaceae and Betulaceae dominate the peak in spring, while herbaceous pollen like Artemisia, Humulus/Cannabis sativa, Chenopodiaceae/Amaranthaceae dominate the peak in summer and autumn. Then we discuss the dominant meteorological factors related to pollen concentration and the characteristics of pollinosis. Furthermore, we point out that human activities (e.g., land reconstruction and roadside tree planting) may have an impact on the changes of airborne pollen composition in Beijing over these years. Finally, we emphasize the important role of future long-term airborne pollen monitoring in atmospheric environment assessment, pollinosis prevention, and urban greening construction.
